How Thermal Fluid Systems Work

Sigma Thermal’s Thermal Fluid Systems use a pump to circulate the heat transfer fluid through a heater, where it is heated and then routed to process equipment. The fluid transfers its heat to the process and then returns to the heater for re-circulation. This process operates without the high pressures typical of steam systems, providing a safer, more efficient heating method​.
