Accepta 2316 is a highly active cleaning agent and descaler based on sulphamic acid. Accepta 2316 is also supplied with a special film forming inhibitor to protect mild steel, stainless steel, copper and brass against acid attack. Accepta 2316’s inhibitor properties also serve as a penetrant and dispersant to enhance the effectiveness of the acid.
Accepta 2316 can be used to dissolve lime-scale (calcium carbonate) deposits in boilers,
calorifiers and heat exchangers.
NOTE - Accepta 2316 should NOT be used on aluminium or galvanised surfaces.
Dose rate for Accepta 2316 - This generally depends on the degree of scaling. Normally a 10% solution (100g per litre) will remove carbonate deposits. Up to 30% solutions may be used at temperatures below 70oC for removal of stubborn deposits. The inhibitor solution should be added at rate of 250ml per 25Kg of powder.
Completion of descaling should be determined by either testing acidity or pH periodically. When descaling is complete acidity or pH should be constant. If solution shows no acidity or pH rises to 4 or higher then more Accepta 2316 solution should be added.
After completion of descaling, equipment should be drained and flushed thoroughly with water and any acid effluent neutralised with Accepta’s neutraliser.
