Products Specialty:
Phenyl ether-biphenyl eutectic heat transfer fluid is a eutectic mixture of two very stable compounds, biphenyl (C12H10) and diphenyl oxide (C12H10O).
The fluid is dyed clear to light yellow to aid in leak detection.
Could be used in systems employing either liquid phase or vapor phase heating. Suitable applications include indirect heat transfer.
Products advantages:
1) Heat stability: operational experience prove that , have excellent heat stability which could not be substitute by other heat transfer fluids. The recommend oil film temperature highest at 400°C, that is make sure to be applied at gas phase 400°C. If system followed strict design principles, the application could highest at 430°C.
2) Lower vapour pressure:For heat transfer fluids, the most important is property of vapour pressure. The vapour pressure is very low, when at 400°C , the saturated vapour pressure just more than 1Mpa.
3) Low viscosity at liquid phase: are both tolerate 400°C high temperature and very low viscosity, this is beneficial to system process, the resistance is decreased relatively.
4) The good safety property: the flash point at 116°C, it is not belong to fire goods, and steam explosion limit range is very small, from 1.15%(V/V)to 1.99%(V/V).Under normal handling, there is no possibility for explosion dangerous.
5) No corrosion for equipment/reaction vessel
6) Adopt high quality biphenyl made in USA & Japan, and best diphenyl oxide made in China, to be mixed-up and refined strictly
7) The products could be used together with DOWTHERM A, Cilotherm-Do,Therm-s-300,Therminol-VP-1, also could be

Products Specialty:
1)Hydrogenated terphenyls is an excellent liquid-phase high temperature heat transfer fluid with heat stability, anti-oxidation and low vapor pressure, can be used in -7 °C ~345 °C applications and delivers important performance: high thermal stability, high degree of customer satisfaction, reliability and fouling resistant.
Best heat stability, could for long time using within temperature and index tolerance range, and could be recycling.
2)Compared with DOWTHERM, non-toxic, flavorless, pollution-free, small penetrability under high temperature.concretion point is -30°C.
3)Stable viscosity-temperature, less viscosity under daily temperature, better for pumping, the viscosity under high temperature is close near to similar products abroad. The specific heat, thermal 4)conductivity is higher than other similar products, excellent heat transferring.
5)Handling under liquid phase at 340°C condition.
6)No corrosion for facility
7)The products could be as an replacement or mixture using with famous brand HTF model: (USA)Therminol-66,Dowtherm-RP,(France)Gilotherm-TH, (Japan)Therm-S-900
Application:
widely used in the industrial fields including
chemical fiber industry
petrochemical industry
plastic industry
petroleum industry.
