KOSTChill™ PG HD is a fully formulated virgin propylene glycol based heat transfer fluid containing an inhibitor and additive package that controls the corrosion of metals; helps prevent scaling and the fouling of heat transfer surfaces, and buffers the pH to maintain it in the optimum operating range. Used for heavy-duty applications, KOSTChill™ PG HD has a recommended operating temperature range of -50° F to 325° F when mixed with appropriate water concentrations. It provides both freeze and burst protection for systems exposed to very low temperatures.

Benefits:
• Fluid is dyed fluorescent pink for leak detection purposes
 • Silicate free
 • Meets the Heat Transfer Fluid ASTM D8039 requirements standards for multi-metal corrosion protection and for D1881, foam tendency testing for ready-to-use heat transfer fluids
• Available in dilutions ranging from 25% to 70%, a minimum of 30% to meet ASTM protection standards
 • Operating temperature of -50° F to 325° F

KOSTChill™ PG HD inhibited virgin propylene glycol-based heat transfer fluid is manufactured with the highest quality raw materials, specially formulated with a state-of-the-art inhibitor package that prevents corrosion, which minimizes fluid expense and extends fluid life. Please note that we recommend diluting only with RO (reverse osmosis) or distilled water to maintain corrosion protection.
