Integrally geared compressors and expanders for various gases need to operate reliable at challenging conditions and high speeds. Therefore, we design each integral gear unit tailor made to the requirements of our customer and their application.
We pay special attention to the impeller and casing interfaces as well as the thrust requirements and solutions for each unit in close collaboration with our customer.
Using automated data exchange with our customers (like shaft and bearing data for rotordynamics) we increase efficiency of the design process – for you and for us.
Power generation: Generator driven by expansion turbines for power generation (waste heat, geothermal, etc.)
Oil & gas: Compressors driven by electric motor or steam turbine for gas compression or liquefaction
(Petro-)Chemical: Compressors driven by electric motor for processing of various gases
