B-CONTROL II
The BAUER B-CONTROL II is the advanced version of the B-CONTROL MICRO basic compressor control. Read More
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 control monitors the pressures and temperatures of all compressor stages. Read more
Intake system
The intake system supplies the compressor with air or gas at a suitable and monitored intake pressure. Read more
Intake pressure reduction
IIntake pressure reduction ensures that the compressor takes in the gas at the appropriate pressure. The level of intake pressure reduction is adjusted according to prevailing gas pressure and required intake pressure. Integrated safety valves and pressure monitoring effectively ensure that intake pressure does not fall below or above the permissible level.
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
60-litre condensate vessel
The generous 60 l condensate collection system provides a central collection point for the condensate produced during the compression process inside the compressor. 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
