In the absence of cooling-water infrastructure, air-cooled oil-free compression rotary screw compressors ensure exceptional compressed air supply reliability – even in ambient temperatures as high as 45 °C.
There’s also plenty of power: thanks to innovative and intelligent system design, air-cooled oil-free compression rotary screw compressors are available up to 355 kW.
- Flow rates from 3.2 to 50.8 m³/min
- Robust stainless steel-aluminium cooler combination
- Also available as a peak-load model with variable-speed control and frequency converter (SFC model versions)
- Also available with integrated i.HOC rotary dryer (CSG-2 & DSG-2 series)
- Heat-use made easy:
Thanks to radial fans with high residual thrust, the heated cooling air can usually be used straight away for interior heating without additional auxiliary fans.
- Energy-efficient details as standard:
In standby mode, the temperature-controlled Kaeser standstill fan reliably dissipates residual heat – which means the main fan can be switched off!
- Exceptionally maintenance-friendly:
The first and second stages of the aluminium block heat exchanger can simply be pivoted out for cleaning.
Compressed air simply has to be available where and whenever it is needed. KAESER dry compression rotary screw compressors are therefore built to last and to ensure many years of dependable performance. Comprising tried and tested components that have been developed as a result of KAESER’s near century of experience in mechanical engineering, KAESER compressors deliver the durability and compressed air availability to meet even the toughest of demands.
Innovation you can trust
Using all of the advantages that KAESER’s advanced Research and Development Centre in Coburg has to offer, KAESER’s engineers designed every detail of the twostage dry compression rotary screw airend with maximum efficiency and performance in mind. Further additional system features include the use of fi bre-free pulse dampers and, with water-cooled compressor packages, an integrated heat recovery module.
Efficiency as standard
KAESER quality and expertise really count when it comes to those all-important total system costs for asset investments such as compressors or complete compressed air supply systems. Lowest possible compressed air costs and maximum availability can be guaranteed only through a combination of perfect interplay between energy efficiency and service / maintenance, and by viewing the compressed air supply system as a whole.
These versatile systems were engineered for optimum ease-of-use and servicing right from the outset of the design stage. Fewer wearing parts and the use of premium quality materials ensure reduced maintenance requirement, longer service intervals and extended service life. Excellent component accessibility as a result of generously sized maintenance doors and a swing-out cooler are just some of the features that make servicing so effortless.
Energy-efficiency: the essential requirement
Investment and service costs account for only a small part of a compressor’s total life-cycle costs. Since energy accounts for the lion’s share of those costs, it’s wise to save with KAESER Life-Cycle Management. KAESER has been committed to minimising your energy costs for compressed air production for over 40 years. We also have the bigger picture in clear focus when it comes to service and maintenance, as well as maximum compressed air supply availability.
