DOWTHERM™ Heat Transfer Fluid

DOWTHERM™ SR-1:

DOWTHERM, Heat Transfer Fluid, Dowtherm SR1, Dowtherm 4000, Glycol, AntifreezeDOWTHERM™ SR-1 fluid is a formulation of 95.4% ethylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed flourescent pink for leak detection purposes. It has an operating temperature range of -60ºF to 250ºF (-51ºC to 212ºC) and solutions in water provide freeze protection to below -60ºF (-51ºC) and burst protection to below -100ºF (-73ºC).

DOWTHERM™ 4000

DOWTHERM™ 4000 fluid is a formulation of 92.4% ethylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed flourescent orange for leak detection purposes. It has an operating temperature range of -60ºF to 350ºF (-51ºC to 177ºC) and solutions in water provide freeze protection to below -60ºF (-51ºC) and burst protection to below -100ºF (-73ºC).

Both fluids are practically odourless and are moderate in acute oral toxicity. They offer excellent freeze and corrosion protection without signifigant reductionin heat transfer performance. These fluids are hygroscopic at low temperatures, which means they attract moisture from the surrounding atmosphere – important in dehumidification applications. both fluids are nonflammable in solutions up to 80% glycol in water.
