Versatility included

If your industrial process requires the compression of large quantities of air, oxygen or nitrogen, an isothermal compressor could be the right choice.

The most powerful compressor for air separation applications in its class

Long tried-and-tested in the field, the design has proven operational excellence in air separation and oxygen compression.

Its principal design allows the isothermal compressor to work with air, nitrogen or oxygen. The reduced driving power saves energy. Several frame sizes are available for a wide range of flows, mainly used in air separation or oxygen plants. Overall, this is a simple compact machinery design, with a few interfaces for easy integration into a process plant.

Take our RIKT model: It is very efficient at compressing non-toxic or non-explosive fluids and usually operates as the main air compressor in air separation units. However, it could potentially be used in compressed air energy storage facilities or any other process requiring large quantities of air.

The isothermal compressor design can be combined with other compressor lines and drive types in many train variants. We provide full train expertise including the plant integration engineering.

How you benefit:

  • Maximum reliability and low energy consumption
  • Compact design and low space requirements
  • Sophisticated aerodynamics and low noise emissions
  • Coolers integrated in compressor casing
  • Service- and installation-friendly design
