General Product Description
DOWTHERMTM SR-1 industrially inhibited ethylene glycol-based heat transfer fluid is manufactured by The Dow Chemical Company. Aqueous solutions of DOWTHERM SR-1 fluid are designed to provide freeze/burst and corrosion protection, as well as efficient heat transfer, in waterbased, closed-loop heating and airconditioning systems.
DOWTHERM SR-1 fluid has an operating temperature range of -60°F to 250°F; with fluid freeze protection to below -60°F, and system burst protection to below -100°F. The fluid contains corrosion inhibitors that are specially formulated for HVAC systems to keep pipes free of corrosion without fouling. DOWTHERM SR-1 fluid can be specified for use in new HVAC systems, or as a replacement fluid for use in existing systems. The fluid is dyed fluorescent pink to facilitate system leak detection.
DOWTHERM SR-1 fluid is also suitable for ice storage systems— used either in the closed circulation loop from the chiller to the storage medium; or, in solution with water, in the medium itself. Since DOWTHERM SR-1 contains ethylene glycol which is harmful or fatal if swallowed, direct contact with food or drinking water should be avoided.
