Heat Transfer Fluid



A heat transfer fluid (HTF) is a liquid or a gas that transports heat from one component to another component in any process requiring heating or cooling or simply to maintain a constant temperature.

The desirable attributes of a heat transfer fluid are non or low toxicity (food grade), low viscosity at low temperatures, high specific heat and thermal conductivity, environmentally friendly, high flash point (or non-flammable) and economical.



  • Cooling of a reactor with an exothermic reaction
  • Maintaining a very low-temperature climactic chamber or wind tunnel
  • Utilizing solar energy to make hot water
  • Cooling an engine
  • Maintaining the ice temperature in an ice rink, cold storage and cooling high power electronics.
