Customized Design

Customized compressors

Our customized line of integrally geared machines can accommodate up to four pinion shafts with up to eight impellers total resulting in impressive pressure ratios which can be achieved in a compact design. Compressors can be designed according to API 617 or API 672 and customer specifications. Driver options depend on process and energy resources and can be electric motor, steam turbine or gas turbine and are suitable for direct turbine-drive or integrated turbine design.

Customized compressors with integrated radial expansion turbine

A variant of the customized integrally geared compressor allows the integration of a single- or two-stage radial expansion turbine as a direct drive option for the compressor. This allows the direct recovery and conversion of energy from pressurized high temperature process gas streams into kinetic energy driving the compressor. Depending on the amount of available energy this drive option can serve as a sole, main or auxiliary driver in combination with e.g. an electric motor or motor generator.
