25%-100% DOWTHERM SR-1 Inhibited Ethylene Glycol in 55 Gallon Drum

If you require a lift gate for delivery, click here to add our lift gate option to your order. Only one lift gate fee is required per order.

Overview

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. 

How to Buy Glycol

DOWTHERM SR-1 is ready to ship in concentrations ranging from 25% to 50% and 100% concentrated. Need help determining your required glycol concentration? Try our helpful glycol calculator tools!

The high purity glycol fluid is mixed with purified, deionized water at our in-house facility. Our heat transfer specialists can also custom mix concentrations outside of what is available below. Contact us to request a custom premix.
