Inert Gas Compressors

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

High performance complete solutions for reliable compression, purification, storage and recovery of inert gases such as helium and argon. This compressor series provides economic efficiency to the maximum due to loss-free compression by means of returning condensation and leak gases.

Take profit of our many years of experience in planning and construction of special systems for applications such as helium recovery, filling plants and different test plants as well as various other helium applications.

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.
