Product Introduction
SCHULTZ®380 is a liquid phase heat transfer fluid featured with outstanding high thermal stability and its maximum operating temperature is as high as 380℃. Comparing to other super high temperature heat transfer fluids, SCHULTZ® 380 has lower pour point, which decrease the cost of system ant-freezing facility. SCHULTZ®380 is the same product as Therminol 72 and can be mixed together in any ratio.
Product Features

Remarkable Thermal Stability – With the remarkable thermal stability, SCHULTZ ®380 can provide stable and reliable heat transfer in -10℃~380℃ for a long-term, making it a significant liquid phase heat transfer fluid.


Low Vapor Pressure – Featured with low vapor pressure, the saturated vapor pressure of SCHULTZ ®380 in 380℃ is only 0.62MPa.


Good Operation Cost – There is no need to worry about the fluid solidification during system shutdown in normal temperature as SCHULTZ ®380 has lower pour point than other super high temperature heat transfer fluids, decreasing the cost of anti-freezing facility of system.


Anti-coking – SCHULTZ ®380 is synthesized by chemical refining, effectively reducing the formation of system coking and solid particles, guaranteeing the operation safety.
