DOWFROST™ is a food-grade, inhibited propylene glycol (PG) thermal fluid for heat transfer applications between −50°F and 250°F. It is available in prediluted packages as well.
DOWFROST™ inhibited propylene glycol heat transfer fluid is a best-in-class, food-grade thermal fluid for a wide range of heat transfer applications. DOWFROST™ is comprised of ~96% propylene glycol and 4% corrosion inhibitors to protect and extend equipment life.
All ingredients have been classified as GRAS (generally recognized as safe) by the FDA and are approved as direct food additives. DOWFROST™ is the industry-standard thermal fluid for food processing applications.
DOWFROST™ exhibits effective heat transfer from −50°F to 250°F (−45°C to 120°C) and can offer freeze protection or burst protection down to −60°F.
DOWFROST™ is made from Dow PuraGuard™ Propylene Glycol USP/EP, monopropylene glycol for the highest-quality and longest-lasting performance.
DOWFROST™ is available in a range of prediluted concentrations in DI water and package sizes.

Fiscal budgeting for facility maintenance is truly a tough balance. Too much or too little spending creates a domino-effect for unexpected issues, learn how to better budget with glycol fluids here.
Water is a critical aspect for any glycol-based thermal fluid, the inherent properties of water allow for efficient and effective thermal transfer. But how does water quality affect performance and system equipment? Learn how water quality can affect your system and what you can do to prepare for long-term success.
Heat transfer systems are designed to recover, transfer, and retain heat – this is especially important for systems subjected to extreme cold weather. Learn how the Dow thermal fluids provide freeze and burst protection for winter weather environments.
There are many glycol-based thermal fluids available in the market, but the so-called bargain homebrew solutions carry many hidden costs. Save yourself thousands in repair and fluid costs and learn the true value of the DOWFROST™ brands.
