Brine cooling systems: why chloride attacks the loop, and how to control it
Calcium chloride brine is efficient and severely corrosive. Compare it with modern secondary coolants at the same freezing point, and see how inhibitor programmes work.
Additives
Treatment formulations for industrial circulating cooling-water systems, combining corrosion control, scale inhibition and biological-control functions.

Corrosion and scale-inhibitor formulation
