WOLF HEAT TRANSFER OIL ISO 32

This is a heat transfer oil based on a specifically refined mineral oil with exceptional oxidation stability and very high resistance to thermal decomposition.

This oil is recommended for heat transfer systems in generators, equipped with an expansion vessel and a proper circulation speed, where the maximum oil temperature does not exceed 315°C. The maximum film temperature is 340°C.

This product is characterized by exceptional stability to cracking or breaking down of the hydrocarbon molecules thus avoiding losses via volatility or the formation of polymers. It is also very resistant to oxidation and viscosity increase.
