Nitrogen Compressors

We delivers high-pressure compressors and the complementary modules for purification, storage and filling.

The sturdy design of stationary high pressure compressors for industrial compression of nitrogen provides a maximum operating safety.

Take profit of our know-how in a wide range of applications, e.g. test systems for air bags and brakes, laser cutting systems, gas injection moulding, offshore platforms and many other nitrogen applications.

Our compressors are designed for your individual application with a high degree of expandability according to your requirements.

Type From To
Inlet pressure atmospheric 25 bar (362 psi)
Delivery capacity 6 m³/h (3,5 cfm) 250 m³/h (147 cfm)
Final pressure 10 bar (140 psi) 420 bar (6100 psi)

We individually calculate compressor and drive power according to your application requirement. In this way, we perform the best possible efficiency and highest economic feasibility for you.
