Dowfrost is a propylene glycol-based heat transfer fluid that contains specially formulated food grade industrial inhibitors to help prevent corrosion. Because propylene glycol has low toxicity, it is often used in applications where food and beverage contact can occur like immersion freezing, packaging carbonated beverages, and fermentation cooling.
Recommended temperature range is from -45°C (-50°F) to 120°C (250°F. Product is colorless and is composed of 96 percent propylene glycol and 4 percent performance additives. It has a specific gravity of 1.050-1.060 in 15/15°C (60/60°F). Dowfrost’s pH is 9.0-10.0 and its reserve alkalinity is 10
ml. (minimum). Product is available in 1, 2, 4, 5, 15, 30, and 55 gallons 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.
