Chill Ethylene Glycol (EG) Heat Transfer Fluid

Performance Specifications

This is a heat transfer fluid with an organic acid technology that provides outstanding corrosion protection for copper, brass, solder, steel, cast iron and aluminum. A buffering system neutralizes acids formed by the normal thermal and oxidative degeneration of glycols which helps keep the pH in optimum range. It contains tolytriazole to protect copper, brass and solder from attack and oxygen scavengers for further protection.
