Nickel Catalysed Sodium Bisulphite Oxygen Scavenger for Steam Boilers – 2973

This product is no longer available

It has been replaced by Accepta 2972

Description

Accepta 2973 is a high performance; liquid boiler treatment scientifically formulated using nickel catalysed sodium bisulphite and developed as an oxygen scavenger for the treatment of steam boilers and boiler water systems.

Accepta 2973 is a non-volatile, inorganic oxygen scavenger, which can be used in systems operating at pressures up to 65 barg. It contains 23% sodium bisulphite.

Accepta 2973 begins to break down at pressures of 43 barg and is completely decomposed at pressures above 65 barg.

Accepta 2973 prevents corrosion in boiler and other water systems by reacting with any dissolved oxygen in the water.

Because of the nickel catalyst contained in this boiler treatment product the rate of reaction with oxygen is greatly increased, so that the oxygen is removed before it can begin to corrode metal surfaces.

Accepta 2973 may also be used for the removal of chlorine.

Product Benefits

  • Formulated using nickel catalysed sodium bisulphite
  • Excellent, non-volatile, inorganic boiler water oxygen scavenger
  • Rapid removal of oxygen leading to improved corrosion protection
