Heat Transfer Fluid

Several material properties serve to modulate the heat transfer between on regions at differing temperatures. Examples include thermal conductivities, specific heats, material densities, fluid velocities, fluid viscosities, surface emission, and more. Taken together, these properties serve to make the solution of many heat transfer problems an involved process.


High Temperature Heat Transfer Fluid

The thermal fluid systems utilizing synthetic organic and silicon based are used in industries as diverse as pharmaceutical production, petrochemicals, manmade fiber production and environmental test chamber. Heat transfer system is to establish the process operating temperature and whether liquid or vapor phase heating can best meet processing needs. These parameters have been specified. It is them possible to select the proper heat transfer agent.
