The B-CONTROL III is the premium control system for complex applications. Its 7-inch touchscreen display provides a user-friendly visualization of all operating data. Features such as a data logger, USB interface, Remote HMI, and protocols including OPC UA, Modbus, and CAN bus are integrated. The control system supports up to four compressors in a network and can be expanded flexibly.
Soft start
For a smooth start-up of your system, the use of a soft starter is recommended, as it significantly reduces the starting current. From a motor power of 75 kW and above, this function is included as standard in combination with the B-CONTROL control system. Alternatively, a frequency converter can be used. In addition to enabling soft starting, it allows the delivery rate to be adjusted according to actual demand, helping to reduce energy consumption – for maximum efficiency and operational reliability.
Intake filter monitoring
The intake filter is equipped with a vacuum monitoring system, which is continuously monitored by the B-CONTROL compressor control unit.
B-CLOUD & B-APP
With BAUER B-CLOUD and the B-APP, users can keep an eye on their compressor system at all times, even remotely. Operating data, maintenance instructions, and status messages are transmitted and visualized in real time. This increases transparency, simplifies monitoring, and supports optimized maintenance planning. In addition, the stored operating data in the B-CLOUD is available for later analysis and system performance optimization. If the condition of your compressor system changes, B-CLOUD or B-APP will notify you immediately – by email or via push notification straight to your smartphone.
B-LINK
Wi-Fi and 4G routers enable the wireless communication of the B-CONTROL MICRO with the B-CLOUD. They establish a reliable Wi-Fi or mobile network connection, allowing secure remote access to the compressor system.
Intermediate pressure gauge
Analog pressure gauges are installed at appropriate points of the compressor system and allow for easy monitoring of operating pressures. They support diagnostics and simplify maintenance work on the system.
Pre-lubrication pump
After extended downtimes, the bearings are automatically pre-lubricated to ensure safe start-up. This process is managed by the B-CONTROL control system.
Intake device and intake buffer vessel
The intake device supplies air or gas to the compressor at a monitored intake pressure. If predefined pressure limits are exceeded or not met, the system automatically shuts down for protection. To minimize pulsations in the intake area, the use of an intake buffer tank is recommended.
Condensate collection system 60 l
The large condensate collection system centrally collects the condensate generated during compression. An integrated float switch reliably monitors the fill level. The silencer and filter unit reduce noise and prevent unpleasant odors in the working environment.
Plate heat exchanger set
The plate heat exchanger enables the creation of a separate, closed cooling water circuit for the compressor. This is especially important in open cooling systems that use river water, seawater, or open cooling towers. By isolating the compressor from the primary cooling source, the system ensures a consistently high and reliable cooling water quality for compressor operation.
Heat exchanger set
The set includes an air-water heat exchanger that allows water-cooled compressor units to operate independently of an on-site water supply.
