The RSW Range
RENNER – oil-free, water-injected, water-cooled compressors
The RSW and RSWF water-cooled screw compressor models were developed for the economical production of oil-free compressed air in the medium output range of 18.5 to 45 kW.A special feature of these utility patent-protected compressors is that the compressor oil used for lubrication, cooling and compression has been totally excluded from the compression process. The most natural of all raw materials has now taken over this task: water. As an ideal heat carrier, it draws the compression heat from the compressor and permanently supplies the water-injected friction bearings.
