DOWTHERM SR-1 supplier Dow Chemical has manufactured the product with 100% virgin ethylene glycol

DOWTHERM SR-1 serves as an inhibited ethylene glycol based heat transfer fluid manufactured by The Dow Chemical Company. It is a formulation of 95.5 percent by weight ethylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed fluorescent pink for leak detection purposes. Solutions in water provide freeze protection to below -50°C (-60°F) and burst protection to below -73°C (-100°F).

DOWTHERMSR-1 finds its use in closed-loop, water-based HVAC, process heating and cooling, food industry applications within temperature range. It is essentially comprised of Ethylene Glycol at about 95.5% and Performance Additives at about 4.5%. It appears as Fluorescent pink in colour. It exhibits a pH (50% glycol) of about 9.0–10.5 and is of specific gravity about 1.1250–1.1350.

DOWTHERM SR-1 supplier Dow Chemical has manufactured the product with 100% virgin ethylene glycol. The fluid has never been blended with other glycol streams (and do not contain recycled glycol) so as to ensure batch-to-batch consistency. Each product has been specially formulated with heavy-duty industrial inhibitor packages that help in preventing corrosion. The inhibitors are long lasting, easily maintained and replenishable, which means intervals between fluid change outs are extended and fluid expense is minimized.

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 comprises of corrosion inhibitors that have been 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. 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.
