SPEEDTHERM R 220 / HEAT TRANSFER OIL MAX 220
SpeedTherm R 220 / Heat Transfer Oil Max 220
SpeedTherm R 220 is an industrial oil that prepared for use in non-pressurized closed circulation heat transfer system operating temperature up to 220° C.
Usage
SpeedTherm R 220 is used in closed heat conductive systems operating without pressure.
Properties
- Maximum Performance Thermal Stability: Mineral oils are exposed to two types of degradation at elevated temperatures.
- The cleavage of the carbon chain formed by the decomposition of hydrocarbon molecules.
- Combine with oxygen in the air oxidation at high temperatures. Speedol heat transfer fluids can be based on two types of effects. It is the high viscosity index for paraffinic.
- Low Evaporation Percentage: The evaporation rate is low.
- Operating Performance at Low Temperature: Operating performance at low temperatures is good.

Matters to be Considered in Operating Conditions
- Oil film temperature of 220 ° C, the heating should be initiated prior to circulation to exceed. Heating should be continued even after the end of circulation for at least two hours.
- This stream should always be turbulent.
- Heating should include refractory material.
- In case of deterioration of the oil pump should alarm system. If possible spare pump should automatically activate or must be manually fast circuit.
- Flame should not be contacted directly with the heater tube.
- The system should not exceed expansion tank temperature 60 ° C.
- First heating up to 110 ° C should be made quite slow. Using ventilation valves should be thrown out of the water vapor and air system.
- The system must be kept under constant control.
