Screw compressor SW series

The AERZEN packages of the SW series enable absolutely oil-free compression up to 13 bar with the highest possible energy efficiency and reduced maintenance effort. They are characterised by a unique water purification concept that includes a sealed circuit and integrated treatment: The injected water is "recovered" as condensate by means of a refrigeration dryer after compression. Excess condensate can be disposed of directly without treatment. Furthermore by means of the injection effect the dust particles are “washed out” of the sucked in compressed air. Spores and germs are reduced to a value below the detection limit. The advantages of AERZEN Screw Compressors Series SW at a glance: Increased energy efficiency and better cooling effect thanks to water injection Low operating temperature of maximal 55°C protects the compressor stage and downstream components No oil in the compressed air due to constructive separation of conveying chamber and bearing, thus preventing contamination of the compressed air Use of stainless steel rotors for reliable operation (prevention of corrosion) and optimum efficiency Insensitive compressor design regarding water quality, which saves investment and operating costs and increases system safety Easy and reliable water injection by using the pressure differences within the system, a circulation pump is not required Compressed air is omnipresent in industry and has become indispensable in many applications - be it in chemical/ petrochemical process technology, electronics and semiconductor production, the food and beverage industry, the textile industry, medical technology and many other areas.
