Compressores de parafuso Water-injected single-stage Screw compressor
Series SW

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

As diverse as your applications

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.

The decisive advantage of the water-injected stages lies in the screw rotors, which are made of high-alloy, corrosion-resistant steel and thus work without deformation even at higher pressures of up to 13 bar. This has significantly reduced the gap dimensions and significantly improved efficiency. The waterinjected compressors of the SW series are directly comparable with the values for oil-injected screw compressors.

AERZEN is also taking an innovative approach to bearings. The highlight: oil-lubricated anti-friction bearings in combination with a special lubricant (ISO VG 46). No use of high-maintenance, grease-lubricated bearings. Your benefit: Permanent lubrication over the entire life cycle of the compressor stage. This eliminates the need to change or top up the oil. An atmospheric gap between the bearings and the compression chamber reliably prevents water from penetrating the oil chamber or oil from entering the water chamber. We offer unrivalled maintenance intervals of at least two years in continuous operation (16,000 operating hours) forthese stages. If service work is required, only the anti-friction bearings and seals ensure to be replaced.
