Thermal fluids, also commonly known as heat transfer fluids, HTFs, hot oils or thermic fluids, are designed to provide accurate, uniform temperature control to process operating units while still maintaining low system pressures. 

A compilation of Process Heating articles from 2019.

Specifications for Calflo, Petro-Therm and Purity FG HTF heat transfer fluids, manufactured by Petro-Canada Lubricants Inc., have been added to aspenOne Engineering software. The companies expect the additions to the Aspen HYSYS and Aspen Plus modeling software to provide engineers with a range of solutions when designing a heat transfer system.

Water is nature’s heat transfer fluid, a liquid used since the dawn of time to heat and cool. It freezes at 32°F (0°C) and boils at 212°F (100°C). To extend the liquid range, other chemicals are added such as ethylene and propylene glycol.

Heat transfer fluids come in many different chemistries, from water-based to organics, depending on the application. 

January marks the return of our annual Equipment Overview on Heat Transfer Fluids, which includes all of the fluid characteristics needed to select a heat transfer fluid for industrial thermal processing.

Giving careful consideration to heat transfer fluids provides optimal system performance. Gain insight into common problems with industrial thermal fluid heating and get takeaways you can put into action in your plant.

Heat transfer fluid systems are used around the globe to provide indirect heating and cooling to process users.
