1. Description
The cooling unit OW 4002 is intended for the cooling of an oil circuit. Oil circulates between
the cooling unit and the heat source. The oil is re-cooled by a water-cooled heat exchanger.
Cooling hoses are connected to the cooling unit via screw and via hose nipples.
Coolant inlet and outlet are marked with symbols: Inlet:

The oil flow is monitored by an adjustable flow switch, the oil temperature by an adjustable
thermal switch. The signals of the flow switch and the thermal switch are available at a po-
tential free safety circuit. The oil pressure is limited by an adjustable bypass valve.
The capacity of the cooling unit depends on the temperature difference between the cooling
water temperature and the oil outlet temperature.
