Waterline® CI
Phosphorous-free corrosion inhibitor that protects carbon steel in cooling water by forming a persistent, passivating film on steel surfaces. Traditional phosphorous-based cooling water treatment has suboptimal performance under stressed water conditions, fouling from precipitation with calcium, the need for stabilizers, accelerated corrosion of zinc alloys, and the addition of nutrients that promote bacterial growth. Regulations on the limit of eutrophication of surface water makes cooling water with phosphorous more costly.
