Cryogenic Compressors
Cryogenic Compressors for Technical Gases
PBS cryogenic compressors are designed for the compression of gases such as helium, nitrogen, and argon prior to their liquefaction in scientific and industrial applications. The modular design allows key parameters — pressure, flow rate, and number of stages — to be tailored to specific customer requirements. Multi-stage configurations can be equipped with intercoolers to enhance efficiency, while the use of standardized components ensures fast production, easy maintenance, and reliable service support.
