Corrosion Inhibitor & Scale Dispersant for Cooling Water Systems

Corrosion Inhibitor & Scale Dispersant for Cooling Water Systems

Accepta 2303 is a high performance, non-volatile cooling water corrosion inhibitor and scale dispersant scientifically formulated for the treatment and protection of open circuit evaporative cooling water systems and air conditioning plant facilities.

Accepta 2303 is a highly versatile cooling water product comprising an alkaline blend of anodic and cathodic inhibitors based on phosphate, a threshold deposit control agent and a sludge conditioner combined with a bromine pre-cursor. 

In addition, Accepta 2303 offers effective protection to multi-metal HVAC systems.

When used in conjunction with an Accepta activator product, the correct level of “bromine” is released which is essential for the control of microbiological growth in the system.

Accepta 2303 contains no heavy metals and offers the same level of protection over a wide range of temperature conditions in low hardness and low alkalinity conditions.
