Application & Dosage Information


To ensure rapid film formation and corrosion control the system should be pre-treated with Accepta 2312 for two or three weeks at twice the normal continuous dosage.

Continuous dosage

Accepta 2202 should be dosed to maintain a minimum of 100ppm in recirculation. For maximum control and economy it should be dosed continuously, excellent results being achieved employing an automatic proportional dosing unit POA.
