Overview

25%-100% DOWTHERM™ SR-1 ethylene glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitors. Solutions have an operating temperature range of -60° F to 250° F (-51° C to  121° C), and the glycol fluid is dyed fluorescent pink to aid in leak detection.

Dow® ethylene glycol-based fluids are less viscous than propylene glycols. Therefore, they generally provide superior heat transfer efficiency and better low temperature performance. However, in applications where toxicity is a concern, propylene glycols are preferred.

This tight head, rectangular container comes with a fixed handle. Our pails are specially designed to allow for mess-free pouring direct from the pail. No need for pumps or siphons! For more container specifications, click here. The filled container is included in the price shown.
