Dianodic III Control Agent

Corrosion, fouling, and scale can be controlled in neutral or near neutral pH cooling water systems by the Dianodic III halogen stable treatment program. Formulated with the company's proprietary halogen stable azole and a unique blend of calcium phosphate polymer dispersants, Dianodic III can be used with inexpensive biocides such as chlorine without loss of effectiveness. It provides superior performance at elevated temperatures and in the presence of high levels of soluble iron, suspended solids, alum carryover, and calcium hardness.

Benefits include lower operating costs, increased cycles, improved heat transfer, extended equipment life, and minimized downtime for maintenance. One of the company's Dianodic Plus series of halogen stable cooling treatment programs, Dianodic III also reduces copper discharge and guards against pitting corrosion of mild steel.
