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.
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.
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.
Separate intake buffer and condensate vessel
In this closed system, the gas released during automatic condensate drainage is captured within the containers and fed directly back into the compression process. The system can also operate without a customer-supplied gas balloon. Its design is based on the combined container concept but consists of two separate vessels. The delivery scope also includes a suction solenoid valve and a compensation line for returning the collected gas to the intake side of the compressor.
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.
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 GB26 series used for?
The GB26 series comprises water-cooled high-pressure compressors for the compression of Helium and Heliox. It is used whenever these gases need to be reliably compressed from atmospheric pressure to high final pressures and supplied in continuous operation, particularly in applications where thermal stability, high gas purity and maximum operational reliability are required. Typical applications include Helium and Heliox recovery, industrial process gas systems, research and development, test facilities and medical-technical applications.
What performance ranges does the GB26 series cover?
The high-pressure versions of the GB26 achieve final pressures of up to approximately 330 bar. The effective delivery rates range from about 2,800 to 3,300 litres per minute and are suitable for large-volume, high-performance continuous operation.
What characterises the technical concept of the GB26 series?
The systems are water-cooled, multi-stage and designed for continuous operation. The bionically shaped, pressure-resistant and fully 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.
How are the GB26 high-pressure compressors controlled and monitored?
The compressors are equipped with the B-CONTROL MICRO control system. This enables simple operation, continuous monitoring of all relevant operating parameters and connection to the B-CLOUD and the B-APP.
What advantages does the B-CLOUD offer?
The B-CLOUD enables central digital monitoring of the system. Operating data and system statuses are available in real time and support condition-based maintenance as well as high system availability.
Which gases is the GB26 series suitable for?
The GB26 series is specifically designed for the compression of Helium and Heliox. The design is optimised for high gas tightness, minimal leakage losses and high gas purity.
What advantages does the water cooling of the GB26 offer compared to air-cooled compressors?
The water cooling enables targeted and efficient heat dissipation directly at the compressor block, particularly at the intercoolers, aftercoolers and valve heads. 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.
Why are the compressors particularly suitable for Helium and Heliox applications?
The compressors of the GB26 series have been specifically developed and optimised for operation with Helium and Heliox. They ensure very high gas tightness, minimal gas losses and high gas purity. By returning blow-by and loss gas from the automatic condensate drain to the intake buffer and by efficiently encapsulating the safety valves, gas losses are effectively minimised. As a result, a leakage rate of less than 0.1 mbar·l/s is achieved.
How maintenance-friendly is the GB26 series?
The compressors are designed for long maintenance intervals and low-maintenance continuous operation. The robust water-cooled large-block design and easily accessible components reduce service effort and minimise downtime.
