CB27 / AT-2972 is a high performance, traditional liquid sulfite catalyzed treatment product scientifically formulated for use as an oxygen scavenger in the treatment of boiler water systems.
CB27 / AT-2972 is a non-volatile, inorganic oxygen scavenger, which can be used in systems operating at pressures up to 65 barg. It begins to break down at pressures of 43 barg and is completely decomposed at pressures above 65 barg.
CB27 / AT-2972 prevents corrosion in boiler and other water systems by reacting with any dissolved oxygen in the water. Because of the catalyst contained in this product the rate of reaction with oxygen is greatly increased so that the oxygen is removed before it can begin to corrode metal surfaces.
CB27 / AT-2972 may also be used for the removal of chlorine.
- Excellent, non-volatile, inorganic oxygen scavenger.
- Rapid removal of oxygen leading to improved corrosion protection.
- Can be used in systems up to 65 barg.

Application & Dosage Information
CB27 / AT-2972 must be fed neat.
CB27 / AT-2972 must be fed continuously to the storage section of the deaerator below the water line via a stainless steel quill.
Product cannot be fed prior to the attemperation water take-off point
Product cannot be mixed with other chemicals either neat or in diluted form.
Product is compatible with most of our other internal boiler treatment programmes.
Dosages are based on 17.5 ppm of CB27 / AT-2972 per ppm oxygen, plus a residual of product in the feedwater based on ASME guidelines (3.3 ppm of product is required per ppm of sulphite residual).
It is always advisable to carry out a ‘Control Of Substances Hazardous to Health’ (COSHH) assessment before use.
