CHILL PROPYLENE GLYCOL FOOD GRADE HEAT TRANSFER FLUID

Performance Specifications

BOSS Chill Propylene Glycol Food Grade heat transfer fluid is used where the fluid may come into accidental or incidental contact with food, beverage products or drinking water may occur. With its special inhibitor package BOSS Chill Propylene Glycol Food Grade heat transfer fluid helps prevent the corrosion of metals, minimizes scaling and fouling of surfaces and buffers the pH to maintain it in the optimum operating range. It is compatible with all common metals in heat transfer systems and is compatible with most plastic construction materials. BOSS Chill Propylene Glycol Food Grade Fluid can be used to provide both freezing protection and burst protection for systems which may be exposed to very low temperatures. This product is pending CFIA approval.
