Product description
Biphenylbiphenylether mixture thermal oil is a high-temperature gas/liquid dual-purpose high-temperature synthetic organic heat carrier with high thermal stability. It is an eutectic mixture composed of 26.5% biphenylbiphenylether and 73.5% biphenylether.It can be used as a liquid phase thermal oil, or it can be used as a gas phase thermal oil in the temperature range of 257℃-400℃ using its evaporation-condensation characteristics. It is widely used in the CSP solar thermal power generation industry and the chemical fiber chemical industry.
Main features
High thermal stability
Biphenyls produced at high temperatures are a guarantee of good thermal stability
High recognition
The first heat carrier to be launched, its vitality is long enough to show that customers recognize and love it.
Gas-liquid two-phase
Can be used in liquid state at 12-400°, can also be used in gas state at 257-400, to meet higher temperature control requirements
Product packaging
200kg barrel or ISOTank
