product description
JY400 is a synthetic heat transfer oil designed for 12℃-400℃ liquid phase heating system or 257℃-400℃ gas phase heating system. Its important characteristics are as follows.
Excellent heat transfer performance - JY400 is a synthetic heat transfer oil with excellent thermal stability and low viscosity at the same time. It can provide effective, reliable and consistent performance in a wide temperature range of 12℃-400℃ . JY400 has high thermal stability in all organic heat transfer media.
Gas-phase heat transfer medium - JY400 is a eutectic mixture composed of 26.5% biphenyl and 73.5% diphenyl ether. It can be used as a liquid-phase heat transfer oil, and can also be used as a gas-phase heat transfer oil in the temperature range of 257℃-400℃ by taking advantage of its evaporation-condensation characteristics.
Low viscosity - JY400 still has a very low viscosity at the lowest temperature of 12℃. However, considering that it will crystallize below 12°C, measures must be taken to prevent operation problems caused by crystallization when used in colder climates.
Excellent temperature control performance ——Because JY400 can be used as a gas phase heat transfer oil, it can meet the requirements of a precise temperature control heat transfer oil system.
Scope of application
JY400It has been widely used in industrial fields, such as: chemical fiber industry; chemical industry.
