DOWFROST’s specialized industrial inhibitor packages are the ultimate choice to combat corrosion in closed-loop water-based systems, including HVAC, process heating, cooling, and the food industry. DOWFROST has been cleared by the FDA for use as food additives and listed as Generally Regarded As Safe (GRAS). The United States Department of Agriculture (USDA) also lists it as chemically acceptable for certain food processing applications.
Here are some applications for DOWFROST:
DOWFROST is made with pharmaceutical grade DOW PuraGuard™ Propylene Glycol USP/EP and, when diluted with purified water, provides freeze protection and low toxicity. Plain glycols or “home brews” can’t neutralize all glycol degradation acids and make water up to ten times more corrosive. Dow’s corrosion inhibitors and additives passivate metal surfaces to prevent corrosion and neutralize degradation compounds, preventing pH drop. Dow’s formula also has thermal-oxidation stability that provides long-term protection.
When it comes to heat transfer fluids, DOWFROST is the top choice for a variety of reasons:
Made entirely from food-grade raw materials compliant with FDA CFR 21 and NSF guidelines, acceptable for use where there is the possibility of incidental food contact
Made with pharmaceutical-grade DOW PuraGuard™ Propylene Glycol USP/EP, ensuring exceptional quality and purity
Robust freeze protection, going as low as -60°F (-51°C), and burst protection to below -100°F (-73°C), depending on concentration
Industrially inhibited heat transfer fluid with an operating range of -50°F to 250°F (-46°C to 121°C).
