System design
The units feature a direct coupling, are equipped with vibration dampers and are suitable for installation without a foundation. The gas-tight design ensures loss-free compression to the desired final pressure, making them ideal for the efficient recovery and transfer of noble gases, gas mixtures, and heliox. The water-cooled series is suitable for environments where air cooling is not available and includes an automatic condensate drain for reliable condensate removal.
Compressor block
The BK 23 to BK 52 block series feature a specially engineered crankcase design that ensures even distribution of internal gas forces. Precision manufacturing with tight tolerances and minimal clearance delivers outstanding energy efficiency. Plasma-nitrided cylinders, chrome-plated piston rings, and finely honed surfaces minimize friction and contribute to extended service life. The integrated oil pan, flanged beneath the crankcase, reduces oil consumption and enables installation at angles of up to 30° in any direction.
B-LINK 4G
With an integrated WiFi or 4G router, compressor systems equipped with B-CONTROL MICRO can be wirelessly connected to the B-CLOUD. This enables stable remote access, reliable remote monitoring, and secure data transmission via WLAN or mobile networks. If required, the B-LINK 4G can be installed externally to optimize signal strength. It is designed for use in Europe, the Middle East, Africa, and the Asia-Pacific region.
Options
B-CONTROL III
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.
Monitoring of intermediate pressures and intermediate stage temperatures
This monitoring system is ideal for continuous or fully automatic operation, as well as for systems without constant specialist supervision. If defined limit values are exceeded or undershot, an automatic shutdown is triggered. The current actual values are displayed in the B-CONTROL compressor control system.
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.
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.

What is the IB23 series used for?
The IB23 series comprises water-cooled high-pressure compressors for the compression of air and nitrogen. It is used whenever these gases need to be reliably compressed from atmospheric pressure to high final pressures and supplied in continuous operation. Typical applications include industrial compressed air and nitrogen supply, process gas systems, research and development, test facilities, and applications with permanent high-pressure demand where thermal stability and high operational reliability are required.
What performance ranges does the IB23 series cover?
The IB23 high-pressure compressors achieve final pressures from 90 to 365 bar. Depending on the model, the effective delivery rates range from about 1,000 to 1,750 litres per minute and are suitable for medium to high-capacity continuous operation.
What characterises the technical concept of the IB23 series?
The systems are water-cooled, multi-stage and designed for continuous operation. The bionically shaped, pressure-resistant and gas-tight crankcase prevents leakage, reduces mechanical stress and ensures exceptionally high operational reliability and service life. In combination with multi-stage compression, high final pressures are achieved with a compact and robust design.
