Rotary compressor CSG series

airelectrically-poweredstationary

In the absence of a cooling-water infrastructure, air-cooled, oil-free compression rotary screw compressors ensure exceptional compressed air supply dependability – even in ambient temperatures up to +45 °C. There’s also plenty of power: thanks to innovative and intelligent system design, we can provide air-cooled, oil-free compression rotary screw compressors up to 355 kW. Durable, stainless steel-aluminium cooler combination Also available as a peak-load model with variable speed control and frequency converter (SFC model versions) Also with integrated i.HOC rotation dryer Your benefits Heat-use made simple: Thanks to radial fans with high residual thrust, the heated cooling air can normally be used straight away for space heating without need of auxiliary fans. Energy-efficient in every detail: In standby mode, the temperature-controlled Kaeser standstill fan reliably conveys residual heat away – meaning the main fan can be switched off! Exceptionally maintenance-friendly: The first and second stages of the aluminium-block heat exchanger can simply be swivelled out for cleaning purposes.
