This digital portal runs on all modern browsers and offers offline functionality for vessels when internet connections are down. ## eCare Monitor The eCare monitor module allows logging and monitoring of cooling and boiler water values, offering vessels a 6 month (offline mode) or unlimited history (online) of their system performances. The system also gives automated advice in case values are below or above the desired threshold. **How can I access the eCare monitor?** When customers are under contract with us, the ships data can also be monitored by our water treatment experts. Should the vessel be flagged in orange or red zone based on values above or below desired threshold, custom advice can appear in the monthly report. For fleet managers, a comprehensive dashboard shows the latest status of the fleet. A simple click through on the orange or red colored vessels will show directly which of the vessels systems are causing the alert. The logging values can also be customized on your desired level. This means that specific situations or systems for vessels can be integrated in the logging module, and will appear in the reports. We believe that you shouldn't have to adapt to our systems, we'll adapt to yours. **Can the monitor be installed on my device?** With the use of the Chrome browser, it's also possible to install eCare as an app on Windows and Android devices. We ensure our users the highest levels of security with data stored and exchanged via a VPS server. ![eCare Customer Platform](https://media.marine.care/original_images/Leaflet_-_eCare_Customer_Platform.jpeg) ## Key Benefits --- --- title: Publications url: "https://www.marine.care/services/publications/" type: services.ServicePage published: 2025-11-05 updated: 2026-09-21 description: Take a look at our Environmental, Social and Governance (ESG) reports, industry articles and technical publications.

The idea was simple: deliver marine-grade urea directly from barge to vessel, cutting out the IBC containers, the crane lifts and the slow, waste-heavy logistics chain that Tier III compliance had inherited from an earlier era. This set a new benchmark for how the industry could approach urea supply. That proof of concept became the foundation for something bigger. UREA-Xpress, developed in exclusive partnership with Yara and operating from the port of Rotterdam, takes everything learned from the TIER III and scales it to meet the demands of Europe's busiest port. At 600 m³ capacity with pumping rates of up to 75 m³/hour, it is our most advanced urea barge to date, and the clearest signal yet that barge-based delivery is not an experiment, but the new standard. ## TIER III - Where It All Started In the port of Houston, we launched the world's first dedicated urea bunkering barge: the TIER III. At the time, no one had operated a purpose-built urea barge in a commercial port. The TIER III changed that. The concept was straightforward: deliver urea directly from barge to vessel, cutting out the IBC handling, the crane lifts, and the logistics chain that slowed everything down. In practice, it worked better than anticipated. Bunkering time dropped by up to 80%. Tonnes of plastic waste were eliminated with every loading, and vessels in the Houston port area gained access to a Tier III supply solution that actually kept pace with their schedules. The TIER III proved the model. What had been a new idea became a new standard. ![Tier 3 beskjært](https://media.marine.care/original_images/Tier_3_beskjaert.png) **Technical specifications - TIER III** - Length overall: 18.5 m - Beam: 7.4 m - DWT / Tank capacity: 74 MT / 100 CBM - Pumping rate: 20–50 m³/hour - Max. pressure: 8–10 bar (116–145 PSI) - Pumping height: Up to 30 metres above the waterline - Hose configuration: 2 × 30 m, 2-inch chemical transfer hoses **Environmental impact per 100 m³ (vs. conventional IBC supply)** - 8–10 MT reduction in CO₂ emissions - 2,300 kg of plastic packaging eliminated - 40% reduced overall environmental footprint ## UREA-Xpress - Our Latest Innovation Building on everything learned from the TIER III, we developed UREA-Xpress in exclusive partnership with Yara. The barge is custom-built 600 m³, purposely designed for urea delivery in the port of Rotterdam. UREA-Xpress is not simply a larger version of its predecessor. It is the result of operational experience, customer feedback and a deliberate effort to take barge-based urea logistics as far as current technology allows. At six times the capacity of the TIER III, it serves the demands of Europe's busiest port, and does so with a supply chain reduced to its simplest possible form. Loading directly from Yara's Sluiskil production terminal, UREA-Xpress removes every intermediate step between product origin and vessel bunker tank. No additional transport. No interim storage. No unnecessary handling. The barge connects the terminal to the vessel, and nothing else stands between them. ![GTM-MC-HR-14](https://media.marine.care/original_images/GTM-MC-HR-14.jpg) **Technical specifications — UREA-Xpress** - Tank capacity: 600 m³ - Pumping rate: Up to 75 m³/hour - Equivalent in tank trucks: 25 per loading - Equivalent in IBC containers: 600 per loading **What a single loading replaces** - 25 tank truck journeys into port, reducing road congestion, working hours, and transport emissions - 600 IBC containers, each containing approximately 20 kg of HDPE plastic and 35–40 kg of steel, typically handled two to four times each - 30–40 tonnes of packaging material per loading - Thousands of individual crane and truck lifts across the supply cycle _UREA-Xpress operates from the port of Rotterdam.

They extend to every piece of equipment on deck. --- # Why clean deck equipment demands the same precision as a clean engine **Why clean deck equipment demands the same precision as a clean engine** Compliance and efficiency does not stop at the engine room. They extend to every piece of equipment on deck. When operators think about compliance and efficiency, attention naturally goes to engines, fuels and emissions systems. The equipment used for day-to-day cleaning and maintenance plays a bigger role in a vessel's overall performance and compliance record than it's often given credit for. Take something as ordinary as a tank or bulk cleaning kit. Poorly maintained or underpowered equipment means longer cleaning cycles, more chemical and water use, and more vessel downtime, all of which have knock-on effects for fuel efficiency and operating costs. It's a small link in the chain, but it truly is a real one. This is the thinking behind our Caretech range, from the HR/HP Kit with its telescopic lance to the Discharge Kit XXL for larger-scale jobs. These aren't just cleaning tools, they're engineered to reduce cycle times, cut resource use and hold up to the demands of continuous marine operation. For our customers, that translates into fewer hours lost to maintenance and a smaller footprint from routine operations most people never think to ask about. It's a good reminder that being "the right choice" as a supplier isn't only about the big-ticket compliance conversations. It's also about getting the everyday equipment right, consistently, across an entire fleet. **Did you know** that we produce our equipment in-house?

Here's how we make that work across six locations on four continents. --- # Global reach, one standard **Global reach, one standard** Global reach only matters if it comes with consistent quality. Here's how we make that work across six locations on four continents. For operators choosing a supplier of maritime products and services, reach and reliability tend to pull in opposite directions. A single local supplier can offer close relationships and fast response times, but only in one region. A large global player can cover every port an operator calls at, but often at the cost of consistency, with quality and service varying office to office. Marine Care is built around closing that gap. With offices spanning Bergen, Rotterdam, Singapore, Manila, Miami, and New Orleans, we cover the major trade routes and bunkering hubs our customers actually operate through, without asking them to manage a different relationship, different documentation standards or different service quality in every port. The combination of genuinely global coverage paired with a single, consistent standard of product quality and customer service is deliberate. We would argue that this is the real test of a maritime supplier in 2026. As compliance requirements multiply and supply chains get more complex, operators need fewer relationships to manage, not more, and they need to trust that quality doesn't change depending on which office picks up the phone. --- --- title: Building the infrastructure for cleaner bunkering url: "https://www.marine.care/news/building-the-infrastructure-for-cleaner-bunkering/" type: articles.ArticlePage published: 2026-08-24 updated: 2026-08-24 description: Behind every compliance deadline is a supply chain that has to actually work. Here's some insight on how we have built ours. --- # Building the infrastructure for cleaner bunkering **Building the infrastructure for cleaner bunkering** Behind every compliance deadline is a supply chain that has to actually work. Here's some insight on how we have built ours. Regulations set the targets. Infrastructure is what makes hitting them possible. That's the thinking behind two of our flagship projects: TIER III, our dedicated urea bunkering barge in Houston, and UREA-Xpress, our Rotterdam-based bunkering operation developed in partnership with Yara. Both projects exist to solve the same underlying problem from different sides of the Atlantic: as more vessels rely on SCR systems to meet NOx limits, urea can't be treated as an afterthought squeezed in around fuel bunkering. It needs dedicated vessels, reliable scheduling, and a supply partner who treats it with the same operational seriousness as fuel itself. The Yara partnership behind UREA-Xpress reflects that philosophy directly, pairing our bunkering and logistics expertise with Yara's position as a leading urea producer, so customers calling at Rotterdam get dependable access without having to coordinate multiple suppliers themselves. TIER III does the same job for the Gulf Coast, giving vessels calling at Houston a dedicated point of supply rather than a logistics puzzle. Projects like these are, in a sense, the quiet infrastructure work behind the headline regulations everyone talks about. They're also a good illustration of what we mean when we say we're built for the operational reality of compliance, not just the paperwork. --- --- title: What actually matters when choosing a marine chemicals supplier url: "https://www.marine.care/news/what-actually-matters-when-choosing-a-marine-chemicals-supplier/" type: articles.ArticlePage published: 2026-08-26 updated: 2026-08-26 description: With so many suppliers competing on price, it's worth asking what really separates a reliable partner from a risky one. --- # What actually matters when choosing a marine chemicals supplier **What actually matters when choosing a marine chemicals supplier** With so many suppliers competing on price, it's worth asking what really separates a reliable partner from a risky one. On paper, marine chemical products can look like a commodity. Urea is urea, a cleaning agent is a cleaning agent, so the temptation - especially under pressure - is to treat supplier choice as a straightforward price comparison. In practice, operators who've been caught out by a missed delivery window, an inconsistent product specification or a supplier who couldn't service a particular port know that it's rarely that simple. A few things tend to separate the suppliers worth building a long-term relationship from the rest; **Consistency across locations** A product that performs to spec in one port needs to perform exactly the same way in the next. That sounds obvious, but it's harder to guarantee than it looks once a supply chain spans multiple regions and sub-suppliers. **Documentation that holds up** As compliance reporting gets more demanding with emissions data, fuel- and chemical specifications or safety data sheets, a supplier who can't produce clean, consistent documentation on request becomes a liability, not a convenience. **Presence where it counts** Suppliers who only operate in a handful of major hubs force operators to juggle multiple relationships across their trade routes. A supplier with genuine reach removes this friction. **Responsiveness when something goes wrong** Every supply chain has disruptions. What really matters is whether a supplier has the infrastructure, flexibility and local knowledge to solve a problem quickly, or whether the operator is left waiting on an email from another time zone. None of this is new thinking, we know that. It's the same logic that applies to any critical supply relationship in shipping, but it's worth restating, because it's exactly the standard that we hold ourselves to across every product line and every office. Reliability isn't a marketing claim, it's something that either shows up in the delivery record or it doesn't. --- --- title: Going the extra mile - a delivery for Champion Pula url: "https://www.marine.care/news/going-the-extra-mile-a-delivery-for-champion-pula/" type: articles.ArticlePage published: 2026-09-07 updated: 2026-09-07 --- # Going the extra mile - a delivery for Champion Pula **Going the extra mile - a delivery for Champion Pula** When the vessel Champion Pula had an urgent need for eight drums of Xcellerate VO, standard delivery wasn't an option, the ship could only be reached by a small transport boat normally reserved for crew transfers. For our Rotterdam team, that wasn't a reason to delay. It was a logistics challenge to solve. The delivery required two separate trips by boat, with a Marine Care representative accompanying the cargo each time to ensure it arrived safely. Heavy barge traffic meant waiting for access to the vessel, and at one point the cargo had to be carefully transferred across another barge that was unable to move out of the way. In total, the operation took five hours from start to finish. It's the kind of situation that doesn't show up in a shipping schedule, but it's exactly where reliable support matters most. Our team adapted the plan in real time, coordinated the logistics on the ground and made sure the vessel received what it needed, on time and without compromise. For us, this is what customer support looks like in practice: not just fulfilling an order, but finding a way through when the standard route isn't available. It's a small story, but it reflects how we work every day, wherever our customers need us, however we need to get there. _Marine Care supplies marine chemicals and delivery support to vessels worldwide.

This is a reminder that clean combustion depends on more than clean fuel. Much of the industry conversation around decarbonization focus on alternative fuels, like methanol, ammonia and other substances. For the vessels running today and for years to come, one of the most immediate compliance tools is far simpler: urea, used in SCR systems to cut nitrogen oxide (NOx) emissions. This matters now more than ever. New emission control areas are entering this year, which tightens NOx and SOx limits in waters that many of our customers sail through regularly. For vessels fitted with SCR systems, reliable access to high-quailty marine urea is simply a must-have. This is where our dedicated bunkering infrastructure comes in. Through TIER III in Houston and UREA-Xpress in Rotterdam with our partnership with Yara, we've built supply points specifically so that operators can easily access urea supply in ports all around the world.

Over the last three decades, we have been in the forefront of tank cleaning in the maritime industry. In shipping, three decades means a lot of changes, but also doing some things the old fashioned way, while always improving for the better. We have been around long enough to see technology come and go, regulations tighten and expectations rise through the years. Tank cleaning on vessels has shifted from high-risk manual labor to more automated operations, while still demanding the expertise that come from years of real experience and being there for the tough challenges that can occur at any time. So - what has actually changed since we started this journey, and what can still be recognized today? **"If all you have is a hammer, everything looks like a nail"** Equipment has come a long way. Choosing the right set of tools for the cleaning job can in some cases make days of difference to finish the challenge. Where tank cleaning once relied heavily on manual methods and a fair amount of guessing, modern day equipment gives the crew far greater precision and control. Over the years, we have developed our equipment to fit our customer's wants and needs by listening and learning how to improve, while still being cost effective. Telescopic lances, high pressure cleaners and discharge kits allow for more thorough cleaning with less manual exposure and less time in confined spaces. With new and better innovations and investments comes more consistent results and safer operations. **Faster respond time supported by action** Our investments in TIER III, UREA-Xpress, our equipment center, laboratory and Research & Development center shows that we are committed to doing our part for a more sustainable world. Creating our own equipment and testing and improving our products in-house means shorter feedback loops between what we learn in the field and what we create for new product generations. This also means that we can respond faster when a customer's tank or cargo doesn't fit the standard case. Our team of experts are driven by new challenges and finding the best fit for your vessel's needs. **The bar keeps rising** Regulatory requirements around maritime cleaning have become stricter over the years, and rightfully so. Environmental standards, cargo compatibility rules and documentation requirements are more demanding now than when we started 30 years ago. Tough cleaning jobs require real chemical expertise and products that can prove their performance. Luckily, you know where to find them. **So - what hasn't changed?** Behind all the regulatory changes and the continuous demands for a more sustainable operation, one thing still remains at the core of what we do - getting a tank or cargo properly clean, safely and on schedule. This fundamental responsibility is exactly why we started our business 30 years ago, and it's still what drives us today. Our care for our customers is still the same, just with some better tools, sharper science and higher standards.

Skimping on the right products is one of the most expensive corners a vessel can cut, and the bill often shows up in places you wouldn't expect. --- # What bad fuel treatment can cost you **What bad fuel treatment can cost you** Fuel treatment rarely gets the attention it deserves. Skimping on the right products is one of the most expensive corners a vessel can cut, and the bill often shows up in places you wouldn't expect. **Engine damage adds up fast** Untreated or poorly treated fuel brings water, sediment and microbial growth straight to your vessel's fuel system. Over time, this leads to clogged filters and corrosion inside tanks and pipework. What starts as a maintenance issue can escalate into major engine damage. **Downtime is a silent cost** A vessel that isn't moving, isn't earning. Fuel-related breakdowns is not just costing money in repairs, they also cost money in missed schedules, delayed cargoes and disrupted charters. A few hours of downtime can easily outweigh the cost of proper fuel treatment for months to come. **Compliance risk is real** With fuel quality regulations tightening, off-spec or poorly treated fuel can put a vessel at risk of non-compliance, and the penalties for that goes well beyond a fine. Detentions, reputational damage and demands from port authorities are real possibilities when fuel quality isn't managed properly. **The fix costs less than the failure** High quality fuel treatment is not a complicated matter, and not really an expensive one either. Regular water removal, biocide treatment where needed and fuel conditioning are straightforward measures that protects the engine, keep vessels compliant and most importantly; it keeps them sailing. We've spent years helping vessel operators avoid exactly these kind of costs. When it comes to fuel treatment, the slightly more expensive option today might just be what saves your money in the future. We offer a complete range of fuel oil treatment chemicals, test kits and equipment designed to help operators get the most from every tonne of fuel. _Contact us today_ and we will help you in choosing the right kind of solutions for your fleet. --- --- title: "Meet our people: Yiannis Zavitsianos" url: "https://www.marine.care/news/meet-our-people-yiannis-zavitsianos/" type: articles.ArticlePage published: 2026-10-06 updated: 2026-10-06 --- # Meet our people: Yiannis Zavitsianos **Meet our people: Yiannis Zavitsianos** **Building Partnerships Across the Cruise Industry** If you've ever wondered what it takes to supply some of the world's largest cruise operators, Yiannis has a simple answer: _Relationships_. As Regional Vice President of Marine Care Americas and the Cruise Services in Florida, Yiannis has spent more than a decade helping build Marine Care's presence in the Americas. Today, his team supports major cruise operators across the region, but the journey started with a much smaller operation and a lot of persistence. "When I joined, most customers still knew us as a ship chandler that sold some chemicals on the side. We had to prove ourselves product by product, customer by customer." That process took years, but it laid the foundation for what Marine Care Cruise Services has become today. **From Local Supplier to Trusted Partner** When Yiannis joined the business in 2011, Marine Care's operation in Florida looked very different than it does today. At the time, the company was still transitioning from a traditional ship supply business into the specialist chemical and technical services partner it is known as today. A major breakthrough came when Marine Care was given the opportunity to support Royal Caribbean with water treatment chemicals. As confidence grew, so did the relationship. More products were added. More vessels were supported. More opportunities opened up. Over time, similar success followed with other cruise operators, helping establish Marine Care as a trusted partner within the industry. Looking back, Yiannis is most proud of one thing. "We've built a reputation as a highly reliable business partner. Our customers know they can pick up the phone any day of the week, any day of the year, and someone from Marine Care will do everything possible to help them." **Understanding the Customer's World** One thing becomes clear when speaking with Yiannis: success in the cruise industry is about much more than products. It starts with understanding how customers operate. Cruise ships run on strict schedules. Every delivery matters. A delayed shipment can affect operations, guest experiences and, in some cases, thousands of passengers onboard. Yiannis recalls one example that many people outside the industry would never think about. If a vessel runs out of water treatment chemicals and cannot maintain its pools and jacuzzies, those facilities may need to be closed. That might sound like a small issue, but for a cruise operator it can quickly become a major customer experience problem. "You're not just delivering chemicals. You're helping keep part of the guest experience running. If something critical doesn't arrive on time, the impact can reach far beyond the engine room." Understanding these realities helps Marine Care anticipate challenges before they become problems. **The Human Side of Business** Despite operating in a highly technical industry, Yiannis believes the most important part of business is still people. Technology continues to evolve. Processes become more automated. Communication becomes increasingly digital, but relationships remain at the center of everything. "The stronger the relationship, the stronger the trust. Once you move beyond emails and start having real conversations, that's when things begin to grow." For Yiannis, building relationships means understanding how customers work, what they care about and what success looks like for them. It also means being available when they need support. This philosophy has helped Marine Care establish long-term partnerships with some of the world's most recognized cruise brands. **Looking Ahead** The cruise industry continues to grow, with new vessels, new technologies and increasing focus on sustainability. For Marine Care, that creates exciting opportunities. Whether it is helping customers improve water treatment, supporting environmental initiatives or developing new solutions for specific operational challenges, Yiannis sees plenty of room for growth in the years ahead. His ambition is simple. "All we need is the opportunity to prove ourselves. Once customers see what we're capable of, the relationship can grow from there."

That's why we continuously work towards finding smarter and more conscious ways to drive the company forward. Our goal is to make sustainability a natural part of everything we do, from small, everyday choices to bigger and more strategic decisions. ![We Care](https://media.marine.care/original_images/e21bb22e-8c91-44ed-8238-bbd4523ff009.png) ## Environment Marine Care has a fundamental duty of care for the global environment as one of its core visions.

The fluid may be used only on austenitic stainless steel as it corrodes other materials. It removes welding slag, annealing scale, grinding dust and iron parts etc. If left untreated the free iron particles will cause corrosion of austenitic stainless steel. ## Advantage Careclean Pickling Liquid is blended under controlled and stable circumstances minimizing the dangers of onboard mixing. ## Applications Careclean Pickling Liquid is used mainly for pickling installations, tanks and pipework. It may be used by means of circulation, spraying or in immersion baths. Before commencing, make sure the surfaces are thoroughly cleaned and degreased, free of any organic material that could react with Careclean Pickling Liquid. Well cleaned and degreased surfaces, will result in a uniform pickling job. Use Careclean ECS Quick Dry to remove felt pen ink- marks. Careclean Alkaline is used for degreasing small metal surfaces. To degrease tanks we advice the use of a 1 - 2 % solution of Careclean GP Enviro or Multiclean in warm water. After pre-cleaning rinse thoroughly with a waterjet to remove any degreaser residues. ### Reciculation Method This method is used mainly for cargo tank pipingsystems. Fill the system with cold undiluted Careclean Pickling Liquid. Pickling will take 2 to 6 hours depending on the degree of discoloration and on the sort of austenitic steel. Drain the system and rinse carefully, preferably with demineralized water. An introduction of chlorides being present in ordinary water will cause instant corrosion as the protective passive layer of the austenitic stainless steel has been removed after the use of Careclean Pickling Liquid. After rinsing with demineralized water passivation should follow immediately. Passivation is conventionally done by ambient air (24 hours as a minimum), but to speed up this process or if there is insufficient air flow, like in cargo tanks or lines, liquid passivation must follow. Careclean Passivation Liquid has to be used. ### Spray Method Careclean Pickling Liquid is sprayed undiluted on the stainless steel. Leave to react for 30 minutes or as long as necessary for a good result. The liquid should in any case not dry before rinsing. After pickling rinse thoroughly with demineralized water. After rinsing the surfaces must be passivated. ### Passivation A protective chromiumoxide layer will be formed on the austenitic stainless steel only if oxidizing conditions are present. For example during long term rinsing with cold water (below 25 ˚C) or during storage in the open air. Under these circumstances the stainless steel automatically passivates. The time for passivation has to be 24 hours as minimum. In case there is lack of time we recommend passivation with Careclean Passivation Liquid, particularly if the stainless steel is exposed to corrosive conditions soon after pickling. Good results are obtained if the object is sprayed/brushed with Careclean Passivation Liquid immediately after it has been well rinsed. Five minutes after applying Passivation Liquid rinse with plenty of DI water. ## Dosage | Method | Dosage | | ------------- | --------- | | Spraying | undiluted | | Recirculation | undiluted | ## Properties | Article number | 14610 / 16610 | | -------------- | ------------- | | pH | 1 | | Density | 1,10 g/cm^3^ | | Flashpoint | None | | Physical state | Liquid | ## Safety Careclean Pickling Liquid contains nitric acid and hydrofluoric acid.

The Caretech D.I. water units are available in 3 sizes: - Caretech MC-40 - up to 750m³ capacity - Caretech MC–75 - up to 1400m³ capacity - Caretech MC-103 - up to 1918m³ capacity Als units are available as single version or twin set for mobile use. If required, Marine Care can also assemble the filters in a (fully automated) skid that can be fixed on board. **Single use:** Incoming water only passes 1 filter. Once this filter is up for replacement, the second filter is taken in use. This is advised for combination with treatment of evaporator water, which already has a low conductivity. **Twin set, connected in series:** Incoming water first passes 1 filter, then passes on to the second one for double polishing. This is advised when incoming water quality has a high conductivity (500 – 750μS/cm) or if DI water needs to be extremely pure (< 0,5ppm chloride). Please note that the total capacity is about 10% below the theoretical capacity of 2 individual filters. Once the first filter is up for replacement, the second filter can be used as first filter in the new setup. ## Each Unit Comes With - Mixed bed resin for refill available in all main ports - Hoses & connectors - Conductivity meter to check performance (twin set only) - Filling funnel (twin set only) ## Important for All Caretech DI Units The maximum recommended working pressure is 8 bar (120 psi). This filter is designed for a maximum working pressure of 10 bar (150 psi). The system has to be frost protected. Temperature range 1 °C – 50 °C. Spare resin can be stored between minus 10 °C – 60 °C. The mixed bed resin is a polishing resin, to produce ultra pure water from evaporator water as supply. Check the output water quality frequently with the supplied conductivity meter! The maximum allowable conductivity is 750 μS/cm. The pureness of the produced water depends on the supplied water quality and the flow velocity through the filter. Install a pressure relief valve in your system if there is no effective control of maximum line pressure. **Datasheet**: [Caretech-DIunits](https://www.marine.care/documents/290/Caretech-DIunits.pdf) --- --- title: Careclean Potassium Hydroxide (KOH) url: "https://www.marine.care/products/careclean-potassium-hydroxide/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-15 description: Concentrated Potassium Hydroxide which can be used to boost cleaning solutions or as a stand alone cleaning solution categories: - Tank cleaning - Hold cleaning - Raw Materials --- # Careclean Potassium Hydroxide (KOH) **Categories**: [Tank cleaning](/product-categories/tank-cleaning/) · [Hold cleaning](/product-categories/hold-cleaning/) · [Raw Materials](/product-categories/raw-materials/) - **Document number**: PDS-08-145 - **Revision**: 3.0 - **Revision date**: 2023-11-29 - **Language**: EN ## Description Careclean Potassium Hydroxide is concentrated Potassium Hydroxide in solid form.

Careclean Pickling Paste contains nitric and hydrofluoric acid. ## Advantage Careclean Pickling Paste is easy to apply due to its gelly nature, even on vertical welding seams and surfaces. ## Applications Careclean Pickling Paste is used for pickling of welding seams and surfaces of austenitic stainless steel in any kind of construction, such as: tanks, pipes, frames, etc. Metals other than austenitic stainless steel will be corroded by the strong pickling effect of the product. Nickel, nickel-alloys and copper-nickel-alloys may also be pickled with Careclean Pickling Paste (always test first!). ### Directions for use ### Pretreatment The surfaces should be pre-cleaned with an alkali waterbased degreaser as: Careclean GP Enviro or Multiclean. After pre-cleaning rinse with plenty of freshwater. Allow the surface to dry. ### Pickling Please read the security instructions before you start pickling. During storage the paste may become partially liquid. Mix the Careclean Pickling Paste, using a plastic or wooden stirring rod. Brush the paste on the surfaces and welds in a closed thick layer, with an acid resistant brush. After brushing, clean the brush thoroughly with freshwater and allow to dry. The Careclean Pickling Paste is applied at temperatures from 10 to 25 ˚C. The product should not be applied in bright sunlight or windy conditions. Allow the pickling paste to act for 15 - 60 minutes on austenitic stainless steel, 5 - 20 minutes on nickel, nickel-alloys and copper-nickel-alloys. In case pickling has not been sufficient, then rinse and re-pickle. For a temperature change of 10 ˚C up or down from 20 ˚C , the pickling activity and thus the pickling time changes roughly by a factor two. Normally it is sufficient to let the Careclean Pickling Paste act for the given time without further mechanical action. In case the welds are uneven, it may be necessary to rub the welds with a Scotch Brite pad. The Pickling Paste should still be active. ### Rinsing after pickling Remaining Pickling Paste must be removed completely by thoroughly rinsing. Primarily, remaining paste can be removed with rags or tissues. Rinsing should be done with a high pressure cold water jet of at least 50-60 bar. If a high pressure water jet is not available, rinsing with a water hose assisted by brushing or rubbing with a Scotch Brite pad. Nickel, its alloys and copper-nickel alloys have to be rinsed and cleaned thoroughly after pickling. The chloride contents of the rinsing water should be as low as possible. If possible, use demineralized water. ### Passivation A protective chromium oxide layer will be formed on the austenitic stainless steel only if oxidizing conditions are present. For example during long term rinsing with cold water (below 25 ˚C) or during storage in the open air. Under these circumstances the stainless steel automatically passivates. The time for passivation has to be 24 hours as minimum. In case there is lack of time we recommend passivation with Careclean Passivation Liquid, particularly if the stainless steel is exposed to corrosive conditions soon after pickling. Good results are obtained if the object is sprayed/brushed with Careclean Passivation Liquid immediately after it has been well rinsed. Five minutes after applying Passivation Liquid rinse with plenty of DI water. ## Dosage *Dosage* - Brushing - Undiluted ## Product Consumption *Product Consumption* | Welds | 75 - 150 | m per kg | | -------- | -------- | --------- | | Surfaces | 4 - 8 | m² per kg | ## Properties *Properties* | Article number | 14612 | | -------------- | -------------------- | | pH | 1,2 ( 1 % solution ) | | Density | 1,2 g/cm^3^ | | Flashpoint | None | | Physical state | Gelly Liquid | ## Safety Careclean Pickling Paste contains nitric acid and hydrofluoric acid.

Careclean Voyage is used for removing heavy crude oil, asphalt and carbon black stains, by direct injection, "Voyage method", spraying and/or recirculation. ## Advantage - Highly concentrated - Non caustic - Safe on most common metals - Applicable at low temperatures - Safe on:Most common metalsZinc, epoxy and polyurethane coatings - Approved by:IMOMarinflocCoating Manufacturers ## Application ### Tanks Careclean Voyage can be used for the removal of most mineral oils and fats in cargo and storage tanks. ### Double Bottom Tanks Careclean Voyage can be used for cleaning and gas freeing of double bottom tanks, using the rolling motion of the ship which normally provides sufficient agitation. ### Cleaning of cargo and storage tanks ### Prewash Before cleaning with Careclean Voyage, it is recommended to prewash tanks with hot water of approximately 50 °C, except for crude oil, drying and semi‑drying oils where a prewash with cold water should be applied. ### Direct Injection Method For Cargo Tanks Undiluted Careclean Voyage should be injected at a predetermined rate into the pressure side of the automatic tank cleaning system line on deck, by means of an air operated drum pump. Usually an injection rate of 0.1 - 0.2 % of Careclean Voyage is sufficient. Cleaning time 2-6 hours. Subsequently rinse with water. ### Hand Spraying Method Spray undiluted Careclean Voyage directly on to bulkheads, frames, stringers etc. using an air operated drum pump complete with a discharge hose and a hand spray gun. After a pre-determined reaction time, tanks should be rinsed with water using the automatic tank washing machines. For spot cleaning only use a hose for rinsing, for example a fire hose with nozzle. Hand spraying method is the most economical way in terms of chemical consumption but requires tanks being gas-free, enabling men to enter tanks. However, hand spraying method has a practical time limitation depending on tank sizes, i.e. total tank surface to be sprayed. ### Recirculation method A chemical solution is prepared in one of the after tanks near the pump room and is circulated by the automatic tank washing system's pump and heater to the tank to the cleaned. The solution is returned to the chemical solution tank via the stripping line. Usually it is not possible to recirculate solution over the tank washing system's heater (to maintain solution temperature) without making a temporary connection between the chemical solution tank and the tank washing pump. The capacities of the solution tank, pipelines and pumps etc. should be calculated carefully, to ensure sufficient volumetric quantity for a continuous recirculation. Depending on the size and the condition of the tanks to be cleaned and quantity of chemical solution, usually up to three tanks can be cleaned with one solution. To continue cleaning of other tanks a fresh solutions has to be prepared. Careclean Voyage is circulated in a 2 - 6 % solution in seawater. After chemical cleaning the tanks should be rinsed thoroughly with seawater or fresh water, depending on availability and requirements. ### Voyage Cleaning Method: (Double Bottom Tanks) _Tank_ Time, temperature and agitation of chemical solution are important factors for the successful cleaning of Double Bottom. _Note_ If the tanks are not severely contaminated and/or the fuel-oil viscosity is lower than 180 cSt at 50 °C the cleaning process should be in one stage using step 5 - 10 only. 1. Heat the tank to a higher than normal temperature, pump out as much fuel as possible and trim the vessel to ensure complete stripping. 2. Close all valves on the engine room manifold. 3. Introduce the first dose of Careclean Voyage, through the sounding pipe, in accordance with the dosage table stated below and fill the tank to 25 % of its capacity with sea water. For filling the tanks it is to be advised, not to use the ballast lines, as they may contain fuel-oil making the cleaning more difficult. 4. Heat the cleaning solution to a minimum of 60 °C and maintain this temperature for 48 hours. If heating coils are not available, live steam may be used for heating the solution and maintain the temperature. 5. Empty the tanks completely, fill to 50 % capacity and empty again. Where single stage cleaning is used the previous steps are ignored. 6. Add a second dose of Careclean Voyage and fill the tank with sea water to 50 % of its capacity, continue heating and maintain at this level for 48 hours. 7. Add further sea water to fill the tank to 75 % capacity, continue heating and maintain for another 48 hours. 8. Empty the tanks and pressure rinse with clean water through the sounding pipes for 1 - 2 hours under continuous stripping. The pressure should be kept as high as safety permits. 9. When rinsing is completed stop the discharge (stripping) pump and fill the tank until clear water runs from sounding pipes on deck. 10. Stop the water supply and empty (strip) the tank. Trim the vessel to ensure complete stripping. ## Dosage *Dosage summary* | Method | Dosage | | ---------------------- | ---------------- | | Direct Injection | 0,1 - 0,2 % | | Recirculation | 2 - 6 % | | Hand spraying | undiluted | | Voyage Cleaning Method | see dosing table | *Dosage of Careclean Voyage in liters per tank* | Tank capacity in tons | Dosage of Careclean Voyage in liters per tank | Dosage of Careclean Voyage in liters per tank | Dosage of Careclean Voyage in liters per tank | | --------------------- | --------------------------------------------- | --------------------------------------------- | --------------------------------------------- | | Tank capacity in tons | Minimum | Normal | Maximum | | 2-5 | 2 | 4 | 6 | | 5 | 4 | 8 | 12 | | 10 | 8 | 16 | 24 | | 15 | 12 | 24 | 36 | | 20 | 16 | 32 | 48 | | 25 | 20 | 40 | 60 | | 30 | 24 | 48 | 72 | | 40 | 32 | 64 | 96 | | 50 | 40 | 80 | 120 | | 75 | 60 | 120 | 180 | | 100 | 80 | 160 | 240 | | 200 | 160 | 320 | 480 | | 250 | 200 | 400 | 600 | | 300 | 240 | 480 | 720 | | 400 | 320 | 640 | 960 | | 500 | 400 | 800 | 1200 | | 600 | 480 | 960 | 1440 | | 700 | 560 | 1120 | 1680 | | 800 | 640 | 1280 | 1920 | | 900 | 720 | 1440 | 2160 | ## Properties | Property | Value | | -------------- | -------------- | | Article number | 14607 / 16607 | | pH | Not applicable | | Density | 0,88 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals - IMO approved in accordance with MEPC 590 Guidelines - Marinfloc Approved OWS Compatible - Major coating manufacturers.

Due to ships sailing on reduced speed in combination with low fuel quality the amount of soot in the exhaust gas has increased. Because of the low gas flow, the soot particles can easily settle on the heat exchanger fins. This results in decreasing exhaust gas boiler efficiency and decreasing engine efficiency. Caretreat Economizer prevents low temperature corrosion by neutralizing sulfuric acid. ## Advantages - Complete coverage of entire exhaust gas system - Improved exhaust gas boiler and engine efficiency - Neutralizes sulfuric acid - Prevents low temperature corrosion LTC - Reduces fire risk in the exhaust gas boiler - An easily dosed liquid ## Application Caretreat Economizer is a specially developed liquid which is easily dosed into the system, using a special Marine Care injection unit. The air assisted nozzles create a fine mist. The liquid vaporizes on contact with the hot exhaust gas. The exhaust gas temperature should be above 200 ˚C. The active material reacts with the soot particles to create light, dry and non-adherent soot particles that easily pass the heat exchanger in the exhaust gas boiler. The resulting deposit is friable and can be easily removed by conventional soot blowing. ## Directions for Use In case the exhaust gas boiler is heavily fouled, water wash the heat exchanger with an alkali solution, for example Careclean Alkaline or Alkaline Extra. Caretreat Economizer is injected undiluted, with an air assisted nozzle down stream in the exhaust gas line direct after the turbo charger discharge. ## Injection Systems _Marine Care_ offers a complete range of EGT Exhaust gas treatment dosing systems customized for your engine type. ## Dosage Daily 1 - 2 liters per 1000 m^2^ of exhaust gas boiler heat exchanger surface. ## Properties | pH (1 % solution) | 7 | | ----------------- | -------------- | | Density | 1,31 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-22 Caretreat Economizer - rev. 3 251018](https://www.marine.care/documents/93/PDS-08-22_Caretreat_Economizer_-_rev._3_251018.pdf) --- --- title: Caretreat Combustion url: "https://www.marine.care/products/caretreat-combustion/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Combustion improver for treatment of heavy/high, low and very low sulphur marine fuel oil categories: - Fuel Treatment --- # Caretreat Combustion **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-20 - **Revision**: 2.0 - **Revision date**: 2023-07-14 - **Language**: EN ## Description Caretreat Combustion is a concentrated in oil soluble and self dispersing fuel oil treatment primarily formulated to combat problems in the combustion and post combustion stage on heavy fuels used in marine diesel engines and boiler plants. ## Advantages - Increases combustion efficiency - Reduces carbon built-up effectively in combustion zones - Inhibits the formation of carbonaceous ash deposits in exhaust and scavenging ports - Minimizing low temperature corrosion by effective catalysts inhibiting conversion of sulfur dioxide to sulfur trioxide - Reduces piston ring groove and piston fouling resulting in longer life of piston rings and cylinder liners - Reduces ash deposit formation in turbo-chargers and on exhaust valves - Decreases smoke emissions - Fuel conditioning components stabilizes fuel viscosity, preventing sludge formation in tanks, filters, pre-heaters - Improves water separation in settling tanks and separators ## Application Caretreat Combustion should be dosed via a metering pump into the suction side of the fuel transfer pump. Alternatively the product can be mixed in the settling tank. To treat the fuel for the oil fired boiler, the product should be dosed by a metering pump into the burner feed line. ## Direction for Use/Dosage Dosage rates depend upon engine characteristics, operating conditions and quality of fuel oil. A CCAI number (Calculated Carbon Aromaticity Index), is an index of the ignition quality of residual fuels. Exceeding 840 indicated a poor fuel oil quality which justifies the use of a chemical fuel oil treatment to counteract the effects. Typical dosage rates are 1:1000, 1:6000 and 1:12000. Consult your local Marine Care Service Engineer for recommendations of the dosing rate, based on specific problems and requirements onboard. ## Injection Systems _Marine Care_ offers a complete range of fuel treatment dosing systems. ## Properties | Property | Value | | -------------- | -------------- | | pH | Not applicable | | Density | 0.85 g/cm^3^ | | Flashpoint | 63 ˚C | | Physical state | Liquid | ## Health & Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-20 Caretreat Combustion - rev. 2 140720](https://www.marine.care/documents/91/PDS-08-20_Caretreat_Combustion_-_rev._2_140720.pdf) --- --- title: Caretreat FOT LS url: "https://www.marine.care/products/caretreat-fot-ls/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Fuel conditioner improving lubricity in low sulfur marine diesel fuels, preventing injector and fuel pump wear, deposits, and corrosion categories: - Fuel Treatment --- # Caretreat FOT LS **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-23 - **Revision**: 1.0 - **Revision date**: 2018-10-25 - **Language**: EN ## Description Caretreat FOT LS is a fuel conditioner which improves the lubricity in low-sulfur diesel fuels with poor lubricity characteristics. The blend of dispersants, surfactants, detergents and lubricity improvers prevents wear of metal to metal contact surfaces in injectors and high pressure fuel pumps and prevents fuel instability. ## Advantages - Fuel injector wear is strongly reduced - Fuel pump plunger wear and sticking is avoided - Carbon and fuel system deposits are prevented - Fuel ignition quality is improved - Visible smoke opacity and soot fouling is reduced - Enhanced corrosion protection ## Application Caretreat FOT LS can be added to the low sulfur bunker tank prior to bunkering fuel oil. The required amount is introduced into the bunker tanks simply by pumping it in to the sounding pipes or by metering pump into the bunker manifold. The turbulence created by the subsequent bunkering will, together with the incorporated dispersants, ensure complete mixing and further distribution of the treatment uniformly throughout the fuel. The product can also continuously be dosed by a metering pump into the suction side of the booster pump. ## Direction for Use/Dosage To obtain the benefits of the chemical treatment in the entire fuel oil system it is necessary to dose the product in the most appropriate ratio depending upon the nature and severity of the problem. The dosage of Caretreat FOT LS varies depending on the fuel grade & performance targets to be met. The fuel oil should be sampled and analyzed on a regular basis to monitor its quality. For low sulfur diesel fuel ( < 500 ppm Sulfur): - Caretreat FOT LS should be dosed at 1:5000 - Dosage might have to be raised in case of residual fuel oil to 1:3000 Fuel oils containing more than 500 ppm Sulfur do not require treatment for lubricity improvement. ## Injection Systems _Marine Care_ offers a complete range of fuel treatment dosing systems. ## Properties | pH | Not applicable | | -------------- | -------------- | | Density | 0,93 g/cm^3^ | | Flashpoint | 85 ˚C | | Physical state | Liquid | ## Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-23 Caretreat FOT LS - rev. 1 251018](https://www.marine.care/documents/90/PDS-08-23_Caretreat_FOT_LS_-_rev._1_251018.pdf) --- --- title: Caretreat Sludge url: "https://www.marine.care/products/caretreat-sludge/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Pre-combustion fuel treatment for residual heavy fuels categories: - Fuel Treatment --- # Caretreat Sludge **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-26 - **Revision**: 1.0 - **Revision date**: 2018-10-25 - **Language**: EN ## Description Caretreat Sludge is an oil soluble and self dispersing fuel oil treatment primarily formulated to combat problems in the pre-combustion stage on heavy fuels used in marine diesel engines and boiler plants. ## Advantages - Dissolves and disperses existing sludge. Dispersants maintain the combustible constituents in suspension throughout the fuel - Prevents polymerization and inhibits asphaltic sludge formation and paraffin wax separation, resulting in less clogging of fuel filters and less fouling of fuel injectors - By dispersion of sludge, Caretreat Sludge will counteract the effects of layering of incompatible fuels, thereby promoting a homogenous uniform viscosity - Will break water/oil emulsions and promote separation of dispersed water from heavy fuel oil, thereby improving the purifier efficiency - Corrosion in tanks and fuel lines is reduced by the corrosion inhibitors in the product - Improved conditions in the pre-combustion stage will result in an improvement in the post combustion stage, as: a more complete combustion, less carbon formation, a decrease in deposit forming sodium and less smoke and soot ## Application Caretreat Sludge is easy to use. The required amount is introduced into the bunker tanks simply by pumping it into the sounding pipes prior to oil bunkering or dosing in the bunker manifold. The turbulence created by the bunkering ensures complete mixing and further distribution of the treatment uniformly throughout the fuel. ## Direction for Use/Dosage To obtain the benefits of the chemical treatment to the entire fuel oil system it is necessary to dose the product in the most appropriate ratio depending upon the nature and severity of the problem. If Caretreat Sludge is not used regularly an initial dosage of 1:4000 should be used for breaking up and dispersing existing sludge. For counteracting the effects of incompatible fuels (stratification) a dosage as high as 1:2000 may be necessary. ## Injection Systems _Marine Care_ offers a complete range of fuel treatment dosing systems. ## Properties | Article number | 14501 | | -------------- | -------------- | | pH | Not applicable | | Density | 0,89 g/cm^3^ | | Flashpoint | 85 ˚C | | Physical state | Liquid | ## Approvals For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-26 Caretreat Sludge - rev. 1 251018](https://www.marine.care/documents/96/PDS-08-26_Caretreat_Sludge_-_rev._1_251018.pdf) --- --- title: Caretreat Bacteria url: "https://www.marine.care/products/caretreat-bacteria/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Microbiological control agent for use in lube oil, fuel oil and diesel cooling water systems categories: - Fuel Treatment --- # Caretreat Bacteria (Fuel Treatment) **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-19 - **Revision**: 3.0 - **Revision date**: 2024-01-29 - **Language**: EN ## Description Broad spectrum microbiological control agent including bio-dispersants for growth protection in lube oil, fuel oil and cooling water systems. ## Advantages - Effective against bacteria and algae in oil and contaminated water - Special surface active component ensures complete coverage over large areas - Easy to use liquid ## Application Caretreat Bacteria is used in oil storage facilities and cooling water systems which have problems due to bacteria colonization and/or algae. Caretreat Bacteria is ideally suited for the treatment of Marine Diesel Engine Cooling Water Systems which have bacteria and/or algae infection. Diesel Cooling Systems have been prone to this, due to the common occurrence of lubricating and/or fuel oil and fatty exhaust gasses, mixing with cooling water. This gives an oil/water phase ideal for bacteria to colonize rapidly. Water containing bacteria leaks into the lube oil system due to faulty glands, joints and seals or during routine maintenance. Small amounts of infested water/oil sludges in the storage and circulatory parts of the lube oil system can quickly lead to major failure of bearing surfaces due to acidic conditions and degradation of the oils lubricating properties. ## Directions for Use ### Treatment of lube oil systems After serious contamination, all areas possible should be cleaned manually to remove sludge and slime. On large engines, cleaning with undiluted Careclean Degreaser HD Split of the casing frame, followed by opening and thoroughly cleaning the sumps is strongly recommended. This should be followed by flushing the entire lubricating oil system with a flushing oil containing 500 - 700 ml of Caretreat Bacteria per m^3^. ### Treatment of fuel storage tanks The action of bacteria in fuel during storage is widely underestimated. Problems of stratification of blended fuels is often allocated to incompatibility in stead of to bacteria. If bacteria are suspected, water drawn from the fuel storage tank drains should be tested with the Marine Care “Dip Slide Test” If bacteria are present (bacteria count above 10^5^ CFU/ml) treat the fuel with 700 - 1000 ml of Caretreat Bacteria to each m^3^ of fuel. ### Treatment of the coolingwater system(s) The system should be drained and refilled with fresh water treated with Caretreat Bacteria at 500-700 ml per m^3^ of water. Let the Caretreat Bacteria react for 48 hours whilst circulating with all coolingwater pumps. The engine should not be running. During this operation, careful attention should be taken to blanked pipes and bypass loops, etc., to ensure that these areas also receive adequate treatment. After 48 hours, drain the system as quickly as possible through all outlets. Refill the system with distilled water and add Caretreat 2 Diesel to give the correct corrosion inhibition levels and add 500 ml Caretreat Bacteria per m^3^. The product is not to be used in potable water systems. ## Dosage See Direction for Use. Caretreat Bacteria can also be dosed as a prevention aid at 250 -350 ml/m^3^ per m^3^ of fuel/lube oil. ## Health & Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. ## Note **Note:** The product may only be used on vessels sailing under foreign flag. **Datasheet**: [PDS-08-19 Caretreat Bacteria - rev. 3 290124](https://www.marine.care/documents/88/PDS-08-19_Caretreat_Bacteria_-_rev._3_290124.pdf) --- --- title: Caretreat EB url: "https://www.marine.care/products/caretreat-eb/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Water in oil emulsion breaker used to optimize the fuel separation system on board ships categories: - Fuel Treatment --- # Caretreat EB **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-21 - **Revision**: 3.0 - **Revision date**: 2018-10-25 - **Language**: EN ## Description Caretreat EB (Emulsion Breaker) is a newly developed water in oil emulsion breaker.

The product can be applied to all type of oil fired boilers. The components in the product will vaporize by the combustion heat. The vapor will create a reaction with sulfur to sulfurdioxide. Sulferdioxide leaves the boiler with the exhaust gasses, not being able to form sulfertrioxide what can condensate at the low temperature parts to form the highly corrosive sulfuric acid. The modified sulfur oxides combined with vanadium complexing compounds prevent the formation of harmful low melting point sodiumvanadylvanadates. Caretreat Soot acts as well as a catalyst, by lowering the ignition temperature of the soot particles. ## Advantages - Reduces soot and ash deposits - Eliminates the risk of hazardous soot fires - Prevents sulfuric acid forming, reducing the risk of corrosion - Induces fuel efficiency - Increases heat transfer resulting in better boiler efficiency - Minimizes cleaning and maintenance cost ## Application Caretreat Soot is a specially developed powder what is easily dosed into the system, using the Marine Care Air assisted powder injector. The powder vaporizes on contact with the hot exhaust gas. The combustion temperature should be far above the products sublimation point of 350 ˚C. The active material reacts with the soot particles to create light, dry and non-adherent soot particles that easily pass through heat exchangers and stack. The remaining deposit is friable and can easily be removed by conventional soot blowing. ## Directions for Use ### Dosage Initial dosage for fouled boilers should start at 130 grams per m³ fuel burnt in 24 hours. The calculated dose should be divided into 3 equal parts and dosed at 8 hour intervals. As conditions improve, the dosage can be progressively reduced to a minimum of 30 grams per m³ fuel burnt in 24 hours. Once every 24 hours soot should be blown at least 1 hour after the last injection of Caretreat Soot. If a boiler has never been treated and is highly contaminated, double the initial figures. This dosing regime can be applied for the first 2 weeks. ### Injection Systems An air operated powder injector can be supplied by Marine Care. Its discharge tube should be mounted through a combustion chamber sighting orifice or a special dosing access point. If possible, the injection should be changed frequently to assist distribution throughout the boiler. ## Dosage See Direction for Use ## Properties | pH | Not applicable | | -------------- | -------------- | | Density | 1,56 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Powder | For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-25 Caretreat Soot - rev. 2 251018](https://www.marine.care/documents/95/PDS-08-25_Caretreat_Soot_-_rev._2_251018.pdf) --- --- title: Caretreat Valves url: "https://www.marine.care/products/caretreat-valves/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Post-combustion fuel ash modifier to reduce high temperature corrosion categories: - Fuel Treatment --- # Caretreat Valves **Categories**: [Fuel Treatment](/product-categories/fuel-treatment/) - **Document number**: PDS-08-24 - **Revision**: 1.0 - **Revision date**: 2018-10-25 - **Language**: EN ## Description Caretreat Valves prevents for high temperature corrosion and fouling due to vanadium and sodium in the fuel. During combustion, these elements oxidize and form semi-liquid and low melting salts (vanadium pentoxide), which adhere to exhaust valves and turbochargers. In practice, the extent of hot corrosion and fouling are generally maintained at an acceptable level through temperature control, an operational solution, and material selection. In addition, Caretreat Valves has been developed to control the formation of these salts. Vanadium pentoxide has a melting point of 670 ˚C and is corrosive in a liquid state. Caretreat Valves reacts with vanadium oxides resulting in higher melting points, over 1.100 ˚C. The combustion process of these components results in a relatively harmless ash. ## Advantages - Reduces deposits caused by combinations of sodium, vanadium and sulfur in combustion zones, turbochargers and especially on exhaust valves - Increasing exhaust valve life substantially - Raising fuel ash sinter and melting point temperatures above the normal engine operating temperatures - Reduces turbocharger fouling - Reduces high temperature fused salt corrosion of valve alloys - Modifying vanadium compounds to non-adherent ash forms ## Application Caretreat Valves has been formulated primarily for use in 2-cycle and 4-cycle medium speed diesel engines which are highly turbocharged and in which premature exhaust valve failure is a frequent problem. ## Directions for Use The dosing point location varies depending on engine fuel system's layout. The most efficient and economical dosing method is obtained with a metering pump, dosing the additive for example in the suction side of the booster pump. Dosing rates are depending upon engine characteristics, operating conditions and especially the quality of the fuel.

Crystallization transforms the liquid form into a solid state, impeding pumping and transfer. External temperatures, along with the inherent crystallization properties, are beyond our control. It is crucial to exercise caution and awareness when procuring Sodium Hydroxide 50% during colder seasons. ### 1.1 Product identifier | Identification of the substance | Sodium Hydroxide | | ------------------------------- | --------------------- | | Registration number (REACH) | 01-2119457892-27-xxxx | | CAS number | 1310-73-2 | ## Our Operational Measures for Successful Transfer At Marine Care, Sodium Hydroxide 50% is stored in heated bulk tanks at 30 °C. In colder months (November through March in ARA), we exclusively fill IBCs on demand, mere minutes before dispatching them directly to vessels. Our trucks employ insulated trailers to slow down the cooling rate. For deliveries via third-party logistics companies (e.g., barges), coordinate with your vessel's agent to schedule barge loading upon the truck's arrival. The barge should promptly depart once loading is completed. Despite our preventive measures, crystallization risk is inherent in dealing with natural phenomena. This risk is acknowledged at the time of ordering.

Caretreat AWP AF has a high efficiency and can be used over a wider temperature and pH range than conventional antifoam. Caretreat AWP AF has been carefully formulated for optimal stability, especially at high temperatures, in order to avoid siloxane precipitation. The selected chain lengths and molecular weight ensures an optimum defoaming effect and prevents foam built-up. ## Advantage - Can be applied in as well hot as cold water - Defoams immediately - Remains active for a long time - Chemically inert product, resistant to chemical attack ## Applications / Directions for Use Caretreat AWP AF has to be used undiluted for maximum efficiency. Experimental trial is the best way to determine the optimal dosage of the product. Generally the optimal AWP AF dosage is between 10 and 100 ppm according to the application and to the stability of the foam. Caretreat AWP AF can be diluted in either hot or cold water to obtain a better dispensability in the foaming medium, but the efficiency of the AWP AF will be affected. In case of dilution we recommend not to exceed a dilution ratio of 1:10. The diluted product must be used immediately. ## Dosage See Applications / Direction for use. ## Properties | pH (1 % solution) | 7 - 8 | | ----------------- | -------------- | | Density | 0,98 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | White emulsion | ## Approvals N/A ## Safety _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-205 Caretreat AWP AF - rev. 0 111019](https://www.marine.care/documents/200/PDS-08-205_Caretreat_AWP_AF_-_rev._0_111019.pdf) --- --- title: Caretreat Oxygen Control DH url: "https://www.marine.care/products/caretreat-oxygen-control-dh/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Boiler water oxygen scavenger on DEHA basis for use in all types boiler systems categories: - Water Treatment --- # Caretreat Oxygen Control DH **Categories**: [Water Treatment](/product-categories/water-treatment/) - **Document number**: PDS-08-170 - **Revision**: 3.0 - **Revision date**: 2025-05-21 - **Language**: EN ## Description Caretreat Oxygen Control DH is a concentrated liquid organic amine based product. The product removes oxygen rapidly in the boiler water. Caretreat Oxygenen Control DH further prevents corrosion by oxygen and is an excellent passivator of steel surfaces. Caretreat Oxygen Control DH also neutralizes acids that tend to carry over to the condensate system. Caretreat Oxygen Control DH does not form carbon dioxides. Due to its volatility, Caretreat Oxygen Control DH acts as an oxygen scavenger throughout the entire boiler system due to steam carryover and reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system. Caretreat Oxygen Control DH is a safe to use and environmentally friendly product in comparison most of the equivalent oxygen scavengers. ## Advantage - Prevents corrosion in LP/MP boiler systems (condensate/feedwater/boiler) - Environmentally safe, non-toxic product - Simple and accurate testing - Effective under all operating conditions ## Applications Caretreat Oxygen Control DH can be used in any type low, medium and high pressure boiler system. Caretreat Oxygen Control DH can be used in the following systems: - evaporated - feedwater - boiler - deaerator ## Directions for Use _Standard water treatment:_ Caretreat Oxygen Control DH can be added directly to the feed water. We strongly recommend this is done by using a dosing pump. In high pressure boilers it is recommended to dose Caretreat Oxygen Control DH in the deaerator. It is also recommended to continually dose Caretreat Oxygen Control DH in conjunction with other Caretreat boiler water treatment products. ### Control limits The boiler water must meet the following conditions: - p-Alkalinity : 100-280 ppm CaCO~3~ - Chlorides : max. 300 ppm Cl^-^ (Low pressure boilers) : max. 100 ppm Cl^-^ (Medium pressure boilers) - pH : 9.5 to 10.8 - Conductivity : 400 to 2000 µS/cm (Low pressure boilers) : 400 to 1000 µS/cm (Medium pressure boilers) - Phosphate : 25-45 ppm PO~4~^3-^ - OXYGEN CONTROL DH : 0.1 - 0.3 ppm ### Initial dosage Caretreat Oxygen Control DH is initially dosed in the feedwater line, based on the amount of dissolved oxygen. Water with a temperature of 60-80 °C has a maximum of 5 ppm dissolved oxygen. To remove 5 ppm of dissolved oxygen 100 ml Caretreat Oxygen Control DH is added to the feedwater system, per tonnage of boiler volume. After dosing and circulation of the boiler water, the concentration of Caretreat Oxygen Control DH is analyzed and should be 0.3 ppm. When the concentration is lower than 0.1 ppm another 25 ml Caretreat Oxygen Control DH is dosed per ton boiler volume. ### Daily dosage The concentration of Caretreat Oxygen Control DH should be analyzed daily and the value should be kept at 0.1-0.3 ppm. Generally dosing of Caretreat Oxygen Control DH is 5-15 ml per day per ton boiler volume. ## Test Kit Caretreat Oxygen Control DH concentration can be analyzed with the Marine Care Oxygen Control test kit. ## Dosing Systems Marine Care supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application. ## Properties | Property | Value | | -------------- | -------------- | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals IMO Approved ## Health & Safety _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-170 Caretreat Oxygen Control DH - rev. 3 210525](https://www.marine.care/documents/181/PDS-08-170_Caretreat_Oxygen_Control_DH_-_rev._3_210525.pdf) --- --- title: Caretreat C.I.L. url: "https://www.marine.care/products/caretreat-cil/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Corrosion Inhibitor Liquid for fresh water storage and delivery systems associated with firefighting installations categories: - Water Treatment --- # Caretreat C.I.L. **Categories**: [Water Treatment](/product-categories/water-treatment/) - **Document number**: PDS-08-223 - **Revision**: 0.0 - **Revision date**: 2020-10-21 - **Language**: EN ## Description & Application Caretreat C.I.L. is a silica based product for corrosion reduction in (fresh) water storage and delivery systems associated with firefighting installations.

We advise testing of the Caretreat 2 Diesel level with the Marine Care Cooling water test kit. categories: - Water Treatment --- # Caretreat 2 Diesel **Categories**: [Water Treatment](/product-categories/water-treatment/) - **Document number**: PDS-08-180 - **Revision**: 6.0 - **Revision date**: 2024-08-19 - **Supersedes**: 5.0 - **Language**: EN ## Description Caretreat 2 Diesel is a liquid blend of nitrite, borate and polymer based corrosion inhibitors with a suitable buffer to ensure stable pH conditions. Caretreat 2 Diesel protects the diesel cooling water system as well as any auxiliary cooling water system from corrosion, sludge formation and scale. ## Advantage - Suitable for slow, medium and high speed engines - Effective corrosion inhibition on ferrous and non ferrous metals - Prevents scale and sludge built up - Approved by major diesel engine manufacturers ## Applications Caretreat 2 Diesel can be used in multi-metal: - Diesel cooling water systems, - Compressor cooling water systems, - General cooling water systems and central heating systems. ## Directions for Use Starting with the treatment of a system, the nitrite level must be kept at the higher nitrite level of the corresponding chloride concentration by testing and dosing daily. If the system is passivated the testing frequency and dosing can be reduced to once a week. Always add Caretreat 2 Diesel at a point where the circulation is high. Most modern systems header tanks are purely for expansion and have little or no circulation. Also they are often fitted with an internal baffle which can have the effect of trapping treatment and subsequent difficulty in obtaining the correct levels. The majority of loss in treatment levels will be due to leakage and subsequent dilution by make up water (distilled water should always be used). We advise testing of the Caretreat 2 Diesel level with the Marine Care Cooling water test kit. Recommendations for cooling water treated with Caretreat 2 Diesel: - Nitrite: 1500-3000 ppm NO~2~ - Chloride: max. 50 ppm Cl^–^ (HT systems) - Chloride: max. 100 ppm Cl^-^ (LT systems) - Hardness: max. 180 ppm as CaCO~3~ - pH: 9,0 - 10,0 ### Remarks On new buildings or overhauled systems, follow engine manufacturer's advice or consult Marine Care. If changing to Caretreat 2 Diesel from nitrite borate based products of another make, start dosing Caretreat 2 Diesel using Marine Care tests. Caretreat 2 Diesel will slowly remove sludge and other residues during the first month. This can result in slightly cloudy water which will clarify after draining small quantities of water and as make up water is added, leaving the system extremely clean. It is not necessary to drain existing cooling water completely unless inspection has shown excessive contamination. Marine Care can give advice on cleaning systems. ### Chloride In general the chloride concentration of the cooling water should be kept below 50 ppm in HT systems and below 100 ppm in LT systems. For every 10 ppm chloride above 50 ppm, increase the nitrite concentration with 100 ppm. In case chloride concentration in a system is too high refresh (partly) the system with low chloride and low hardness water (distilled water). Refer to the engine manufacturer for the recommendations regarding chloride, sulfate and hardness concentrations. ## Dosage Caretreat 2 Diesel is used in a dosage of 1500 - 2500 mg/l nitrite (NO~2~^-^), depending on the chloride level and system, please refer to the engine manufacturers instructions on recommended nitrite levels: | Chloride Concentration | Initial Dosage | Nitrite Level | | ---------------------- | ----------------------------- | --------------------- | | 0 - 50 ppm Cl- | 6 - 10 ltr/m^3^ cooling water | 1500 - 2500 ppm NO~2~ | | 50 - 100 ppm Cl- | 7-12 ltr/m^3^ cooling water | 1750 - 3000 ppm NO~2~ | ## Dosing Systems Caretreat 2 Diesel is normally dosed by a timer based dosing system consisting of a timer operated metering pump, dilution tank and injector. Marine Care supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application. ## Properties | Chloride Concentration | Initial Dosage | | ---------------------- | --------------------------- | | 0 - 50 ppm Cl- | 6 - 10 ltr/m3 cooling water | | 50 - 100 ppm Cl- | 7-12 ltr/m3 cooling water | | Physical state | Liquid | ## Approvals - Approved by Wärtsilä, MAN and MAK. - Marinfloc approved OWS compatible - Approved by Norwegian Institute of Public Health ## Safety _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-180 Caretreat 2 Diesel - rev. 6 190824](https://www.marine.care/documents/187/PDS-08-180_Caretreat_2_Diesel_-_rev._6_190824.pdf) --- --- title: Carecoat Recoseal 10 url: "https://www.marine.care/products/carecoat-recoseal-10/" type: products.ProductsPage published: 2026-05-22 updated: 2026-06-24 description: High solid 2-component clear-transparent polymeric coating for color restore, gloss recovery, UV resistance and long-term surface protection categories: - Cruise - General Maintenance & Engine Room --- # Carecoat Recoseal 10 **Categories**: [Cruise](/product-categories/cruise/) · [General Maintenance & Engine Room](/product-categories/general-maintenance-and-engine-room/) - **Document number**: PDS-08-201 - **Revision**: 1.3 - **Revision date**: 2023-05-10 - **Language**: EN ## Description Carecoat Recoseal 10 is a unique high solid, 2-component clear-transparent polymeric coating based on latest low molecular weight technologies for color restore, improved gloss, enhanced UV resistance and long-term protection of painted, coated, plastic, ceramic, fiber reinforced polymer, metal, wooden and stone surfaces that are weather-beaten discolored, chalked and/or eroded.

Caretreat Scrubber Mix is based on highly charged aluminum, enabling less of it to do more. This results in lower dosages and therefore reduces sludge volumes and pH adjustment demands. Coagulation is an intermediary step, but it is essential to the physicochemical treatment wastewater. This is the first step in the elimination of colloidal particles and its main function is to destabilize the particles. This destabilization is essentially the neutralization of the electrical charge present on the surface of the particle thus facilitating the agglomeration of the colloids. ## Advantage - Economical to use - effective at lower dosage levels - Achieve high particle removal efficiency - Easily soluble in water; dissolves rapidly - High efficiency - Easily soluble in water - High dewatering rate ## Applications Caretreat Scrubber Mix is taking care of agglomeration of the dispersed colloidal particles. These particles are assembled in larger aggregates called flocs or microflocs. Caretreat Scrubber Mix, creates lower turbidity and better particle separation. Caretreat Scrubber Mix is used in conjunction with our flocculant Caretreat Scrubber Pol, for optimal sludge dewatering. Caretreat Scrubber Mix is used before the Bleed off treatment system, as a hydro cyclone or other type of separator. ## Directions for Use Caretreat Scrubber Mix is dosed by a diaphragm metering pump.

In the evaporator, the seawater is heated to the required temperature and is then partially evaporated at atmospheric or low pressure. It then condenses and is collected as distillate. Since the seawater contains large quantities of salt in solution it is evident that the heating and evaporation will very rapidly lead to scaling of the heat transfer surfaces. The scale deposits build up and lower the plant efficiency by severely impairing the heat transfer. Resulting in considerably reduced output. Scaling is prevented by the use of Caretreat 1 Evaporator. ## Advantage - Prevents scale formation at temperatures up to 160 °C - Reduces foaming and maintains optimum plant performance - Reduces carry-over - Environmentally safe product ## Applications Caretreat 1 Evaporator can be used on any type of evaporator. ## Directions for Use Caretreat 1 Evaporator should be diluted in freshwater and fed continuously to the evaporator feed water line or directly to the evaporator shell using a recommended dosing system consisting of dosing tank with flowmeter and suitable eductor, or a metering pump system. ## Dosage Caretreat 1 Evaporator is continuously dosed at a rate of 30 ml/ton distilled water produced. ## Dosing Systems Caretreat 1 Evaporator is normally dosed by a gravity dosingsystem consisting of a dilution tank, flowmeter, meteringvalve and injector. _Marine Care_ supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application. ## Properties | Article number | 14401 | | -------------- | -------------- | | pH | 7 | | Density | 1,1 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals Approved by the Norwegian Institute of Public Health ## Safety _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-179 Caretreat 1 Evaporator - rev. 0 241018](https://www.marine.care/documents/188/PDS-08-179_Caretreat_1_Evaporator_-_rev._0_241018.pdf) --- --- title: Caretreat Activated Carbon 200 url: "https://www.marine.care/products/caretreat-activated-carbon-200/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-06 description: Coconut-shell activated carbon for purification of drinking water, swimming pools, and waste water treatment.

It protects the diesel engine cooling water system as well as any auxiliary cooling water systems from corrosion, sludge formation and scale. Caretreat CWT AL10 is suitable for cooling systems with maximum 10% aluminum alloys present. ## Advantage - Suitable for slow, medium and high speed engines - Effective corrosion inhibition on ferrous and non ferrous metals - Aluminum corrosion inhibition up to 10% aluminum alloys present - Prevents scale and sludge built up - Approved by major diesel engine manufacturers ## Applications Caretreat CWT AL10 can be used in multi-metal: - diesel cooling water systems, - compressor cooling water systems, - general cooling water systems and central heating systems. ## Directions for Use Starting with the treatment of a system, the nitrite level must be kept at the higher nitrite level of the corresponding chloride concentration by testing and dosing daily. If the system is passivated, the testing frequency and dosing can be reduced to once a week. Always add Caretreat CWT AL10 at a point where circulation is high. Most modern systems header tanks are purely for expansion and have little or no circulation, preferably this is not used as dosing point. The majority of loss in treatment levels will be due to leakage and subsequent dilution by make up water (distilled, RO or DI water should always be used). We advise testing of the Caretreat CWT AL10 level with the Marine Care Cooling water test kit. Recommendations for cooling water treated with Caretreat CWT AL10 : Nitrite: 1000-1500 ppm NO~2~^-^ Chloride: max. 100 ppm Cl^-^ Hardness: max. 100 ppm as CaCO~3~ pH: 8,7 - 9,5 _Remarks_ On new buildings or overhauled systems, follow engine manufacturer's advice or consult Marine Care. If changing to Caretreat CWT AL10 from nitrite borate based products of another make, start dosing Caretreat CWT AL10 using Marine Care tests. Caretreat CWT AL10 will slowly remove sludge and other residues during the first month. This can result in slightly cloudy water which will clarify after draining small quantities of water and as make up water is added, leaving the system clean. It is not necessary to drain existing cooling water completely unless inspection or analysis results of cooling water, has shown excessive contamination. Marine Care can give advice on cleaning contaminated systems. ## Dosage Caretreat CWT AL10 is used in a dosage of 20-30 liter per 1000 liter system volume and will give a 1000 - 1500 mg/l nitrite (NO~2~) concentration, depending on the chloride level and engine type, please refer to the engine manufacturers instructions on recommended nitrite levels: *Table 1: Adjust Nitrite Concentration — Chloride Concentration vs Initial Dosage* | Chloride Concentration | Initial Dosage | Nitrite Level | | ---------------------- | ------------------------------ | ------------------------ | | 0 - 50 ppm Cl^-^ | 20– 24 ltr/m^3^ cooling water | 1000 - 1200 ppm NO~2~^-^ | | 50 - 100 ppm Cl^-^ | 24 - 30 ltr/m^3^ cooling water | 1200 - 1500 ppm NO~2~^-^ | *Table 1: Adjust Nitrite Concentration — Dosing vs Nitrite Concentration* | Dosing / m^3^ | 1 Ltr | 5 Ltr | 10 Ltr | 15 Ltr | 20 Ltr | | --------------------- | ------ | --------- | --------- | --------- | -------- | | Nitrite concentration | 50 ppm | 250 ppm | 500 ppm | 750 ppm | 1000 ppm | | Adjust with CWT AL10 | | 19 L/m^3^ | 15 L/m^3^ | 10 L/m^3^ | 5 L/m^3^ | ## Dosing Systems Caretreat CWT AL10 is normally dosed by a timer based dosing system consisting of a timer operated metering pump, dilution tank and injector. _Marine Care_ supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application. ## Monitoring Cooling water should be monitored regularly on pH Value, nitrite and chloride concentrations with _Marine Care_ Cooling Water Test Kit. Log the analysis results in a log book or electronically in E-care. Results of the analysis are compared with the specifications and adjusted according the table 1. Periodically an extended analysis, on at least dissolved copper and iron on cooling water, is highly recommended.

The flocculation step can only operate on water/wastewater where the particles are already destabilized by Caretreat Scrubber Mix. Caretreat Scrubber Pol is used for dewatering of sludge from the bleed off water treatment system of the exhaust gas scrubber(s). The product is used as well for closed loop as open loop scrubber systems. A high percentage Dry Solids after the dewatering equipment, reduces the amount of sludge to be landed or the be dried. ## Directions for Use Caretreat Scrubber Pol has to be diluted to 0,5 - 1 % as stable stock solution. The stock solution has to be diluted 10 times to a working solution. Dilution has to be done by a slow running mixer or a recirculation pump. The flocculant has to be added to reversed osmosis water. Avoid centrifugal pumps for polymer transfer, high sheer pumps will crack the molecular chains. Caretreat Scrubber Pol is dosed at a rate of 10 - 20 grams undiluted product per kg Dry Solids (DS). Best is to use a multipoint distribution header, distribution ring or pipe flocculator. As an average a wet scrubber produces: Dry Solids 0,1 - 0,4 kg/MWh Bleed off water 0,1 - 0,3 m3/MWh Spilled polymer is very slippery and should be absorbed onto an inert material and collected prior to thoroughly flushing with hot water. Agitate the product well before use. ## Dosage See Direction for use. ## Properties | pH | 6 - 8 | | ----------------- | ---------------------- | | Density | 1,0 g/cm^3^ | | Flashpoint | > 93 ˚C | | Physical state | Liquid, grey to white | | Viscosity @ 25 ˚C | 0,5 % 400 cP/mPa.sec) | | Viscosity @ 25 ˚C | 1,0 % 900 cP/mPa.sec) | | Viscosity @ 25 ˚C | 0,5 % 2300 cP/mPa.sec) | ## Health & Safety _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-173 Caretreat Scrubber Pol - rev. 3 100120](https://www.marine.care/documents/186/PDS-08-173_Caretreat_Scrubber_Pol_-_rev._3_100120.pdf) --- --- title: Sewage Effluent Test Kit url: "https://www.marine.care/products/sewage-effluent-testkit/" type: products.ProductsPage published: 2026-05-22 updated: 2026-07-08 description: Test kit for free and total chlorine categories: - Water Treatment - Water Treatment Test Kit --- # Sewage Effluent Test Kit **Categories**: [Water Treatment](/product-categories/water-treatment/) · [Water Treatment Test Kit](/product-categories/water-treatment-test-kit/) ## Health & Safety Some reagents required for tests shown in this booklet are classed as hazardous and as such, a minimum protection of gloves (rubber or plastic) and safety goggles/spectacles or facemask **MUST BE WORN**. In addition please note and observe the Risk and Safety phrases on each reagent container and follow handling guidelines as instructed. **GENERAL NOTES** - Avoid contact with skin or eyes - In case of contact with skin or eyes rinse immediately with plenty of running tap water, and seek medical attention - Seek attention if irritation persists - In case of ingestion, wash the mouth out thoroughly with water, try to vomit and seek medical attention ## Drop Test Method The test should take between 10 and 30 drops of titrant to reach the end point. If number of drops is outside this range, adjust the sample volume used. i.e. < 10 drops used, increase sample volume or > 30 drops, reduce sample volume. Rinse titration vessels with the sample to be tested or de-ionised or distilled water. 1. Hold dropper bottles vertically upside down and not inclined at an angle. ![tmp2ubneode img-010 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-010-39c61cc9.png) 2. Allow drops to form slowly and fall off under their own weight. ![tmp2ubneode img-002 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-002-f438aec6.png) 3. Keep dropper nozzles clean by wiping with a soft cloth or tissue. Especially remove encrustation caused by reagents drying out on the bottle tip. ![tmp2ubneode img-003 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-003-12da260a.png) 4. Do not shake drops off. ![tmp2ubneode img-004 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-004-499548f2.png) 5. Ensure droppers are not statically charged. An indication of this is a rapid stream of very small drops with no proper control of drop formation. ![tmp2ubneode img-005 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-005-f9990ae2.png) 6. Apply gentle pressure to the bottle walls to encourage drop formation if necessary. ![tmp2ubneode img-006 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-006-f80c454d.png) 7. Re-place the dropper cap immediately after use to prevent cross contamination. ![tmp2ubneode img-007 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-007-97816db5.png) 8. Never adjust the dropper tip aperture by inserting anything that may enlarge the opening or damage the restrictor. If the dropper tip becomes damaged, replace. ![tmp2ubneode img-008 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-008-951e776d.png) 9. Use syringes provided to obtain accurate sample volumes. Do not rely on the graduations on the titration vessels, which are for rough guidance only. ![tmp2ubneode img-009 (p4)](https://media.marine.care/original_images/tmp2ubneode-img-009-167e6690.png) ## Free Chlorine (0 - 30 mg/l) Note: Test should be carried out immediately on fresh samples. If adding chlorine in an intermittent dose, wait 10 - 15 minutes after dosing before sampling and testing. This does not apply to systems using continuous dosing equipment. 1. Take sample according to expected range. ![tmp2ubneode img-013 (p5)](https://media.marine.care/original_images/tmp2ubneode-img-013-6c17f28c.png) 2.

The test enables the Permanganate Value (PV) to be determined and the effluent classified as to its acceptability for discharge. 1. Take three (3) sample jars and fill each to the 100 ml mark with sewage effluent. 2. Add two (2) Acidifying SE tablets to each jar, mount the cap and shake to the tablets disintegrate. 3. To the first, second and third jars, add respectively 1, 2 and 3 Permanganate Value tablets. Mount all three caps and shake until the tablets are dissolved. 4. Wait for 30 minutes, then note how many jars have remained pink. Read the results from the below stated table. *Permanganate Value grading* | PERMANGANATE VALUE | Permanganate Value | Grading | | ------------------ | ------------------ | -------------- | | All Three | 0 - 10 | Excellent | | Two | 10 - 20 | Satisfactory | | One | 20 - 30 | Dubious | | None | Over 30 | Unsatisfactory | - When testing crude sewage, add 10 ml sample to each jar and make up to 100 ml mark with de-ionized or distilled water. Proceed with the test as described above the multiply the Permanganate Value by 10. - When testing settled sewage, add 20 ml sample to each jar and make up to 100 ml mark with de-ionized or distilled water. Proceed with the test as described above the multiply the Permanganate Value by 10. ## BOD, COD and TOC It is possible to derive an indication of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) from the result of the Permanganate Value test. This is based on the relationship between these measures of organic pollution obtained experimentally for domestic sewage and effluents. To convert the Permanganate Value (PV) for doestic sewage and effluent to probable BOD,COD and TOC values multiply by the following factors: *BOD, COD and TOC conversion factors from Permanganate Value* | BOD, COD AND TOC | Sewage | Effluent | | ---------------- | ------- | -------- | | Probable BOD | PV x 5 | PV x 1,5 | | Probable COD | PV x 10 | PV x 7 | | Probable TOC | PV x 3 | PV x 2 | ## Turbidity and Suspended Solids The turbidity test is designed to give a measure of the suspended solids content of the final effluent. It is also useful in following the day to day variation in the quality of sewage and effluent. The Palintest Turbidity Test uses a specially calibrated plastic tube. This provides the simplest possible method of performing this important test. 1. Hold the tube vertically over a white surface and view downwards. 2. Gradually pour in effluent sample until the black cross is just no longer visible. 3. Read off the graduation corresponding to the height of the sample. This represents the turbidity of the effluent in Jackson Turbidity units (JTU). For sewage effluents the gradations may also be taken as being approximately equivalent to the Suspended Solids Content as mg/l or ppm. ![tmp2ubneode img-025 (p10)](https://media.marine.care/original_images/tmp2ubneode-img-025-e5719e4a.png) The Royal Commission Standards for effluents recommends that the suspended solids contents of sewage effluent should not exceed 30 mg/l **Note:** The tube should be rinsed after use. Any staining may be removed by the use of a household detergent. ## E-coli Hygicult® E/ß-GUR Hygicult E/ß-GUR slides are intended for presumptive detection of bacteria belonging to the family Enterobacteriaceae and for identification of species producing ß-glucuronidase enzyme. The slide is covered on one side with modified VRB Agar (Violet Red Bile Agar with addition of glucose) which allows bacteria belonging to Enterobacteriaceae to grow as red colonies. The glucose also allows some other species to grow as red colonies. The other side of the slide is covered with colourless ß-Gur Agar. Species producing ß-glucuronidase are able to grow on this side as brown colonies. The test can be performed on-site for monitoring different types of materials, both solid and liquid. As required, the slides can be used as convenient transport media for samples. **Note:** The limit values for microbial count in normal drinking water are too low to be detected by the Hygicult method. ### Sampling To avoid contamination, the growth medium should not come into contact with any other material than the one to be tested. On the other hand, it is important that the growth medium makes full contact with the material to be tested. After sampling screw the slide tightly back into the tube. Three sampling methods are available depending on the material to be tested. 1. **Contact inoculation (Fig. 1a, 1b)** Solid surfaces can be tested by pressing each side of the slide firmly against the surface for three or four seconds. The slide should be held still during pressing. ![tmp2ubneode img-027 (p11)](https://media.marine.care/original_images/tmp2ubneode-img-027-3717e3ba.png) ![tmp2ubneode img-026 (p11)](https://media.marine.care/original_images/tmp2ubneode-img-026-08ae9a9e.png) 2. **Dipping (Fig. 2)** Fluid samples are tested by dipping the slide in the liquid for three or four seconds. Blot the last drops on absorbent paper. ![tmp2ubneode img-028 (p11)](https://media.marine.care/original_images/tmp2ubneode-img-028-ae678dfe.png) 3. **Swabbing (Fig. 3)** Semisolid materials or objects that are difficult to reach can be tested by carefully rolling a sterile swab over an area delimited using e.g. a frame. If the object is dry, the swab should first be moistened with sterile water. The moistened swab can also be used for obtaining samples from powders (e.g. spices) or viscous fluids. After swabbing the sample area, roll the swab gently over the agar surfaces of the slide from left to right and from bottom to top. ![tmp2ubneode img-029 (p11)](https://media.marine.care/original_images/tmp2ubneode-img-029-7f2ccc07.png) 4. **Incubation (Fig. 4)** Incubate the slide tightly enclosed in its tube at 35…37°C for 24–48 hours. ![tmp2ubneode img-030 (p12)](https://media.marine.care/original_images/tmp2ubneode-img-030-16723be8.png) 5. **Interpretation of results (Fig. 5)** Remove the slide from its tube after incubation and determine the microbial count (number of colony forming units, CFU) and examine the colour reactions by comparing with the model chart. Bacteria belonging to Enterobacteriaceae grow on the modified VRB Agar as red colonies. The glucose also allows some other gram-negative bacteria, e.g. Pseudomonas species, to grow as red colonies. ß-glucuronidase-positive organisms grow on β-GUR agar as colonies in various shades of brown. As the colouration may be weak for some strains at high densities (10^6–7^ CFU/ml), any shade of brown is indicative of ß-glucuronidase-positive growth. ß-glucuronidase activity is found in ca. 90 % of strains of Escherichia coli. Some species of Salmonella, Edwardsiella, Shigella and Yersinia are also ß-glucuronidase producers. Gram-negative strains without ß-glucuronidase activity grow as colourless colonies on this agar. The growth of gram-positive organisms is inhibited on both media. The following levels can be considered as a rough basis for evaluating the degree of contamination: Clean: 0 CFU/side Contaminated: 1 - 10 CFU/side Very contaminated: > 10 CFU/side ![tmp2ubneode img-031 (p12)](https://media.marine.care/original_images/tmp2ubneode-img-031-7b97fa9e.png) ### Warnings and precautions Do not use product beyond the expiry date marked on the kit. Do not use the kit if you notice - discoloration or dehydration of the growth medium - detachment of the growth media from the plastic slide - evidence of bacterial or fungal growth Do not touch the growth because any colony growing on the slide may be pathogenic. ### Limitations of the method When used as a contact slide, Hygicult E/ß-GUR equals the contact plate method in sensitivity, whereas the dip and swab procedures have a detection limit of 1000 CFU/ml. The allowed total microbial concentration of normal drinking water is too low to be reliably detected using Hygicult E/ß-GUR. Results obtained with different inoculation systems should not be compared. Valid comparisons can only be made among results obtained using the same technique on the same type of material. ### Storage Store the kit at room temperature (approx. 20 °C) protected from draught, temperature fluctuations and light sources. Avoid storage near heat-generating appliances. Do not allow to freeze. The expiry date (year-month-date) is marked on the box and on the cap of each slide. ## Parts List *Parts list Sewage Effluent Test kit 11915* | Parts list Sewage Effluent Test kit 11915 | Parts list Sewage Effluent Test kit 11915 | 11915 | | ----------------------------------------- | ----------------------------------------- | -------------- | | Description | Amount | Article number | | **Permanganate Value test** | | | | Acidifying SE, 20 strips of 10 tablets | 3 | 11947 | | Permanganate Value, 300 tablets | 1 | 11948 | | Test jar, 100 ml | 3 | 11990 | | | | | | **Free Chlorine 0 - 30 mg/l** | 1 | | | Reagent FCL1 65ml | 1 | 11950 | | Reagent FCL2 65ml | 1 | 11951 | | Syringe 10 ml | 1 | 11980 | | Test bottle 50 ml | 1 | 11991 | | | | | | **Free Chlorine 0 - 1 mg/l** | | | | Reagent DPD1, 10x10 | 1 | 11940 | | Reagent DPD3, 10x10 | 1 | 11941 | | Tablet crusher | 1 | 11992 | | Test tube square 10ml, with lid | 2 | 11993 | | Comparator | 1 | 11994 | | Chlorine Disc 0 - 1 mg/l | 1 | 11995 | | **pH 4 - 10** | | | | Universal pH, 10 x 10 tablets | 1 | 11954 | | | | | | **E-Coli Hygicult E/ß-GUR 68267** | | | | Test slides 10 ea. | 1 | 11958 | | Labels 10 ea. | 1 | 11959 | | | | | | **Turbidity and Suspended Solids** | | | | Test Tube scale 5 - 25 | 1 | 11997 | | Test Tube scale 30 - 500 | 1 | 11998 | | | | | | Temperature probe 0 - 100 °C | 1 | 11999 | ## When in Doubt - Contact us for advise - E-mail us all test figures over a period of at least 3 months **Datasheet**: [Test Kit Instructions - Caretech Sewage Effluent](https://www.marine.care/documents/230/Test_Kit_Instructions_-_Caretech_Sewage_Effluent.pdf) --- --- title: Sodium Bisulfite - 20% (NaHSO3) url: "https://www.marine.care/products/sodium-bisulfite-20/" type: products.ProductsPage published: 2026-07-10 updated: 2026-07-13 description: Sodium Bisulphite (NaHSO3) is widely used for dechlorination, oxygen scavenging, water treatment, and chemical processing categories: - Ballast Water - Raw Materials --- # Sodium Bisulfite - 20% (NaHSO3) **Categories**: [Ballast Water](/product-categories/ballast-water/) · [Raw Materials](/product-categories/raw-materials/) - **Revision**: GHS 6.0 - **Revision date**: 2025-12-29 - **Supersedes**: GHS 5 (18.08.2017) - **Language**: EN ## Description Sodium Bisulfite 20% (NaHSO3) is used in boiler water treatment, ballast water systems, reverse osmosis systems, wastewater treatment, and industrial cleaning processes where chlorine removal is required. ### 1.1 Product identifier | Identification of the substance | **Sodium Bisulfite - 20%** | | ------------------------------- | -------------------------- | | Registration number (REACH) | 01-2119524563-42-xxxx | | CAS number | 7631-90-5 | ## Important Marine Care supplies sodium bisulphite products for industrial and maritime applications.

It is normally used in conjunction with Caretreat 3 Boiler as part of the water treatment program. It removes oxygen efficiently in open feed systems and gives effective corrosion inhibition of boiler/exhaust gas economizer system surfaces by converting Fe~2~0~3~ (rust) to an organic iron compound. It also protects copper based metals. The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system's pipe work. Acidic condensate is the result of carbonic acid (H~2~C0~3~) being formed as CO~2~ is released in the steam. The use of Caretreat 4 Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present. ## Advantage - Environmentally safe, non-toxic product. - Unique single product for corrosion control throughout the condensate system. - Simple and accurate testing. - Effective under all operating conditions. - Protects boiler surfaces by forming an iron tannate film. ## Applications Caretreat 4 Condensate can be used in any type low and medium pressure boiler system. Caretreat 4 Condensate can be used in the following make-up water types: evaporated water, reversed osmosis water or demineralized water. ## Directions for Use Caretreat 4 Condensate is dosed at a rate which maintains a pH of 9.0 to 10.0 in the condensate returns. Oxygen entrainment largely depends on Hotwell temperatures and if these are maintained at above 80 ˚C the condensate pH range of pH 9.0 to 9.5 is adequate. If Hotwell temperature control is irregular and averages less than 80 ˚C, tighter control is necessary and condensate returns should be kept in the range pH 9.5 to 10.0. It is not necessary to carry out oxygen or product residual tests. ### Initial dosage Caretreat 4 Condensate is initially dosed at 0,2 ltr/m^3^ boiler water. Systems showing signs of corrosion should be dosed at up to 0,7 ltr/m^3^ boiler water for the first few days in order to passivate all metal surfaces. ### Daily dosage rates After initial dose, the dosage depends on the quantity of steam production. A minimum of 15 ml/ton steam produced, should be dosed to maintain correct treatment levels in conjunction with regular top and bottom blown down and a correct condensate pH. ## Dosing Systems Caretreat 4 Condensate must be dosed continuously in conjunction with Caretreat 3 Boiler in a metering pump/tank unit, discharging directly into the feed system and/or the exhaust gas economizer circulating pump discharge. It must **NEVER** be slug dosed to a running system via a Hotwell or by-pass feeder. _Marine Care_ supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application. ## Properties | Article number | 14404 | | -------------- | -------------- | | pH | 10,5 | | Density | 1,01 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals - Caretreat 4 Condensate is according the FDA regulations for indirect food contact - Marinfloc Approved OWS Compatible _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-181 Caretreat 4 Condensate - rev. 2 190119](https://www.marine.care/documents/192/PDS-08-181_Caretreat_4_Condensate_-_rev._2_190119.pdf) --- --- title: Caretreat Chlorine Tablets url: "https://www.marine.care/products/caretreat-chlorine-tablets/" type: products.ProductsPage published: 2026-05-22 updated: 2026-05-22 description: Trichloroisocyanuric acid based sanitizer with 90% free chlorine for swimming pools, sewage, waste water and drinking water tanks. categories: - Water Treatment --- # Caretreat Chlorine Tablets *Sanitizer and free chlorine stabilizer for swimming pools, sewage and waste water, drinking water* **Categories**: [Water Treatment](/product-categories/water-treatment/) - **Document number**: PDS-08-184 - **Revision**: 1.0 - **Revision date**: 2018-10-24 - **Language**: EN ## Description Caretreat Chlorine Tablets are trichloroisocyanuric acid based.

Mud and Silt sediments are formed at places with insufficient flow velocity (below 1 m/s). Low flow velocity can occur in tanks, pipelines and cooling water circuits. CareFloc penetrates the mud and silt deposits and disperses the mud and silt particles into the treated water. ## Advantage - Non hazardous product - Prevents sludge from settling - Removes already settled sludge sediments - Low dosage rates - Eco-friendly - Biodegradable - Multipurpose - Dispersant - According FDA ## Applications / Directions for Use ### Cleaning dirty ballast tanks CareFloc must be dosed to the tank at a rate of 1 ltr. product to 10m^3^ water. If possible the water volume in the tank should be minimised to reduce product requirement. Maximum agitation should be provided by back flushing when pumped out. ### Ballast tank treatment To maintain good conditions in a clean tank CareFloc must be added at 1 ltr. product to 20 m^3^ water. Both dosage recommendations should be considered as the minimum for full effectiveness. CareFloc should be added via the tank covers, to avoid blending problems when dosed via vents or sounding tubes. If the latter is unavoidable, ensure that plenty of water is added directly after, to prompt blending. ### Open cooling water systems Fouled systems should be cleaned by injecting CareFloc at a rate of 1 ltr. product to 10 m^3^ circulating water flow over a 1 hour period every 24 hours. This rate can be reduced by 50 % once a system is reasonably clean and requires maintenance. ### Diesel engine cooling water systems Desludging must be carried out by injecting a minimum dose of 1 ltr. CareFloc to 10 m^3^ water contents. Small systems of less than 2.5 m^3^ should use 0.3 ltr. of CareFloc regardless of the exact contents. CareFloc should be injected into the system at a high dosing point; if the header tank is used for this purpose, ensure that the make-up valve is closed and water level lowered below the cylinder levels before CareFloc is added to the tank. Add the calculated volume of CareFloc to the empty tank and then open the make-up valve to refill the system. This ensures that the product enters the cooling circuit. Circulate for 30 – 60 minutes then completely drain the system as quickly as possible using all drains and removing covers if practical. Supply of untreated water whilst draining will assist in removing treated sludge. Repeat the operation if the sludge amount is excessive. ### Heat exchangers – sea water side _Static method_ Isolate the heat exchanger and add 1 ltr. CareFloc to 10 m^3^ water contents. If possible, agitate with a compressed air line or temporary circulation. After 30 - 60 minutes, flush thoroughly with water to remove all dispersed deposits. **Note**: If "on load" cleaning of specific coolers is required, inject upstream of the unit 1 ltr. CareFloc per 10 m^3^/h flow. ### General hints Long term contact of CareFloc with sludge, reduces its effectiveness. This should be considered in ballast tanks which are not continuously being discharged. Sludge should be removed within seven days maximum.

IMO MEPC compliant categories: - Hold cleaning - General Maintenance & Engine Room --- # Caretan Corrosion **Categories**: [Hold cleaning](/product-categories/hold-cleaning/) · [General Maintenance & Engine Room](/product-categories/general-maintenance-and-engine-room/) - **Document number**: PDS-08-92 - **Revision**: 2.0 - **Revision date**: 2022-02-18 - **Language**: EN ## Description Caretan Corrosion is an organic acid and chelating polymers based rust converter with excellent dispersing properties. Caretan Corrosion reacts quickly with rust and transforms iron oxides into a stable water insoluble blue-black metallo-organic complex. ## Advantage - Neutralizes the corrosion process - Quick reaction with rust - Creates a thorough chemical passivation making it a sound base for application of most paint or coating systems - Gives a water insoluble hydrophobic film - Is non-hazardous, non flammable and the film is fire retardant - Only minimum surface preparation required ## Application On all rusted steel surfaces before painting or repainting when preparation by sandblasting is a problem, e.g. cargo holds, decks, hatch covers, superstructures, pipelines, winches, rails etc. It is also used on sandblasted surfaces to prevent or passivate “flash rust”. Beyond being particularly suitable for use in the highly corrosive marine atmosphere it is also suitable for use on offshore rigs, in shipyards and refineries. ## Directions for Use Remove loose rust, rust scales/flakes by thorough wire brushing. Millscale, rust chips, blisters, deteriorated paints, oil, grease etc. should also be removed if present. In heavy industrial and marine atmospheres rust always contains soluble salts. It is important to remove atmospheric salts by water wash with freshwater prior to application of Caretan Corrosion. Caretan Corrosion is ready to use. 1 single thin application is sufficient. Apply brush, roller or spray. 1 liter covers approx. 20 m^2^. Reaction time is 3 hours. If the rust converter is applied in confined areas, reaction time may be somewhat longer. Caretan Corrosion may be applied to damp rusted surfaces. Caretan Corrosion is compatible with mostly used paint types and coating systems, alkyd systems, modified alkyds, chlorinated rubber, epoxies, polyurethanes, vinyls and the new water-based paint systems. Caretan Corrosion is not a paint. Treated surfaces must be protected by suitable paint/coatings, preferably within 48 hours after application of Caretan Corrosion. Equipment should be washed and flushed in fresh water. **CAUTION:** The rust converter should NOT be applied on hot surfaces above 40°C such as e.g. a deck area in sunny tropical climate. Such areas should be treated only when the area has cooled down during the evening and left for reaction overnight. ## Dosage | Brushing | undiluted | | -------- | --------- | | Spraying | undiluted | ## Properties | Article number | 14301 | | -------------- | -------------- | | pH | 2,0 | | Density | 1,0 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-92 Caretan Corrosion - rev. 2 180222](https://www.marine.care/documents/158/PDS-08-92_Caretan_Corrosion_-_rev._2_180222.pdf) --- --- title: Wall Wash Test Kit url: "https://www.marine.care/products/wall-wash-test-kit/" type: products.ProductsPage published: 2026-05-22 updated: 2026-08-18 description: Complete test kit for hydrocarbon, PTT, chloride, pH, acid wash colour and stainless steel passivation tests. categories: - Tank cleaning - Equipment --- # Wall Wash Test Kit **Categories**: [Tank cleaning](/product-categories/tank-cleaning/) · [Equipment](/product-categories/equipment/) - **Document number**: PDS-08-250 - **Revision**: 1.1 - **Revision date**: 2022-08-19 - **Language**: EN ## Kit Contents **The wall wash test kit contains the following items:** - Lab Grade Methanol – (2.5 ltr glass bottle) - Lab Grade D.I.

Caretreat Scrubber Pol 7000 is designed for high rate dewatering of sludge from the bleed off watertreatment of wet exhaust gas scrubbers. ## Advantage - Economical to use – significantly lower dosage levels - Fast settling rates - Achieve high solids removal efficiencies - Easily soluble in water; dissolves rapidly - Effective over a wide pH range; does not alter the system pH ## Applications Flocculation is the step where destabilised colloidal particles (or the particles formed during the coagulation step) are assembled into aggregates. The flocculation step can only operate on water/wastewater where the particles are already destabilised by Caretreat Scrubber Mix. Caretreat Scrubber Pol 7000 is used for dewatering of sludge from the bleed off water treatment system of the exhaust gas scrubber(s). The product is used as well for closed loop as open loop scrubber systems. A high percentage Dry Solids after the dewatering equipment, reduces the amount of sludge to be landed or the be dried. ## Directions for Use Caretreat Scrubber Pol 7000 has to be diluted to 0,5 - 1 % as stable stock solution. The stock solution has to be diluted 10 times to a working solution. Dilution has to be done by a slow running mixer or a recirculation pump. The flocculant has to be added to reversed osmosis water. Avoid centrifugal pumps for polymer transfer, high sheer pumps will crack the molecular chains. Caretreat Scrubber Pol 7000 is dosed at a rate of 10 - 20 grams undiluted product per kg Dry Solids (DS). Best is to use a multipoint distribution header, distribution ring or pipe flocculator. As an average a wet scrubber produces: Dry Solids 0,1 - 0,4 kg/MWh Bleed off water 0,1 - 0,3 m3/MWh Spilled polymer is very slippery and should be absorbed onto an inert material and collected prior to thoroughly flushing with hot water. Agitate the product well before use. ## Dosage See Direction for use. ## Properties | Property | Value | | ----------------- | --------------------- | | pH | 6 - 8 | | Density | 1,0 g/cm^3^ | | Flashpoint | > 93 ˚C | | Physical state | Liquid, grey to white | | Viscosity @ 25 ˚C | 0,5 % 400 cP/mPa.sec) | | Viscosity @ 25 ˚C | 1,0 % 900 cP/mPa.sec) | _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [tmpdeh8_2op](https://www.marine.care/documents/247/tmpdeh8_2op-6be60856.pdf) --- --- title: Caretech Discharge Kit 31/2 url: "https://www.marine.care/products/caretech-discharge-kit-312/" type: products.ProductsPage published: 2026-05-22 updated: 2026-06-12 description: 2 inch pump set for rapid discharge of rinse water from cargo holds with head heights above 30 metres.

The product is used for fast and environmentally safe removal of hydrocarbons, like heavy fuel, from water surfaces at sea or in port. ## Advantage - Fast acting dispersion of oils - Contains no petrochemical solvents - User friendly and non-flammable ## Applications ### At sea and in port Careclean OSD Enviro has to be sprayed onto the oil slick. When using the product, the sea surface should be agitated using breaker boards, boat propellers, bow wave etc., to help to disperse the oil. When dealing with small spills from vessels, use a hand spray pump or an eductor and fire hoses. This will mix the dispersant with seawater. Agitating the seawater will help to break the oil slick as well as applying the dispersant. This technique has also proven valuable when dealing with small spills in ports and harbors between ships side, wharfs and pilings, etc., or any area which has difficult access. ### On Beaches an Shore Careclean OSD Enviro can be used for beach and shore cleaning. Before using Carelcean OSD Enviro on beaches, the local environmental, social, economic and political consideration and legislation should be taken in account. Where application is justified, the most appropriate method of use will depend on the type of shore line, oil type and amount of spill. When a beach has oily liquid from a spill, it is advisable to remove as much as possible mechanically before using a dispersant. The amount of dispersant used is dependent on the type of oil. In cases of light to medium crude oils and light to medium fuel oils, Careclean OSD Enviro will be sufficient. Apply the dispersant over the oil working from the low watermark upwards, before a rising tide, or in areas where it is calm or where are small tidal movements. Use hoses to wash down the shore line to remove oil from rocks and beach. ## Directions for Use Careclean OSD Enviro oil spill dispersant should be used neat and can be applied by spraying from the surface vessels. Used neat it will disperse oil in a ratio of about 2 to 4 times its own volume. For large spills, a pump unit is used that supplies the product to boom mounted nozzles. For small spills a hand spray pump or educator is used. ## Technical Information The effectiveness of the oil dispersant will vary depending on the state of the oil, i.e., its pour point and viscosity at sea temperature, the time of weathering, evaporating of the lighter fractions of oil, the formation of oil-in-water emulsions. This all will quickly increase viscosity, pour point and hence increase resistance to dispersion. To be effective, it is essential to use Careclean OSD Enviro as early as possible in the cleanup operation. We recommended users of oil dispersants to read the IMO publication “IMO/UNEP Guidelines on Oil Spill Dispersants Application and Environmental Considerations”. This book gives more information on the application of dispersants. We would also like to emphasize that the use of dispersants in many countries is governed by local authorities or Coast Guard. Permission to use the product can be required. ## Dosage | Method | Rate | | ----------- | --------------------------- | | Spraying | Undiluted | | Consumption | 1 liter per 2 - 4 liter oil | ## Properties | Property | Value | | -------------- | ------------- | | Article number | 14104 / 16104 | | pH | 6,5 - 7 | | Density | 1,00 g/cm^3^ | | Flashpoint | None | | Physical state | Liquid | ## Approvals Marinfloc Approved OWS Compatible ## Health & Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-70 Careclean OSD Enviro - rev. 3 180222](https://www.marine.care/documents/135/PDS-08-70_Careclean_OSD_Enviro_-_rev._3_180222.pdf) --- --- title: Careclean Aquawash url: "https://www.marine.care/products/careclean-aquawash-general-maintenance/" type: products.ProductsPage published: 2026-05-22 updated: 2026-08-06 description: Completely water based biodegradable general purpose cleaner categories: - General Maintenance & Engine Room --- # Careclean Aquawash (General Maintenance & Engine Room) **Categories**: [General Maintenance & Engine Room](/product-categories/general-maintenance-and-engine-room/) - **Document number**: PDS-08-48 - **Revision**: 4.0 - **Revision date**: 2018-09-10 - **Language**: EN ## Description Careclean Aquawash is a liquid detergent containing anionic and non-ionic surfactants and complexing agents with good foaming qualities. Careclean Aquawash rapidly penetrates and removes oil, fat and grease. Careclean Aquawash is used as a multi-purpose cleaner in the engine room, on deck, in the accommodation and as tank cleaner. ## Advantage Careclean Aquawash has a neutral pH and can be used on most common metals, synthetic materials, rubber and hardened coatings. ## Features - Environmental-friendly - Biodegradable - Suitable on most materials - Pleasant odor - Non Flammable - Approved by: IMO, Marinfloc ## Applications **Spraying:** Careclean Aquawash is sprayed on, undiluted, and left for 20 - 60 minutes. It must then be hosed off with plenty of water, whilst brushing the surfaces. **General Cleaning:** Careclean Aquawash can be diluted to a 2 % solution in water for light contaminations. It must be allowed to soak for 1 - 15 minutes before rinsing with a waterjet. The effectiveness of the product is increased by using water at a temperature of 20 up to 60 ˚C for dilution and rinsing. **Tank Cleaning:** Before cleaning with Careclean Aquawash it is recommended to prewash with hot water. For drying or semi-drying oils a prewash with cold water should be carried out immediately after discharge of cargo to retard oxidation and hardening of oil residues. After one (1) cycle slowly start to increase the water temperature to increase effectiveness of the prewash. **Recirculation Method:** Recirculation is highly effective and widely used. In this method a chemical solution is pumped under pressure in a closed recirculation circuit via a mechanical tank washing machine. The chemical solution is normally prepared in the tank to be cleaned or the slop tank. Heat is achieved by a heat exchanger, steam coil or live steam injection. The advantages of this method are that the heat and chemicals are recovered and can be used again to clean additional tanks. Depending on the degree of contamination Careclean Aquawash is circulated as a 1 - 5 % solution for a minimum period of 1 hour. The water temperature should at least be 50 °C, but preferably as hot as possible to increase the cleaning effect. After circulation rinse thoroughly with (fresh)water. **Spray Method:** Spray the tank surfaces with undiluted Careclean Aquawash until the surfaces are thoroughly soaked and let the product act for at least 30 minutes. Then rinse all tank surfaces with hot water for 45 minutes or as long as needed to remove the cleaning detergent. ## Dosage | Application | Dosage | | ---------------- | ----------------- | | Spraying | undiluted | | General Cleaning | 2 % in freshwater | | Tank Cleaning | 1-5 % solution | ## Properties | Property | Value | | -------------- | ------------- | | Article number | 14110 / 16110 | | pH | 9 | | Density | 1,02 g/cm^3^ | | Flashpoint | None | | Physical state | Liquid | ## Approvals - IMO approved in accordance with MEPC 590 Guidelines - Marinfloc Approved OWS Compatible ## Health & Safety For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label. **Datasheet**: [PDS-08-48 Careclean Aquawash - rev. 4 100918](https://www.marine.care/documents/114/PDS-08-48_Careclean_Aquawash_-_rev._4_100918.pdf) --- --- title: Careclean Rust url: "https://www.marine.care/products/careclean-rust-hold-cleaning/" type: products.ProductsPage published: 2026-05-22 updated: 2026-08-06 description: Acidic cleaning product to remove hardness stains and residues after cleaning operations and rust stains on paintwork.

This advantage can be up to 50% compared to traditional cleanings. Due to the excellent cleaning properties, the product works on many vegoil cargoes, such as: - CPO - Palm Stearin - CPKO - PFAD ## Advantage - Accelerated removal of PFAD and other vegetable oil residues **Save up to up to 50% in cleaning time** - NO Prewash when cleaning via slop tank depending on set-up - Can be used with sea and fresh water - Removes hardness and rust stains - Safe on epoxy coatings and stainless steel - Hydrocarbon free cleaning ## Application Vegetable oils and Fatty acids tend to leave white stains when cleaned with the most commonly used cleaning solutions, especially the cargo deriving from palm oil and high melting point vegetable oil cargo can account for challenging cleanings. In most cases a two phase cleaning is performed or suggested with an alkaline cleaning and subsequent acid cleaning to remove the white stains. An alkaline cleaning is preferably performed using fresh water as high alkalinity and seawater will intensify the formation of stains. Hardness salts in combination with high alkalinity and Fatty Acids will precipitate as white stains. Careclean Xcellerate VO prevents formation of precipitations from hardness salt and removes the vegetable oils in one step, even using seawater. ## Tank Cleaning Instructions In case PFAD is present, it is strongly recommended to start with a 2% solution of Careclean Xcellerate VO. Heat the solution up to at least 60 °C and circulate for at least 2 full cleaning cycles. It is advised to rinse tanks and systems after the cleaning. Careclean Xcellerate VO is suitable to be used on epoxy coatings and stainless steel, it is not suitable to be used on zinc coated tanks. Generally consider the following for cleaning with Careclean Xcellerate VO: - The prewash, if performed, should always be done at a temperature of at least 15 °C higher than the melting point of the cargo. - The prewash, recirculation solution and hotwash can also be performed with seawater - Final rinse should be performed with fresh water to remove salt deposits A rule of thumb is to have for every 500m^3^ tank volume at least 1m^3^ of cleaning solution containing 2 - 3% Careclean Xcellerate VO. Careclean Xcellerate VO is a unique product developed by Marine Care. Please contact us prior to use, for a cleaning advise based on your vegoil residues or specific cargoes, cleaning protocol and systems. ### Hardness stains – Tank cleaning Cleaning with 2% Careclean Xcellerate VO at a temperature of 60-70 °C to the tank wash machine. ## Dosage | Application | Dosage | | --------------------------------------- | --------------------------- | | Tank cleaning– PFAD & vegetable oil | 2 - 3% solution or; | | In case of recirculation at least | 30L per 500m^3^ tank volume | | Hardness stains | 2 % solution | ## Properties | Property | Value | | -------------- | -------------- | | pH | 2,0 | | Density | 1,2 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals - IMO approved in accordance with MEPC 590 - Major coating manufacturers.

Mud and Silt sediments are formed at places with insufficient flow velocity (below 1 m/s). Low flow velocity can occur in tanks, pipelines and cooling water circuits. CareFloc penetrates the mud and silt deposits and disperses the mud and silt particles into the treated water. ## Advantage - Non hazardous product - Prevents sludge from settling - Removes already settled sludge sediments - Low dosage rates - Eco-friendly - Biodegradable - Multipurpose - Dispersant - According FDA ## Applications / Directions for Use ### Cleaning dirty ballast tanks CareFloc must be dosed to the tank at a rate of 1 ltr. product to 10m^3^ water. If possible the water volume in the tank should be minimised to reduce product requirement. Maximum agitation should be provided by back flushing when pumped out. CareFloc should be added via the tank covers, to avoid blending problems when dosed via vents or sounding tubes. If the latter is unavoidable, ensure that plenty of water is added directly after, to prompt blending. ### Ballast tank treatment To maintain good conditions in a clean tank CareFloc must be added at 1 ltr. product to 20 m^3^ water. Both dosage recommendations should be considered as the minimum for full effectiveness. ### Open cooling water systems Fouled systems should be cleaned by injecting CareFloc at a rate of 1 ltr. product to 10 m^3^ circulating water flow over a 1 hour period every 24 hours. This rate can be reduced by 50 % once a system is reasonably clean and requires maintenance. ### Diesel engine cooling water systems Desludging must be carried out by injecting a minimum dose of 1 ltr. CareFloc to 10 m^3^ water contents. Small systems of less than 2.5 m^3^ should use 0.3 ltr. of CareFloc regardless of the exact contents. CareFloc should be injected into the system at a high dosing point; if the header tank is used for this purpose, ensure that the make-up valve is closed and water level lowered below the cylinder levels before CareFloc is added to the tank. Add the calculated volume of CareFloc to the empty tank and then open the make-up valve to refill the system. This ensures that the product enters the cooling circuit. Circulate for 30 – 60 minutes then completely drain the system as quickly as possible using all drains and removing covers if practical. Supply of untreated water whilst draining will assist in removing treated sludge. Repeat the operation if the sludge amount is excessive. ### Heat exchangers – sea water side _Static method_ Isolate the heat exchanger and add 1 ltr. CareFloc to 10 m^3^ water contents. If possible, agitate with a compressed air line or temporary circulation. After 30 - 60 minutes, flush thoroughly with water to remove all dispersed deposits. **Note**: If "on load" cleaning of specific coolers is required, inject upstream of the unit 1 ltr. CareFloc per 10 m^3^/h flow. ### General hints Long term contact of CareFloc with sludge, reduces its effectiveness. This should be considered in ballast tanks which are not continuously being discharged. Sludge should be removed within seven days maximum. CareFloc will function over the full pH range, however, it is more effective in slight alkaline conditions. Do not use less than 1 ltr. of CareFloc in 20 m^3^ water. ## Dosage See Applications / Direction for use. ## Properties | pH | 6,5 - 8,5 | | -------------- | -------------- | | Density | 1,3 g/cm^3^ | | Flashpoint | Not applicable | | Physical state | Liquid | ## Approvals - CareFloc is according FDA for indirect food contact _For detailed information on safety and health, please refer to the Material Safety Data Sheet MSDS and/or product label._ **Datasheet**: [PDS-08-214 CareFloc - rev. 2 030719](https://www.marine.care/documents/265/PDS-08-214_CareFloc_-_rev_9dxWNDB._2_030719.pdf) --- --- title: Careclean Degreaser GP url: "https://www.marine.care/products/careclean-degreaser-gp-cruise/" type: products.ProductsPage published: 2026-05-25 updated: 2026-07-13 description: General purpose emulsifying degreaser based on mild hydrocarbons and surfactants for tank cleaning, engine parts, filters and cooling water systems. categories: - Cruise --- # Careclean Degreaser GP (Cruise) *Emulsifying cleaning product for the removal of medium to heavy mineral oils and fats by spraying and brushing* **Categories**: [Cruise](/product-categories/cruise/) - **Document number**: PDS-08-125 - **Revision**: 4.0 - **Revision date**: 2018-09-17 - **Language**: EN ## Description Careclean Degreaser GP is a General Purpose degreaser based on mild hydrocarbons and surfactants. Careclean Degreaser GP is used for tank cleaning, cleaning of engine parts, filters and oil contaminated cooling water systems. ## Advantage - Universal applicable emulsifying product - Suitable for the removal of most mineral oils and fats and preservation agents - Safe for use on metals, epoxy and zinc‑silicate coatings ## Applications / Directions for Use ### Tank Cleaning Before cleaning with Careclean Degreaser GP, it is recommended to prewash with hot water. For drying or semi-drying oils a prewash with cold water should be carried out immediately after discharge of cargo to retard oxidation and hardening of oil residues. After 1 cycle, slowly start to increase the water temperature to increase effectiveness of the prewash. ### Recirculation Method Recirculation is highly effective and widely used. In this method a chemical solution is pumped via a closed loop through a mechanical tank washing machine. The chemical solution is normally prepared in the tank to be cleaned or in the slop tank. Heat is achieved by the use of a heat exchanger, steam coils or live steam injection. The advantages of this method are recovery and re-use of the heat and chemicals to clean additional tanks. Depending on the degree of contamination Careclean Degreaser GP is circulated as a 2 - 5 % solution for a period of 2 - 4 hours at 50 - 80 ˚C. After circulation rinse thoroughly with (fresh) water. One solution is commonly used to wash 2 - 3 tanks. ### Direct Injection Method Inject 2 - 5 % of Careclean Degreaser GP directly into the tank washing system. The recommended cleaning temperature is 20 - 60 °C. When completed rinse thoroughly with water. ### Spray Method (tank cleaning) Spray the tank surfaces with a 2 - 5 % solution of Careclean Degreaser GP and let the product act for 1 - 15 min. before spraying with a high pressure water jet. The efficiency of this product can be increased by using water of 50 - 80 °C. For very heavy contaminations a 25 % solution should be used. Leave the product to act for 10 to 60 minutes before spraying with a high pressure water jet. ### Cooling systems Along with the usual lime deposits, traces of mineral oils are often found in cooling systems. These oil and fat deposits hinder optimum removal of the hardness deposits by means of acid cleaners (e.g. Careclean F Descalex P). Therefore it is recommended to use an emulsifying cleaner before the acid cleaning, Careclean Degreaser GP is ideal in these cases. ### Cleaning of cooling systems / circulation method Fill the cooling system with a solution of Careclean Degreaser GP and water. Depending on the degree of contamination, use a 5 - 10 % solution of Careclean Degreaser GP in fresh water. Allow this emulsion to circulate for 12 ‑ 24 hours at a maximum temperature of 60 °C. After this operation, drain the cleaning liquid and rinse the system intensively with water until the outlet water remains clear. Add cooling water treatment Caretreat 2 Diesel into the system, diluted with demineralized or evaporator water. ### Spray method (general) Spray the contaminated objects until they are thoroughly dampened with undiluted Careclean Degreaser GP. Let the product act for 20 ‑ 60 minutes, then rinse the objects thoroughly with water. - Note: objects subject to corrosion should not be rinsed with water; in this case Careclean ECS Quick Dry can be used. ## Dosage | Method | Application | Dosage | | ----------- | ---------------- | ----------------------------------- | | Circulation | (tank cleaning) | 2 - 5 % in freshwater | | Circulation | (cooling system) | 5 - 10 % in freshwater | | Spraying | (tank cleaning) | 2 - 5 % in freshwater | | Spraying | (general) | 5 - 10 % in freshwater to undiluted | ## Properties | Article number | 14102 / 16102 | | -------------- | -------------- | | pH | Not applicable | | Density | 0,85 g/cm^3^ | | Flashpoint | > 62 ˚C | | Physical state | Liquid | ## Approvals - IMO approved in accordance with MEPC 590 - Marinfloc Approved OWS Compatible - Major coating manufacturers.

Stainless steel is protected from corrosion by a thin layer that consists mainly of chromium oxide. Oxygen from the atmosphere is normally able to form and maintain this passive layer. Contamination, surface defects and imperfections disturb the formation and repair of the chromium oxide layer and reduce the resistance to severe or local corrosion. Therefore it is very important to test if your stainless steel is still passive to prevent corrosion and damage. The measure of passivation of stainless steel can be determined with palladium chloride reagent. The reagent keeps colour on good passivated stainless steel. A black spot will appear when the surface has not been passivated correctly. Various qualities of passivation will give grades of grey shades, ranging from light (acceptable) to dark unacceptable). ## Kit Contents The Passivation Test Kit contains: - Palladium Chloride Reagent (30ml drop bottle) - Demi water Squeeze Bottle (500 ml) - Latex Gloves (1 box) - Non woven cleaning pads (5 pcs) - Instruction Card ![tmpmv1cx2v2 img-003 (p1)](https://media.marine.care/original_images/tmpmv1cx2v2-img-003-8186cfe9.png) *Transport crate view showing kit contents* ![tmpmv1cx2v2 img-004 (p1)](https://media.marine.care/original_images/tmpmv1cx2v2-img-004-f81d6d33.png) *Crate includes palladium chloride reagent bottle, demi water squeeze bottle, gloves and cleaning pads* ## Test Procedure 1. Apply a drop of Palladium Chloride Reagent to the stainless steel surface. 2. Allow 3 minutes to react. If surface is not passive, edges of drop will start to discolor. 3. Rinse the surface with demi-water. After 3 minutes contact time and rinse, a not passive surface will turn gray to black. **Datasheet**: [PDS-08-252 - PassivationTestKit - rev. 0 010422](https://www.marine.care/documents/275/PDS-08-252_-_PassivationTestKit_-_rev._0_010422.pdf) --- --- title: Caretech Spectroscan UV-VIS SmartLog url: "https://www.marine.care/products/caretech-spectroscan-uv-vis-smartlog/" type: products.ProductsPage published: 2026-06-08 updated: 2026-06-12 description: Portable UV-vis spectrophotometer with touch screen and pre-programmed methods for wall wash testing and wash water analysis. categories: - Tank cleaning - Equipment --- # Caretech Spectroscan UV-VIS SmartLog **Categories**: [Tank cleaning](/product-categories/tank-cleaning/) · [Equipment](/product-categories/equipment/) - **Document number**: PDS-08-255 - **Revision**: 0.0 - **Revision date**: 2019-06-06 - **Language**: EN ## Description The new Caretech Spectroscan UV-Vis SmartLog is the leading analysis unit for wall wash testing and wash water analysis in the maritime market.

The presence of iron particles in stainless steel surfaces disturbs the chromium oxide layer, reducing the corrosion resistance locally. When embedded iron particles are not removed, serious (pit) corrosion is most likely to set in. ## Principle of Measurement The test is based on a reaction of potassium ferricyanide with iron in a strongly acid medium. The excess iron dissolves in this strongly acid medium as ferrous ion to form a blue complex, known as Prussian Blue. When during this test this blue discoloration becomes visible, it means that the surface of the stainless steel does not yet have the correct structure and has been insufficiently pickled. ## Kit Contents The Ferroxyl Test Kit contains: - 1 transparent 25 ml dropping bottle - 1 measuring scoop - 1 pack Ø 11 cm filter paper - pack latex gloves - 1 pack shoe covers - 1 mixing bottle - 1 demineralizer bottle (incl. resin) Reagents: - Ferroxyl reagent I - Ferroxyl reagent II ![tmp4ot5wspo img-003 (p1)](https://media.marine.care/original_images/tmp4ot5wspo-img-003-6f37ab74.png) ![Ferroxyl TestKit contents](https://media.marine.care/original_images/PDS-08-249_-_Ferroxyl_TestKit_-__rev._0.jpeg) ## Instructions for Use 1. Ensure you wear the proper PPE’s (gloves, glasses) and create a proper working area where the components of the test kit can safely be stalled. 2. Place 5 measuring scoops Ferroxyl reagent I in the dropping bottle. Add 25ml Ferroxyl reagent II to the scale mark. Close and shake bottle until the reagent I is dissolved. 3. Moisten a filter paper with 5 drops of the solution and place the moist filter paper on the surface to be tested. Wait for 60 seconds. 4. When blue discoloration of the filter paper starts to appear, the tested surface contains embedded iron and the pickling has not been done correctly (or the surface was afterwards contaminated again). 5. When no discoloration appears, remove the filter paper and rinse the surface with demineralized water (tap water can be mixed with the demineralizer resin to create demineralized water). _Note: the reagent solution can only be used for 2 hours for reliable results. After this time, a new solution needs to be made._ 1. Test surface should be dust free, if needed, wipe with moist cloth before applying the Ferroxyl test paper. 2. Make sure the test paper wetted with the Ferroxyl reagent is in full contact with the tested surface, avoid air bubbles by wiping them away. 3. After 60 seconds the first blue spots will appear if embedded iron particles are present. 4. Remove the test paper from the surface. 5. In case of larger particles, the blue discoloration will also be visible on the tested surface. It can be removed by pickling and/or passivation liquid. **Datasheet**: [PDS-08-249 - Ferroxyl TestKit - rev. 0](https://www.marine.care/documents/274/PDS-08-249_-_Ferroxyl_TestKit_-__rev._0.pdf) --- --- title: Oxilyser 3 url: "https://www.marine.care/products/oxilyser-3/" type: products.ProductsPage published: 2026-06-08 updated: 2026-07-13 description: Easy and accurate passivity measurement of austenitic and duplex stainless steel surfaces categories: - Tank cleaning - Equipment --- # Oxilyser 3 **Categories**: [Tank cleaning](/product-categories/tank-cleaning/) · [Equipment](/product-categories/equipment/) - **Language**: EN ## Description The corrosion resistance of stainless steels depends on the quality of a very thin oxide layer, the so called 'passive layer'. Maintaining this passive layer is one of the most important aspects in maintaining the quality of stainless steel. Damage of the passive layer, in time, will cause severe corrosion. Therefore, preserving the passive layer is a must. With the Oxilyser 3 you measure passivity fast and accurately. Besides a 0-100 passivity scale, a LED (green/red) will indicate passivity or not. The Oxilyser 3 helps you to avoid corrosion problems. ## Principle The principle of the Oxilyser 3 is based upon measuring the rest potential of the stainless steel surface combined with a sophisticated algorithm for evaluation. The electrolyte is a non toxic organic acid and filter paper strips function as electrolyte bearer. This method is the most direct way for measuring passivity. The scale of the LCD display is divided into 100 units. Passivity of three stainless steel groups can be measured: 1. 0% Molybdenum (AISI 304, 321, 304L, Wst. Nr. 1.4301, 1.4541, etc.). 2. 2% Molybdenum (AISI 316, 316L, 316Ti, Wst. Nr. 1.4404, 1.4571, etc.). 3. Duplex stainless and 6% Mo steel such as Wst. Nr. 1.4462, duplex 2205, duplex 2507, 254 SMO and 1943 hMo. ## Applications - Checking effectivity of pickling and passivating treatment - Checking passivity after unloading tanks with aggressive fluids like acids - Checking passivity after cleaning/rinsing, e.g. stainless steel storage tanks, transport tanks (shipping, industry, trucks, etc) ## Advantage The Oxilyser replaces the palladium chloride test as it is a more reliable and quick standard for passivity testing. Direct measurement, built in algorithm for passivity testing. The unit operates on a standard industrial quality 9V battery. ## Specifications - Objective result on LCD display. Scale 0 (active) to 100 (fully passive) - Passive or not LED passivity indication for three stainless steel groups - Measuring procedure fits into quality control and assurance procedures and corrosion monitoring systems. ## Oxyliser Kit Content - Oxilyser 3 base unit with 9V battery - Shockproof Epoxy Double Bridge Ag/AgCl2 reference electrode.

For drying or semi-drying oils a prewash with cold water should be carried out immediately after discharge of cargo to retard oxidation and hardening of oil residues. After 1 cycle slowly start to increase water temperature to increase effectiveness of the prewash. ### Recirculation Method Recirculation is highly effective and widely used. In this method a chemical solution is pumped via a closed loop through a mechanical tank washing machine. The chemical solution is normally prepared in the tank to be cleaned or in the slop tank. Heat is achieved by the use of a heat exchanger, steam coils or live steam injection. The advantage of this method is that heat and chemicals are recovered. Depending on the degree and nature of contamination, Careclean Multiclean is circulated as a 2 - 5 % solution for a minimum period of 2 - 6 hours at a temperature of 60 - 80 °C (depending on the type of cargo). After circulation rinse thoroughly with (fresh) water. In case the next cargo is high purity standard make sure to rinse with Demineralized (D.I.) water. ### Direct Injection Inject 2 - 5 % of Careclean Multiclean into the washing system. Maintain cleaning temperatures between 60 - 80 °C (depending on the type of cargo).

The system consists of a powerful pneumatic diaphragm pump mounted on a robust stainless steel frame equipped with an integrated magnetic fixation system. This magnetic locking mechanism keeps the pump securely in position on steel ship decks and tank tops, even during intensive operation and under the pulsations typically generated by pneumatic diaphragm pumps. The pump is especially suitable after cement and/or clinker cargoes, after which a strong acidic cleaning is done. The acid is the slops created by cleaning, is heavier than water and will concentrate in the bilges. When a traditional electric sump pump is used to pump the slops out, the steel or, in best case, brass impellor will slowly dissolve due to the low pH and cement/clinker particles. The Discharge Kit XXL can process high and low pH slops without any issue due to the full chemical resistant design and ability to handle even particles of 5 mm in size without wear issues. The pump is also ideal for transfer of Urea liquid from IBC/Tote to the vessel's manifold. The existing suction hose can be used to pump from top of IBC, or in case a 3" to 2" Camlock connector is used, the suction hose can be connected to the 2" male camlock connection, present at most IBC's/Tote's. The Caretech Discharge Kit XXL combines: - High pumping capacity - Reliable pneumatic operation - Easy installation - Robust marine-grade construction - Safe and stable onboard operation ## Technical Specifications | Specifications | Value | | ------------------------------ | ---------------------------------- | | Model | Caretech Discharge XXL | | Maximum lifting capacity | 40 – 55 meters | | Maximum capacity (free flow) | 568 ltr/min | | Maximum working pressure | 8.4 bar (0.84 MPa) | | Suction hose | 3" x 5 meters | | Discharge hose | 2-1/2" x 50 meters (2 x 25 meters) | | Air hose | 3/4" x 25 meters | | Pump dimensions (L x W x H) | 955 x 500 x 390 mm | | Package dimensions (L x W x H) | 1200 x 1000 x 1255 mm | ## Caretech Discharge Kit XXL Contents - Pneumatic diaphragm pump - Integrated magnetic fixation system - 5 meter suction hose with camlock connections - 2 x 25 meter discharge hoses with camlock connections - 25 meter compressed air hose - Stainless steel suction strainer - Pre-installed camlock couplings ![XXL kit-HR](https://media.marine.care/original_images/XXL_kit-HR_j0gdf2s.jpg) *Caretech Discharge Kit XXL complete kit: pneumatic diaphragm pump with stainless steel suction strainer (left) and coiled suction and discharge hoses with camlock connections (right).* **Datasheet**: [PDS-08-265](https://www.marine.care/documents/289/PDS-08-265_l8riXT1.pdf) --- --- title: Nitric Acid (HNO3) url: "https://www.marine.care/products/nitric-acid-hno3/" type: products.ProductsPage published: 2026-07-10 updated: 2026-07-15 description: Nitric Acid (HNO₃) is a strong mineral acid widely used in industrial cleaning, metal treatment, and chemical processing categories: - Tank cleaning - Ballast Water - Raw Materials --- # Nitric Acid (HNO3) **Categories**: [Tank cleaning](/product-categories/tank-cleaning/) · [Ballast Water](/product-categories/ballast-water/) · [Raw Materials](/product-categories/raw-materials/) ## Description Nitric Acid (HNO₃) is a strong mineral acid.

We supply the chemicals used at each stage of that process - from treating the water on the way in, to neutralising it before it goes back into the sea - all compliant with IMO requirements. **Pre-treatment:** Sodium hypochlorite (12–15%) is used to disinfect the ballast water when it's taken on board. **Neutralisation:** Before treated water is discharged, any remaining disinfectant has to be neutralised so it doesn't harm the marine environment. We supply several neutralising agents for this: sodium thiosulphate (powder or solution, 30% and 50%), sodium bisulphite solution (40%), and sodium metabisulphite powder. Which one you use depends on your system and dosing setup, our team can advise on this. **Tank cleaning:** Our CareFloc dispersant is used to break down and remove mud and silt buildup in ballast tanks and pipelines. ![damon-janis-hpBESFIlmyo-unsplash](https://media.marine.care/original_images/ries-bosch-ZZw8xM0s3sc-unsplash.jpg) ## Practical support, reliably available All products come with full technical documentation, and we're available to help you choose the right product and dosage for your specific system.

At Marine Care, we are one of the first and most experienced suppliers of caustic soda (sodium hydroxide) and urea 40% to the maritime industry, with over a decade of bunkering experience across ports worldwide. We supply via tank truck - and where truck access is restricted, such as in the Suez Canal - via IBC with full pumping service. Our product range covers all key reagents for wet exhaust gas scrubbers and SCR systems, including sodium hydroxide 50%, urea 40% (NOxCare™), and magnesium oxide, ensuring you have what you need, wherever you are. ![Tier 3 beskjært](https://media.marine.care/original_images/Tier_3_beskjaert.png) ## Setting new standards for Urea bunkering We have pioneered a fundamentally more efficient way to bunker urea. Our TIER III barge in Houston was the first of its kind in the world, a custom-built urea bunkering barge that eliminates IBC handling entirely and reduces bunkering time by up to 80%. Building on that success, we launched UREA-Xpress in Rotterdam, an exclusive partnership with Yara operating a 600 m³ barge loaded directly from Yara's Sluiskil terminal. Replacing up to 25 tank trucks or 600 IBCs per loading, UREA-Xpress dramatically reduces CO₂ emissions, plastic waste and port congestion while cutting cost and turnaround time for operators. It is not just a smarter way to bunker; it is the future of sustainable emission control supply. ![GTM-MC-HR-5](https://media.marine.care/original_images/GTM-MC-HR-5.jpg) ## Nox & Sox scrubber chemicals We are experts at bunker supplies of caustic soda and have supported vessels globally for over a decade.
