The main cost of a compressor is represented by the expense for energy, which is much higher than the purchase of the machine itself.
Screw Compressors with the energy-saving SIGMA PROFILE
Basically, you can produce the same air flow both with a small group rotating screw at high speed or with larger groups at slow speed. In general the latter, if well designed, are more efficient and, using the same power, they deliver more compressed air.
Kaeser realizes screw groups with a low number of revolutions and the use of optimized rotors. Thanks to considerable energy savings each screw compressor Kaeser will be easily amortized in a short time.
