ABSTRACT:
To reduce the heat present in hot hydraulic oil, the oil is passed through a heat exchanger in heat exchange relation with water. The temperature of the water entering the exchanger is at least 28.degree. C. and the quantity of water circulated through the exchanger is such that the difference between the ingoing and outgoing temperatures of the oil at the heat exchanger is not more than 10.degree. C.
