Integrally geared expanders

The integrally geared expanders are applicable in a wide range of processes such as terephthalic acid  and nitric acid.

  • High and low pressure ratios
  • Single and multi-stage
  • As a separate machine or as an integrated part of an integrally geared compressor
  • Wide range of volume flows

Axial flow

This expander is a standardized multi stage axial flow expansion turbine mostly used in nitric acid and blast furnace top gas recovery applications.

  • High efficiency
  • Stand alone or integrated in a complex train
  • Available also in a single stage design with radial inlet and axial outlet

Axial flow expanders for high temperatures

The MAN Energy Solutions hot gas expander is operating at temperatures  up to 760°C and therefore used in applications such as FCC.

  • Available in single stage design with axial inlet and radial outlet
  • Multistage design with radial inlet and outlet available
  • Stand alone or integrated in a complex train

Move towards carbon-neutrality and economic efficiency

Go for maximum power recovery



In many industrial processes, lots of valuable energy and residual gases can simply go to waste. With the general drive towards carbon-neutrality and demands for ever greater economic efficiency, industrial machinery must run as resource-friendly as possible.


The MAN Energy Solutions expanders are designed especially for energy recovery. They enable utilization of the excess power or heat to drive separate power generation units or turbomachinery in power recovery trains, achieving maximum efficiency.


New processes and solutions are being developed for a carbon-free future. Energy storage and heat pumps are closed cycles containing compression and expansion of diverse refrigerants. Let MAN Energy Solutions be your partner to make your processes come true - ensuring reliable power when needed.


Matching your requirements, MAN Energy Solutions expanders come in single- and multistage design and in axial or radial blade/impeller configurations. Our expanders are either connected to a power generator or directly integrated into a compression train. They are simply tailored to your process.


Range covered: 

  • Power output up to 45 MW
  • Inlet temperature up to 760 °C (1,400 °F)
  • Inlet pressure up to 25 bar
