Cryogenics Department


Cryogenic compressors are designed for compressing inert gases.
  • Compact design
  • Option of connecting an intercooler
  • High efficiency
  • Long serviceability and maintenance-free operating period 
Single or multi-stage PBS cryogenic compressors are primarily designed to exhaust very low-temperature vapor from liquid helium tanks. However, the compressors can also work with other inert gases such as nitrogen, argon, air, etc.

In PBS we deal with each project for each customer individually, which enables ustoflexibly respond to requirements in the process of optimizing the particular system in which the compressor is incorporated, as well asto adapt the system to different working media.  

The compressor design is modular. The casings are divided into four standardized lines for different working media parameters and impeller sizes. The compressor is driven byan electric engine defined by the customer.
