A Industrial Thermic Fluid Air Heater is an indirect air heating system that utilizes circulating thermic fluid (thermal oil) as the heat transfer medium to heat process air. The hot thermic fluid flows through a heat exchanger or coil, transferring heat to the air without direct contact. This design allows high air temperatures with precise control while operating at low system pressure. Thermic Fluid Air Heaters are widely used in drying, heating, and process applications requiring stable and clean hot air supply.
