All the information you need at your fingertips!
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
Horizontal design
The powerful compressor unit in horizontal design – on a stable base frame with vibration dampers – for installation without a foundation. Read more
Compressor block
The standard block series is air-cooled and has been dimensioned for challenging 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 II
The BAUER B-CONTROL II is the advanced version of the B-CONTROL MICRO basic compressor control. Read More
Explosion protection conforming to ATEX guidelines
Compressor units by BAUER KOMPRESSOREN can be supplied with explosion protection and conforming to ATEX directives.
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 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
