GlyEco H60 Heat Transfer Fluid is a specially-formulated heat transfer fluid that contains only food grade propylene glycol and food grade or USP dipotassium phosphate and food grade antifoam. All ingredients are classified as GRAS, or generally recognized as safe, by the FDA and acceptable as food additives (Food Additives Regulations, Subparts 182 and 184). It also meets Food Chemicals Codex (Fourth Edition). GlyEco H60 Heat Transfer Fluid can be used in food processing applications in which incidental or accidental contact with food/beverage products or drinking water may occur.
GlyEco H60 Heat Transfer Fluid contains an inhibitor package that helps prevent corrosion of metals, minimizes scaling and fouling of heat transfer surfaces, and buffers the pH to maintain it in the optimum operating range. The inhibitor system is based on a balanced high phosphate formulation. In terms of functionality and performance, GlyEco H60 Heat Transfer Fluid is equivalent to the very best national brands on the market, including Dowfrost*, Ucarfreeze* and Jeffcool* P-200.
Relative to ethylene glycol, propylene glycol has a lower acute oral toxicity. Accordingly, propylene glycol based heat transfer fluids are at least preferable and often required in food processing industry applications in which they may make accidental contact with foods or beverages or where they may incidentally contaminate potable/drinking water. In some municipalities, the use of propylene glycol is required by law or regulation. The propylene glycol used in GlyEco H60 Heat Transfer Fluid is industrial or heat transfer fluid grade; that used in GlyEco H60 Heat Transfer Fluid is food or USP grade. For food industry applications in which the potential for food, beverage or drinking water exists, GlyEco H60 Heat Transfer Fluid is usually the best choice. Propylene glycol also has a higher viscosity than ethylene glycol, which results in somewhat lower heat transfer efficiency and somewhat more difficult cold weather pump start-up for propylene-glycol-based fluids.
