Water Cooled Rotary Screw Chillers – WX

The WX060SSY to WX125SSY High Efficiency Screw Compressor Chillers are easily installed, can be expanded and serviced in place with shutting down the rest of the system. Having the smallest plant foot print, they are the ideal water cooled condenser for your cooling needs. They feature single refrigeration circuits and a smart microprocessor-based with a door mounted key pad display with icons showing the chillers operation and displaying operating and fault conditions in English.
