Propylene Glycol, Arctic Protection
ARCTIC PROTECTION – provides burst and freeze protection for chilled water, hydronic and other closed systems at temperatures as low as -100°F. A propylene glycol based antifreeze that is nontoxic, noncorrosive, and can be customized by percent concentration and color.
Ethylene Glycol
ETHYLENE GLYCOL is a heat transfer fluid. It provides freeze protection as low as -100º F. Protects brass, copper, solder, steel, cast iron, aluminum, and other natural metals commonly found in industrial cooling and heating systems. De-ionized water is recommended to minimize unacceptable hardness of minerals.
