Dependable performance – up to +115°F ambient temperature
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 +115°F. 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 450 hp.
- Flow rate from 142 to 1790 cfm
- Pressure ranges: CSG models from 60 to 160 psi, DSG and FSG models from 60 to 145 psi
- Models also available with frequency control drives (SFC)
- 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 aluminum-block heat exchanger can simply be swiveled out for cleaning purposes.
Highlights of our air-cooled CSG series
The effective water jacket-cooling achieves an efficiency increase of several percentage points in comparison to oil jacket-cooling. Moreover, the service life of the gear oil is increased to 18,000 operating hours.
Variable cooling air flow rate
Thanks to the innovative fan system, cooling air flow is regulated as needed. This enables optimal adjustment to the corresponding load situation and cooling air temperature.
