Cooling Tower Passivation

Corrosion of metal can be prevented through the use of an effective protective barrier. It is therefore extremely important to properly prepare a surface to receive protection, then quickly and completely apply the protecting media to effectively protect that surface. Preparing the surface may be called pre-treatment or passivation.
