    • In an oil conditioner comprising: a coolant oil circulation circuit (8) through which a coolant oil of a machine tool (1) is circulated by an oil pump (12); a refrigeration circuit (20) formed by interconnecting, in the order given, a compressor (15), a condenser (16), a pressure reducing mechanism (17), and an evaporator (18) for cooling the coolant oil in the coolant oil circulation circuit (8) by heat exchange with refrigerant; and an inverter (28) for controlling the operating frequency of a motor (14) of the compressor (15), the output from the inverter (28) is switched to a motor (11) of the oil pump (12) during the time the compressor (15) is out of operation so that the amount of coolant oil that the oil pump (12) circulates is made variable, and the amount of coolant oil that the oil pump (12) circulates is reduced when the amount of heat produced in the operation of the machine tool (1) decreases because, for example, the machine tool (1) is stopped, for reducing wasteful consumption of energy by the oil pump (12) . Energy savings are achieved through the oil pump (12).
