Fluid Guard™ EG50 & EG 100

Product Information

FluidGuard™ EG 100 is an inhibited ethylene glycol as an industrial coolant and heat transfer fluid. FluidGuard™ EG 50 is an pre-blended 50% solution in de-ionized water. The inhibitor system is designed to protect brass, copper, solder, steel, cast iron, aluminum, and other natural metals commonly found in industrial cooling and heating systems. Use of FluidGuard™ EG provides for long fluid life, corrosion protection, and leak protection in piping, pumps, valves, fittings, and heating or cooling equipment. Coastal Chemical Co., LLC provides users of our FluidGuard™ products with complete analytical analyses and technical recommendations on fluid quality and applications.

FluidGuard™ EG is commonly used in an aqueous dilution from 20 to 60% by volume. These levels provide freeze protection between -9°C and -46°C(15°F and -50°F), respectively.

FluidGuard™ applications include heating and cooling systems, line heaters, chllers, refrigeration systems, snow melting systems and HVAC systems. FluidGuard™ EG is not suitable for use where contact with food or potable water is possible. These systems require FluidGuard™ PG USP grade products.
