Description
Summit Thermopylae HT Series was designed to meet the tough thermal demands placed on high temperature heat transfer mediums. The synthetic hydrocarbon base stock is well suited to combat the problems of carbon formation on heated surfaces and decreased fluid life as is commonly
encountered with conventional petroleum-based fluids without exhibiting the hazardous characteristics found in aromatic heat transfer fluids. The additional benefits of an extremely low vapor pressure and sub-zero pour points allow for increased efficiency while reducing pressure build-up and
evaporation losses.
