Air-cooled noble gas compressors in the G series for the compression of helium, argon and neon in the 90 – 350 bar pressure range

G series K 22 – K 25: High-pressure compressors for helium, argon and neon in a horizontal design with robust dimensioning for applications such as helium recovery and noble gas bottling

Compressor unit G 22.x for helium and argon

Compressor unit G 25.x / G 28.x for helium and argon, Super-Silent

Compressor unit G 25.x for helium and argon

Very easy to maintain: Thanks to proven BAUER system components

Cost-efficient: Low installation overhead combined with cost-effective operation

Optimum free air delivery rates for your application: For the compression of helium, argon and other noble gases

Comprehensive assurance of spare parts supply: With the global BAUER Service and Support network

The large-scale, high-pressure industrial series by BAUER KOMPRESSOREN impresses as an optimised, gas-tight option for the compression of helium, argon and other noble gases.

Recirculation of blowby and lost gas from the automatic condensate drain into the intake buffer combined with efficient encapsulation of the safety valves effectively minimises gas losses.

Low speeds and optimised grading of the compressors provide the basis for the very best compression ratios for the compression of noble gases.

B-CONTROL MICRO compressor control
The B-CONTROL MICRO is a modern, easy-to-use compressor control with colour display for the control and reliable monitoring of all basic functions. Read more

Helium configuration
The heavy-duty units for helium are characterised by minimum gas losses. Read more

Compressor block
The standard block series is air-cooled and designed for demanding industrial applications. Read more

Super-Silent cladding
Super-Silent cladding reduces the noise level of the compressor unit and enables an exhaust shaft to be used.

B-CONTROL III
B-CONTROL III is BAUER's premium control system for demanding applications. Read More

Colour range
Customer-specific paint finishes in other colours or special composition paints (conforming to corrosivity category C5M, for example) are available alongside the standard BAUER paint finishes.

Start-up configuration
At and above motor power ratings of 75 kW and in conjunction with the B-CONTROL, a soft starter to protect the unit during starting and effectively reduce starting current is used as standard. The technical alternative is soft staring with a frequency inverter. Read more

Monitoring of intermediate pressures and temperatures

Monitoring of pressure and temperature
This add-on module for the B-CONTROL control monitors the pressures and temperatures of all compressor stages. Read more

Treatment systems
BAUER treatment systems for highly compressed air and gases reduce content such as moisture, oil and particles to a permissible level. Read more

Storage systems
Modular high-pressure storage systems by BAUER KOMPRESSOREN are the ideal way to expand a compressor system. Read more

¹ Free air delivery according to ISO 1217, power consumption at maximum final pressure under certain conditions, each valid for helium. Other ambient conditions result in different performance data.
² Max. operating pressure = max. safety valve pressure setting; reduced switch-off pressure.
