Cryogenic Compressors by PBS

Cryogenic compressors are designed for compressing inert gases.
  • Compact design
  • Option of connecting an intercooler
  • High efficiency
  • Long serviceability and maintenance-free operating period

PBS offers a wide range of cryogenic compressors, all built and assembled in order to meet the standards and demands of our valuable, global customers. We design and build single and multi-stage cryogenic compressors that have been developed to work with various types of gases such as hydrogen, helium, nitrogen, argon and air. While primarily designed to exhaust very low-temperature vapor from liquid helium tanks, the compressors can also work with the other inert gases previously mentioned.

In PBS we deal with each project for each customer individually, which enables us to flexibly respond to requirements in the process of optimizing the particular system in which the compressor is incorporated, as well as to adapt the system to different working media. The compressor design is modular. There are four standard lines from which our customers are able to select their products according to the parameters and impeller sizes. The compressor is driven by an electric engine defined by the customer.

Our cryo compressors have been widely used in research, industry and healthcare since the mid 1990s and some of our most valuable customers include Linde Kryotechnik, and research organizations, such as the European Organization for Nuclear Research (CERN) / Swiss, The European Spallation Source - (ESS) / Sweden, Deutsches Elektronen-Synchrotron (DESY) / Germany and the Rossendorf Research Center / Germany.

One of the advantages of using a cryogenic compressor includes the elimination of wide, bulky pipes which contain heat, thus reducing the possibility of contamination and future blockage of the cryogenic system. Another is that these cold compressors facilitate the simple refrigeration process for the low pressure side of the cryogenic plant cycle by increasing the returning gas to atmospheric pressures while maintaining its cold temperature.

This has all been possibly to PBS's continued dedication to constant research and development in our field.
