DOWTHERM SR-1 | 55 Gallon Drum
500.00 LBS

DOWTHERM SR-1 Concentrate in drums is an ethylene glycol-based heat transfer fluid that is widely used for secondary cooling and heating applications, for freeze and burst protection of pipes, and for various deicing, defrosting, and dehumidifying applications. DOWTHERM SR-1 Concentrate in drums contains specially formulated packages of industrial inhibitors that help prevent corrosion. Due to ethylene glycol's less viscous properties compared to propylene glycol, they generally provide superior heat transfer efficiency and better low temperature performance and are preferred for most heat transfer applications. In applications where toxicity is a concern, propylene glycol fluids are used because of their low acute oral toxicity vs. the moderate toxicity of ethylene glycols.

    Easy Purchase and quick shipping!

    I am very happy with my purchase from PSC. I tried ordering from a company that I had ordered from before, but they would no longer sell to me because of my distance from them. When I called PSC, they were more than happy to allow my purchase, very professional and helpful, and the shipping was quick. I will stick with them in the future, no doubt about it!
