WDAT-SL2 is a liquid chiller fitted with screw compressors with R-134a refrigerant. The EXCELLENCE ST/SC version stands out for its extremely high efficiency levels both with operation at partial and full loads, which makes it a class A unit based on Eurovent's efficiency rating and allows for considerable savings on running costs while preserving the environment. This is possible thanks to the economizer circuit on the compressors, the electronic expansion valves, the tube bundle evaporator and the electronic control fans supplied as standard. Moreover, the ongoing capacity adjustment allows for a quick adjustment of the system's load and therefore an accurate control of the chilled water temperature with a wide operating range. Therefore WDAT-SL2 is the ideal solution for all civil and industrial applications that require high performance levels, operating continuity and lower running and maintenance costs.
