Caretreat Oxygen Control CH

Caretreat Oxygen Control CH is a concentrated liquid organic amine based product. The product removes oxygen rapidly in the boiler water. Caretreat Oxygen Control CH further prevents corrosion by oxygen and is an excellent passivator of steel surfaces. Caretreat Oxygen Control CH also neutralizes acids that tend to carry over to the condensate system. Caretreat Oxygen Control CH is a safe to use and environmentally friendly product in comparison most of the equivalent oxygen scavengers.

• prevents corrosion in all boiler systems (condensate/feedwater/boiler)
• environmentally safe, non-toxic product
• simple and accurate testing
• effective under all operating conditions

Caretreat Oxygen Control CH can be used in any type low, medium and high pressure boiler system. Caretreat Oxygen Control CH can be used in the following systems:

• evaporator
• feedwater
• boiler
• deaerator

Caretreat Oxygen Control CH 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 CH in the deaerator. It is also recommended to continually dose Caretreat Oxygen Control CH in conjunction with other Caretreat boiler water treatment products.

The boiler water must meet the following conditions:

• p-Alkalinity : 100-280 ppm CaCO₃
• 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 PO₄^3-
• Hydrazide : 0.8 - 1.5 ppm

Caretreat Oxygen Control CH is initially dosed in the feedwater line, based on the amount of dissolved oxygen. Water with a temperature of 60-80 ^oC has a maximum of 5 ppm dissolved oxygen. To remove 5 ppm of dissolved oxygen 125 ml Caretreat Oxygen Control CH 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 CH is analyzed and should be > 1 ppm. When the concentration is lower than 1 ppm another 25 ml Caretreat Oxygen Control CH is dosed per ton boiler volume.

The concentration of Caretreat Oxygen Control CH should be analyzed daily and the value should be kept at 0.8-1.5 ppm. Generally dosing of Caretreat Oxygen Control CH is 5-15 ml per day per ton boiler volume.

Caretreat Oxygen Control CH concentration can be analyzed with the Marine Care Oxygen Control Testkit.

Marine Care supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application.
