An important item on the agenda is the annual awarding of prizes to companies and their products. RENNER’s oil-free RSWF 26,0 D prevailed against products of other renowned compressor manufacturers, like KAESER, ABAC and Airpol, and won the first prize in the category “Best Product”. The decisive factors were efficiency and sustainability. A special feature of the direct driven compressor RSWF 26,0 D with patented system water treatment is that it requires no oil lubrication during the air compression. The most natural of all raw materials, water, provides cooling and sealing for this machine. Water is an ideal heat carrier which draws the compression heat off the machine and thus ensures low temperatures in the system. In the pharmaceutical and food sectors in particular, these oil-free, water injected screw compressors have been in great demand since they rule out the risk of oil contamination and related production stops.
