COOLGUARD 185X is non-volatile liquid corrosion and scale inhibitor for hard water conditions which has been designed for use in conjunction with biocide treatments, used for control of bacteria of the type considered to be a possible source of Legionnaires’ disease.

It is an alkaline blend of an organic corrosion inhibitor, a threshold deposit controller and sludge conditioner offering protection to multi-metal systems without the requirement of additional specific corrosion inhibitors.

COOLGUARD 185X contains no controversial constituents such as heavy metals or phosphates,
whose use is becoming increasingly restricted. It offers protection over an extended range of pH, temperature and raw water hardness, making an ideal treatment for both building services and industrial application.

COOLGUARD 185X should not be used in conjunction with either chlorine or bromine.

Can be used in conjunction with a Biocide such as Biocide ITA to control microbial growth.

Suitable for
Open Circuit Evaporative Cooling Systems and Air Conditioning Plants
