Therm Oil R320
Therm Oil R320
Therm Oil R320 is an industrial oil that prepared for use in non-pressurized closed circulation heat transfer system operating temperature up to 320 °C.
Usage
Therm Oil R320 is used in closed heat conductive systems operating without pressure. It is used safely up to an operating temperature of 315 °C in closed systems and 200 °C in open systems.
Features
- Maximum Performance Thermal Stability:
Mineral oils are exposed to two types of degradation at elevated temperatures. 1) Cracking; degradation caused by the breakdown of the carbon chains of hydrocarbon molecules. 2) Oxidation; oxidation by combining with oxygen in the air at high temperatures. SpeedTherm R320 is manufactured using a base oil of a quality that can withstand both of these effects. - Low Evaporation Percentage:
The evaporation rate is low. - Operating Performance at Low Temperature:
Operating performance at low temperatures is good.
