Thermal Fluids

Duratherm offers a wide range of thermal fluids (heat transfer fluids) for just about every application and for use anywhere from -84ºC (-120ºF) right up to 338ºC (640ºF). Most are non-toxic and non-hazardous, some even food grade but all are highly efficient, clean running and long lasting.
