Propylene Glycol, Inhibited - FernFrost HD

FernFrost HD-PG Inhibited is a formulated propylene glycol based heat transfer fluid containing an inhibitor and additive package that controls corrosion of metals, helps prevent scaling and fouling of heat transfer surfaces, and buffers the pH to maintain it in the optimal operating range. It is specifically designed for use in heavy duty applications, such as stationary engines, and refinery and chemical plant processes. We can offer in varying strengths from 25% to our concentrated full strength material. We recommend the use of deionized or distilled water for dilution, if using our concentrate. However, tap water, well water, or city water may be used when it meets your specific quality standards.
