Details & Features
The water-cooled I series from BAUER is specially designed for tough industrial use and harsh environmental conditions. Thanks to the targeted water cooling of the intercoolers, aftercoolers and valve heads, most of the heat generated is efficiently dissipated via the cooling water. The robust design ensures high operational reliability. The compressors impress in continuous operation with low oil consumption, low maintenance costs and maximum reliability.
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.
Kompressorsteuerung B-CONTROL SMART
Die B-CONTROL SMART ist eine leistungsstarke Kompressorsteuerung mit erweitertem Funktionsumfang, viel Speicher und IoT-Konnektivität via B-CLOUD. Sie unterstützt den Verbundbetrieb und bietet hohe Performance für anspruchsvolle Anwendungen. Wahlweise mit 3,5" Farbdisplay oder 7" Touchscreen ermöglicht sie intuitive Bedienung und sicheren Fernzugriff – eine zukunftssichere Lösung.
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.
Options
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.
Intake filter monitoring
The intake filter is equipped with a vacuum monitoring system, which is continuously monitored by the B-CONTROL compressor control unit.
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 I52 series used for?
The I52 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 over long periods 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 I52 series cover?
The I52 high-pressure compressors achieve final pressures from 90 to 420 bar. The effective delivery rates range from approximately 4,800 to 6,600 litres per minute, depending on configuration, inlet pressure and operating conditions. This makes the series suitable for medium to high-capacity industrial applications in continuous operation.
What characterises the technical concept of the I52 series?
The systems are water-cooled, multi-stage and designed for continuous operation. The bionically shaped, pressure-resistant and gas-tight crankcase reduces leakage and mechanical stress and ensures high operational reliability and long service life. In combination with multi-stage compression, high final pressures are achieved with a compact and robust design.
How are the I52 high-pressure compressors controlled and monitored?
The compressors of the I52 series are equipped with the B-CONTROL III control system. This system ensures reliable control and monitoring of all relevant operating parameters. Thanks to numerous interfaces, the control system can be flexibly integrated into existing plant and control systems. Operating statuses, messages and faults are clearly displayed and support reliable, efficient and safe system operation.
Which gases is the I52 series suitable for?
The I52 series is specifically designed for the compression of air and nitrogen. The design is optimised for high thermal load capacity, high continuous performance and long-term continuous operation.
What advantages does the water cooling of the I52 offer compared to air-cooled compressors?
The water cooling of the I52 enables targeted and efficient heat dissipation, particularly at the compressor block, valve heads and intermediate stages. This reduces the thermal load on the components, resulting in lower mechanical stress, extended valve service life, reduced oil consumption as well as increased operational reliability and service life. In addition, only minimal room ventilation is required to remove the motor and residual heat.
How maintenance-friendly is the I52 series?
The compressors are designed for long maintenance intervals and low-maintenance continuous operation. The robust water-cooled design and easily accessible components reduce service effort and minimise downtime.
