Your initial investment in a heat transfer fluid for a water-based HVAC system pales beside the cost of chillers, pumps, piping, and other hardware components. But your system’s performance, longevity, and long-term cost may well depend on which heat transfer fluid you choose. That’s why you need a fluid that’s designed to stand up to the rigors of HVAC service, protect your system against freeze and corrosion, and provide efficient heat transfer for years with minimal maintenance. For water-based HVAC systems of all descriptions, choose DOWTHERM  or DOWFROST™, fluids. Dow has been the HVAC industry’s trusted source for glycol-based heat transfer fluids for more than 50 years. We offer a full range of industrially inhibited, glycol-based heat transfer fluids specially formulated for demanding HVAC service. Included are fluids offering exceptional freeze and corrosion protection, excellent heat transfer efficiency, and optimal economy in closed-loop heating and air conditioning, thermal energy storage (TES), ground source heat pump, and other water-based HVAC systems

A Note on Dilution Water Quality

For long-term, minimal maintenance operation, Dow fluids should only be diluted with demineralized water that has been distilled, deionized, or passed through a reverse osmosis process to remove potentially troublesome minerals and salts. This is especially important when using DOWFROST ™ which does not contain Dow’s dispersant additive, which helps prevent precipitation of sediment due to water hardness.
Good quality water contains only minute traces of calcium or magnesium (< 100 ppm of total hardness as CaCO3), chloride and sulfate. If good quality water is unavailable for your installation, prediluted solutions of Dow fluids are available
