DescripTion
The WL 3000 cooling unit is intended to remove heat from a liquid circuit. The coolant can be either water or a
mixture of water and water-glycol (antifreeze). Water circulates in a closed loop between the ambient cooling system
and a cold plate at the heat source. Heat is removed from water by an air-cooled heat exchanger. The capacity
of the cooling unit is dependent on the temperature differential, which is defined as the difference between the
ambient temperature and the water outlet temperature. The cooling unit is designed to remove 3000 W of heat at
a temperature differential of 11.5°C. The maximum forward pressure is limited by a bypass valve, which has been
integrated into the pump. The coolant flow is controlled by a flow switch that opens when flow falls below a set
rate. Cooling hoses supplied by user are connected to threaded nozzle that can accommodate a 9 mm hose ID.
Note:
Flow switch and bypass valve are adjusted at factory according to specifications in this document.
