Cooling water treatment agents
Cooling water treatment agents are added to cooling water to prevent pipelines and equipment from corrosion, scaling, fouling and microbial problems. They can improve cooling efficiency, reduce water and power costs, and prolong equipment service life. They can also eradicate the growth of Legionella in air conditioning cooling water system.

Corrosion inhibitors are used to prevent various types of corrosion and solve the corrosion problems.
Scale inhibitors are used to prevent the build-up of inorganic deposits, therefore eliminates scaling. Scale is formed due to deposition of calcium carbonate, calcium sulfate, silicates, iron and magnesium compounds.
