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. may be used in systems employing either liquid phase or vapor phase heating. Suitable applications include indirect heat transfer.
The unique advantages:
1) Heat stability: 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) The products could be used together with Dowtherm A, Cilotherm-Do,Therm-s-300,Therminol-VP-1, also could be collected for recycling.
