Compressor trains for industrial gases

The energy required for industrial gas processes is considerable. Highly efficient compressors from MAN Energy Solutions support you in cutting costs and greenhouse gas emissions. We supply compressors for air, dry air, nitrogen and oxygen for your air separation trains.

We have a long history of developing and supplying some of the most efficient and reliable compressors in the markets as well as steam turbine drives and electrical motors. With us, you can obtain your entire production train as well as the necessary maintenance from a single source. Check out our isothermal, axial or integrally geared compressor ranges for more information.


    Capture your unavoidable emissions

    Our modular approach reduces project complexity and lead times, mitigates risks, and keeps down CAPEX. MAN CCUS features modular compression solutions for all available capture technologies.

Schematic image of AIRTRAINUsed in industries ranging from iron and steel to food and medical gases, Air Separation Units (ASU) are employed for many purposes. We have supplied over 80 AIRTRAINs and hundreds of motor-driven compressors for air separation plants worldwide. MAN Energy Solutions delivers AIRTRAINs consisting of steam-turbine-driven main air compressor (MAC) and booster air compressor (BAC) or separate motor driven MACs and BACs. All these solutions meet the customer´s oxygen demand for units between 500 tpd and 4200 tpd. Our comprehensive product range can be tailored to your requirements if desired.


Schematic image of AIRMAXAR-MAX1 – our standardized axial/radial main air compressor can deliver volume flows up to 1.5 million cubic meters per hour, pressures up to 25 bar and exhibits optimum robustness: A piece of equipment you can rely on. When it comes to CAPEX and transportability, AIRMAX trains are very competitive due to the higher speed and power density of the main air compressor (MAC) and steam turbine.

Oxygen compressors

Oxygen compressor in useWe have half a century of experience in designing oxygen turbo compressors and have supplied several hundred casings to the market. We exclusively use single shaft compressors for this purpose, manufactured from non-sparking and ignition-resistant materials for impellers, diffusers and labyrinth strips. Putting safety first also means eliminating dead spaces where particles could accumulate, and an emergency thrust bearing in each casing.
