DOWFROST HD is a Heat Transfer Fluid used in cooling and heating systems, freeze and burst protection of pipes, various deicing, defrosting, and dehumidifying applications. Concentrated formulas requires the addition of deionized water to achieve proper thermal protection. DOWFROST HD has a propylene glycol based fluid that contains 6% specialty formulated industrial inhibitors that help prevent corrosion. Because propylene glycol fluids have low acute oral toxicity, DOWFROST is often used in environmentally sensitive areas but the "HD" formulation is not recommended in areas where contact with food or beverage products could occur.
