Product Applications

PROGILINE® HT-55 is a synthetic high performance heat transfer fluid. It will withstand demanding temperatures and multiple cycle heating, as well as, cooling conditions in ranges from -15°F (-26°C) up to 550°F (288°C). PROGILINE® HT-55 has higher heat transfer efficiency and significantly improved properties over traditional mineral oil-based products, including thermal and oxidative stability, fluidity and cooling capacity. Most importantly, HT-55 has the built in and unique aromatic properties that enable it to perform at higher bulk outlet temperatures than most of the traditional alkylates and other synthetic hydrocarbon fluids. HT-55 is ideal for heat transfer applications used in a wide variety of industries: plastics molding, specialty chemical manufacturing, natural gas processing and batch process operations.
