Fluid Guard™ PG 100

Product Information

FluidGuard™ PG 100 is a specially inhibited concentrated propylene glycol product designed for use in closed loop heat transfer systems. FluidGuard™ PG is commonly used in aqueous dilutions from 20 to 50% by volume. At these dilution ranges it offers freeze protection from -7°C and -35°C ( 19°F and -31°F), respectively. The inhibitor system formulated into the fluidGuard™ PG provides excellent corrosion protection for common metals of construction including stainless steel, carbon steel, aluminum, copper, brass, and solder.

Use of FluidGuard™ PG provides for long fluid life, corrosion protection, and leak protection in piping, pumps, valves, fittings, and heating or cooling equipment. Coastal Chemical provides users of our FluidGuard™ products with complete analytical analyses and technical recommendations on fluid quality and applications.

FluidGuard™ PG applications include heating and cooling systems, line heaters, chillers, refrigeration systems, snow melting systems and HVAC systems.
