Sentinel’s SENTI-THERM™ is a synthetic liquid phase heat transfer fluid design for use at moderate operating temperatures in non-pressurized indirect heating systems. It resists chemical and physical change at all temperatures below its maximum bulk operating temperature of 315°C (600°F).

Sentinel’s SENTI-THERM™ major advantages of systems using fluids over mineral oils are greater versatility in operating temperature, better chemical stability, reduced make-up, and closer control of and faster response to temperature change as required by the operation. SENTI-THERM™ heat transfer fluid generally has greater heat carrying capacities and more practical viscosities over its temperature
