Oil Free Scroll Air Compressor

KOTECH air’s engineers designed every detail of the two stagedry-running rotary screw airend with maximum efficiency andperformance in mind. As a result, KOTECH air dry-running rotaryscrew compressors, are available with drive powers up to 350 kW.

These versatile systems were engineered for maximum ease-of-use and servicing right from the outset or tne design stage.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.

At the heart of every air dry-running rotary screw 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.

The blasted and bonderised rotors are treated using the special “Ultra Coat” process to produce an innovative and durable coating which is resistant to temperatures of up to 300 °C. because this cost-reducing coating is highly abrasion-resistant, its sealing and protection performance remains consistent even after years of operation.

The second compression stage’s rotors are made from stainless steel, which eliminates the risk of rotor seizing or jamming caused by corrosion.

ln the places where things really needs cooling, i.e. in the second compression stage, coolant flows directly through the walls of the airend housing to ensure best possible heat dissipation and compression efficiency.
