Dry - Running Rotary Screw Compressors

Dry - Running Rotary Screw Compressors

The New Dimension in Oil-Free Compression
With logical component layout and exceptional attention to detail, KAESER 2-stage dry-running rotary screw compressors were designed specifically with the user in mind. Needless to say, there‘s also the peace of mind that comes with Kaeser‘s renowned quality.

Long-Term Efficiency
Compressed air simply has to be available where and whenever it is needed. KAESER 2-stage dry-running rotary 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 created an innovative package concept designed around the 2-stage dry-running rotary screw airend. As a result, KAESER dry-running screw compressors are available, for example, with air-cooling for drive powers up to 355 kW.

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.

Service-Friendly
These versatile systems were engineered for maximum 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.

Proven Airends
At the heart of every Kaeser dry-running compressor lies a tried and tested dry-running, two-stage rotary screw airend. Providing optimum performance and dependability, every airend ensures maximum efficiency throughout its entire service life.

Durable Coating
The rotors are treated using the special “Ultra Coat” process which provides the innovative and durable coating which is resistant to temperatures up to 300 C. Because this cost-reducing coating is highly abrasion-proof, its sealing and protection performance remains consistent even after years of operation.
 
Chromium Steel Rotors
The second compression stage’s rotors are made from stainless steel, which eliminates the risk of rotor seizing and corrosion because an oxide coating cannot form on the rotors.

Easy-Access Coupling
The electric motor directly drives the airend with zero transmission losses via a maintenance-free coupling. As there is no need for complicated disassembly work, the easy Access coupling can be exchanged quickly and easily.
