DOWTHERM™

Heat Transfer Fluids

The Heat Transfer Fluid of Choice

A thermally stable synthetic organic heat transfer fluid designed for high temperature heat transfer applications up to 400 deg C. Compared to hot oils, it exhibits better thermal stability, heat transfer coefficients and significantly better low-temperature pumpability.

  • Excellent stability
  • High temperature process heating
  • Process heating and cooling

Dowtherm brand heat transfer fluids were first introduced in 1929 by Dow for use at high temperatures when the use of steam or hot water is not practical. For example, DOWTHERM™ A Fluid has set the industry standard for over 70 years –precisely because of its excellent thermal stability in applications up to 400 °C (750 °F.)

The fluids transfer heat energy typical from 260 °C (500 °C) to 400 °C (750 °C),where the alternatives direct fire, electrical conduction and hot water/steam are considered unsafe, uneconomical, or incompatible with the process.

As the world’s premier supplier of heat transfer fluids, we’re positioned to serve you globally. So whether your project is in Asia-Pacific, Europe, Latin America, the Middle East, Africa, India, North America, we can supply the fluid you need to make it a success.
