RCMC-W series screw type water-cooled central chillers adopt Germanmade BITZER with half-closed and twin screw compressors,models with one or two compressors,suitable for using R22 and R407C refrigerants; equiped with high efficiency tube-in-shell type condersor and evaporator ensure stable heat exchange and convenient maintenance; advanced controller with built in microprocessor which has a powerful and encellent performance.

Features:

RCMC-W water-cooledcentralized water-cooling system are main composed of compressor,condensor,evaporator and expasion valve.It is adpoted single-stage vapour compression refergeration system,by the principle of inter con ver sion between gaseous and liquid referigertor,to absorb and release heat.So that,achieving the results of referigeration.
