Product Introduction
SCHULTZ® S750 is the most popular and widely used high temperature synthetic liquid phase heat transfer fluid around the world. It provides long-lasting and excellent performance to systems with operation temperature range of -7℃~350℃. SCHULTZ® S750 has already passed the 350℃ type test conducted by national authority. It will improve your system with higher efficiency and long-lasting reliable operation. SCHULTZ® S750 is the same product as Therminol 66 and can be mixed together in any ratio.
Product Features

Remarkable Thermal Stability —— SCHULTZ® S750 has the highest operation temperature among various kinds of liquid phase fluids. The remarkable thermal stability of SCHULTZ® S750 is derived from its high quality raw material which is generated under 750℃.


High Reliability —— SCHULTZ® S750 is the best choice for systems with operation temperature above 310℃ due to its excellent properties of super long service life and low pressure with high temperature.


Non-Corrosiveness —— SCHULTZ® S750 has non-corrosiveness to general industrial equipments built by iron or nonferrous metals.


Anti-coking Capability —— SCHULTZ® S750 has strong anti-coking capability to against generating solid particles. Most of its degraded products are low molecular substances which are difficult to produce polymers, improving the reliability of system operation.
