The purest heat transfer fluid

The purest heat transfer fluid

DOWFROST™ is the purest glycol available on the market since it is made with DOW PuraGuard™ Propylene Glycol USP/EP. By contrast, competitor products are often made from recycled or industrial grade glycols, or from glycols derived from bio-renewable sources. DOWFROST has been cleared by the FDA for use as food additives and listed as Generally Regarded As Safe (GRAS). It is also listed as chemically acceptable by the United States Department of Agriculture (USDA) for certain food processing applications.

DOWFROST is the best choice you can make for dependable, long-lasting freeze protection to temperatures as low as -60°F, and burst protection to -100°F depending on the concentration. It also contains specially formulated packages of industrial inhibitors that help prevent corrosion.
