Thermoyle HT

Thermoyle HT

Summit Thermoyle HT synthetic heat transfer fluids are built from a synthetic hydrocarbon base stock 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. It does this without exhibiting the hazardous characteristics found in aromatic heat transfer fluids. The additional benefits of having an extremely low vapor pressure and sub-zero pour points allow for increased efficiency while reducing pressure build-up and evaporation losses. Using  Thermoyle HT also offers exceptional thermal stability - resistant to coking and oxidation, long operating life, low volatility, non-toxic, superior thermal conductivity, low pour point and a wide operating range.

Recommended uses

Summit Thermoyle HT synthetic heat transfer fluids were designed to meet the tough thermal demands placed on high temperature heat transfer mediums.
