Optigard BMC 540

Closed Circuit Corrosion Inhibitor

OPTIGARD BMC 540 is a clear, specially formulated, chromate- and phosphate-free corrosion inhibitor used to prevent pitting and galvanic corrosion in closed-circuit heating and cooling systems.
Because it is chromate- and phosphate-free, it can condition closed-circuit heating and cooling systems without any risk of contamination.
It is safe to apply blowdown directly to water sources such as rivers and lakes. It was specifically developed to control pitting and galvanic corrosion, particularly in systems containing multiple metals.
It protects the system from corrosion.
It is safe to use with alcohol- and glycol-based antifreezes.
Because it is chromate- and phosphate-free, it is environmentally friendly.
It is easy to use and economical.
