GlyEco H80 Heat Transfer Fluid is a heat transfer fluid that is based on organic acid technology. It was designed for multi-metal systems and also systems made entirely or partly of aluminum. Traditional heat transfer fluids are usually phosphate-based, exhibit relatively high pH levels from 9.0-10.7, and protect aluminum at operating temperatures up to a maximum of 150°F (65°C). While these fluids provide good protection for most HVAC systems and other heating/cooling systems made primarily of steel with some copper, cast iron and brass, they can cause great damage to all-aluminum systems operating above 150°F, especially all-aluminum boiler systems.

GlyEco H80 Heat Transfer Fluid’s organic acid-based formulation contains no nitrites, amines, borates or phosphates and provides a pH of 8.0-8.5 in 50% heat transfer fluid. It protects all commonly used metals, including aluminum, up to at least 350°F (176°C), and it is compatible with most plastics and elastomers. GlyEco H80 Heat Transfer Fluid can be used in any heating/cooling system but it is the best choice for high-aluminum-content systems operating above 150°F (65°C). The organic acid salts used in GlyEco H80 Heat Transfer Fluid coat all metal surfaces for protection from corrosion. Azoles are included to supplement “soft” metal protection (copper, brass, solder and aluminum). Organic acid depletion rates are very slow, resulting in a fluid life at least as long as phosphate-based fluids.
