Dow high-temperature thermal fluids are premier solutions with decades of proven industry-leading quality and performance. These synthetic and glycol-based fluids deliver long-term reliability and system protection that will save money in the long run and provide your team with peace of mind with a product that truly works.
Dow Chemical has a long-established history as the industry standard in the highest-quality thermal fluids for process heating and cooling. Dow continues the tradition of premium-performance solutions with their range of high-temperature heat transfer fluids, providing you with a product you can rely on. The high-temp fluid portfolio consists of synthetic organic and silicone-based thermal fluids in the DOWTHERM™ and SYLTHERM™ product lines.
A wide range of applications require precise thermal control, and dozens of thermal fluid solutions exist—but not all are created equal. It can be easy to be fooled by some marketing jargon or a cheap sticker price promising "equivalent" performance, but rest assured, there is no equivalent for a Dow fluid. The portfolio of fluid solutions from Dow provides incredibly robust thermal stability and a temperature range from −100°C all the way up to 400°C. From jacketed reactors to heat exchangers and more, the SYLTHERM™ and DOWTHERM™ products provide a stable fluid for temperature control across a wide array of applications.
