Dowfrost

Dowfrost is a propylene glycol-based heat transfer product, specially formulated as a food grade industrial inhibitor to help prevent corrosion. Because propylene glycol has low acute oral toxicity, Dowfrost is often used in applications where contact with food or beverage products could occur. Specific applications for Dowfrost include: cooling liquid foods, packaging carbonated beverages, fermentation cooling, process heating, and solar heating. Product is available in 1, 2, 4, 5, 15, 30, and 55 gallon containers but custom blends can also be purchased in any size.

Dowfrost HD heat transfer fluid also serves as an industrial corrosion inhibitor with a formulation of 94 percent propylene glycol. The fluid is dyed fluorescent yellow to aid in leak detection. Solutions in water provide freeze protection to below -50°C (-60°F) and burst protection to below -73°C (-100°F). Recommended use temperature range is from -45°C (-50°F) to 160°C (325°F). Suitable applications include: single fluid process and cooling, closed loop, water-based HVAC applications where propylene glycol solutions are preferred or required. (Note: Dowfrost HD is not approved for food use by the USDA and FDA, nor is suitable for food or beverage application.) Product is available in 1, 5, and 55 gallons.
