Aerzen Screw Compressor Stages VMW oil-free with water injection
Special bare shaft stage for stationary air compressors
Screw compressors with water injection cooling become more and more accepted for the generation of absolutely oil-free compressed air, whereas the function of oil is mostly taken over by water. The rotors of the VMW water stage are made of high-alloyed noncorrosive steel with a very high accuracy in contour and profile even at higher pressures.
Despite singlestage operation mode the VMW water stages can generate pressures up to 13 bar. As it has been standard up to now high investment costs for oil-free compressor plants are now decreasing because of the application of the new Aerzener compressor stage with water injection. The VMW stage is the core of these plants. Drive is provided by an electric motor in combination with a frequency control.
The VMW water stage is supplied as component to manufacturers of air compressors who manufacture the accessories resp. the plant components (cooler, base frame, control etc.) themselves resulting in the following advantages:
• Increased efficiency for the generation of compressed air
• Protection of the components due to lower operating temperature
• Oil-free compression
• A thousand fold well-proven technology for oil-free compressor stages
• Optimized efficiency because of the use of high-quality materials
• Insensitiveness with regard to water quality
• Reduced investment costs for the components of the compressor package
