Overview

25%-100% DOWFROST™ HD propylene glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitors

Solutions have an operating temperature range of -50° F to 325° F (-46° C to 163° C), and the glycol fluid is dyed bright yellow to aid in leak detection.

In applications where toxicity is a concern, propylene glycol fluids are used because of their low acute oral toxicity vs. the moderate acute oral toxicity of ethylene glycols.
