These specially formulated industrial inhibitor packages designed to prevent corrosion are widely used for closed-loop, water-based HVAC, process heating and cooling, and food industry applications. They are manufactured with DOW PuraGuard™ Propylene Glycol USP/EP, a pharmaceutical grade of monopropylene with specified purity greater than 99.8%. Each fluid is specifically formulated with industrial inhibitor packages that prevent corrosion. The inhibitors are easily maintained, long lasting and replenishable, which means intervals between fluid change-outs are extended and fluid expense is minimized.
