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
Start-up configuration

Start-up configuration
At and above motor power ratings of 75 kW and in conjunction with the B-CONTROL II, 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 pressure and temperature
This add-on module for the B-CONTROL II control monitors the pressures and temperatures of all compressor stages. Read more

Intake system
Intake system

Intake system
The intake system supplies the compressor with air or gas at a suitable and monitored intake pressure. Read more

Intake pressure reduction
Intake pressure reduction

Intake pressure reduction
Intake pressure reduction ensures that the compressor takes in the gas at the appropriate pressure. Depending on the prevailing gas pressure and the intake pressure required, 1-stage or 2-stage intake pressure reduction is used. Integrated safety valves and pressure monitoring provide an effective means of ensuring that the permissible intake pressure is not exceeded or undershot.

Intake buffer vessel
Intake buffer vessel

Intake buffer vessel
To effectively prevent pulsations in the intake area, an intake buffer vessel is installed between the compressor and the upstream gas supply networks and/or control equipment. Read more
