RAVENOL Wärmeträgeroel 68 is mineral oil based heat-transfer oil which is suitable for industrial operation of closed heat transfer systems.
RAVENOL Wärmeträgeroel 68 offers high thermal conductivity, combined with high thermal stability and high resistance to oxidation.
RAVENOL Wärmeträgeroel 68 is an excellent heat transfer oil that meets the specified requirements.
Application Note
RAVENOL Wärmeträgeroel 68 is particularly suitable for use in closed heating systems. The maximum flow temperature should not exceed 320°C. The maximum oil film temperature is 350°C. The direct contact of the oil with the ambient air must be avoided, as this would accelerate aging. We recommend cleaning of the entire heat transfer system before each new filling. A non-maintenance justice purified plant achieves no optimum efficiency.
Characteristics
- A very stable and excellent viscosity behavior
- High thermal conductivity
- High oxidation stability
- Protection against corrosion
