Thermalfluid

The vacuum mixer-dryer shown on the left is designed so that the circulating thermal fluid uniformly heats all product-contact parts. A thermal fluid is a liquid or a gas that is used for heat transfer. It is circulated in closed loops. The goal is to heat or cool equipment and processes in a controlled manner.

Thermal fluids can be water, thermal oils, glycol-water mixtures, or special synthetic heat transfer media. Steam can also be used as a thermal fluid. Low-pressure steam is used when high heat transfer is required at comparatively low temperatures. 

Thermal fluids are used in jacketed vessels, heating coils, heat exchangers, and temperature-controlled mixers. The range of application depends on temperature, pressure, and chemical resistance. Thermal fluids enable uniform temperature control and high temperature stability. They are important for chemical reactions, viscosity control, and product quality.
