WL 110.20 is designed for use with the supply unit for heat exchangers WL 110. The setpoint temperature is specified via the touch screen of the PLC in WL 110.
The cold water supply also completes other units that have specific water supply requirements, for example CE 310, ET 262, WL 376 or WL 210. In this case, the setpoint temperature is specified directly on the controller. The cold water supply allows reasonable operation at high ambient and water temperatures.
The unit is equipped with an integral refrigeration system, water tank and circulating pump. In the water tank, a pipe coil acts as an evaporator for the refrigeration cycle and cools the water.
An electronic controller keeps the water temperature constant.
