Description
Accepta 2561 is a high performance, low toxicity volatile oxygen scavenger scientifically formulated for the treatment of steam boiler systems, steam raising plant and hot water systems. Accepta 2561 contains DEHA.
Accepta 2561 removes dissolved oxygen from the feed water, boiler water and condensate lines and can be used in medium pressure hot water (MPHW) systems and steam raising plant.
Accepta 2561 works to protect all the bolier system from oxygen pitting corrosion. It passivates iron and copper surfaces through the formation of protective oxide layers.
Accepta 2561 does not contribute to boiler TDS.
Accepta 2561 contains DEHA.
