Neuenhauser Kompressorenbau Nk (Germany)

NeuenhauserNeuenhauser Kompressorenbau GmbH as part of the Neuenhauser Group was founded in 1986 by taking over the entire compressor manufacturing program of Jos. L. Meyer (Meyer Werft). Since then, air and water cooled piston type air compressors with operating pressures up to 60 bar are developed, manufactured and sold by NK.

In 1995 we took over the air receiver division of Thyssen Umformtechnik.

To serve our customers with a complete product range in the field of starting air, working air and control air systems NK became authorized distributor of TDI TURBO TWINTM Engine Air Starters of the American manufacturer Tech Development (TDI) from Dayton, Ohio.

Since 2002 NK offers working air compressors made by Renner in Germany. The screw type compressors are available in a pressure range up to 15 bar with air receiver and air dryer if required.

NK containers offer mobile compressed air systems ready for installation, which are individually adapted according to customer specifications.

With our product range we are able to support our customers within the marine, the oil and gas industry and plant engineering as reliable partner for design and service of air compressor units and compressed air components.

Proven design – high performance – reliable

NK manufactureses compressors for a multiplicity of applications.
Piston compressors with operating pressures up to 60 bar and flow rates up to 324 m3/h are used to start diesel and gas engines as well as gas turbines or to produce PET bottles.

A further application is the refining of glass in autoclaves.

The compressors are available with electrical or diesel engine drives, direct or belt driven . If required with compressor control.

Additional control equipment is available such as thermostate in compressed air outlet, oil level switch, space heaters, sequence selectors, etc.

All compressors are of modular construction. Up to three compressors can be installed onto a common base frame. If required air receivers can be integrated.

The units are fully tested and ready for installation.

Type approvals of classification societies are available for almost all piston type compressors.
