Details & Features
he air-cooled high-pressure boosters of the PE 20 series are designed for the recompression of compressed nitrogen and provide reliable performance under industrial operating conditions. Generously dimensioned cooling surfaces and a powerful air cooling system enable efficient and long-lasting operation. The robust V-belt drive ensures reliable power transmission and low-maintenance operation. Ideal for industrial applications with existing inlet pressure in compressed nitrogen systems.
B-CONTROL MICRO compressor control system
The B-CONTROL MICRO is a modern, user-friendly compressor control system with a color display that intelligently manages and reliably monitors all basic functions. Interaction between the user and the control system is intuitive and straightforward, with information displayed in clear text. Various languages are available. External signal transmitters can be connected at any time, and operation in a networked system or with an external display is also possible.
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 compressor unit is designed in a space-saving vertical configuration and mounted on a robust base frame with integrated vibration dampers. This allows installation without a foundation and reduces installation effort.
A low-maintenance V-belt drive ensures reliable, speed-independent operation. The service-friendly design provides easy access to all relevant components, allowing maintenance work to be carried out quickly. The integrated condensate drain system ensures automatic and reliable removal of the condensate.
Compressor block
The air-cooled compressor blocks are equipped with intercoolers and aftercoolers as well as oil and water separators after each compression stage, and feature a reliable pressure oil lubrication system. They form the basis for fully automated systems for the compression of air and gases at elevated inlet pressures.
Generously dimensioned coolers and finned cylinders ensure effective heat dissipation even under high load conditions. Fine oil filters, long service intervals, and dynamically balanced drive mechanisms guarantee high efficiency as well as particularly smooth and reliable operation.
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-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.
Super Silent version
The Super Silent enclosure significantly reduces the sound pressure level of the compressor system and enables the connection of an exhaust duct. Its effective sound insulation ensures quieter operation and can also be retrofitted if required.
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.
Oil level monitoring
When the minimum oil level mark is reached, a warning message appears in the control system. This option is particularly recommended for continuous operation and increases the operational safety of the compressor system by providing early information about critical fill levels.
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.

What are PE 20 boosters used for?
PE 20 boosters are used to compress pre-compressed air or nitrogen to higher final pressures. They are suitable for industrial applications where existing inlet pressure is to be used efficiently and increased to high-pressure levels.
What is the difference between a booster and a compressor?
A booster operates with an existing inlet pressure and increases it to the required final pressure. In contrast, a compressor compresses the gas directly from atmospheric intake pressure.
What pressure ranges does the PE 20 series cover?
Depending on the configuration and available inlet pressure, PE 20 boosters achieve final pressures in the range of approximately 90 to 350 bar.
What delivery rates do PE 20 boosters provide?
The PE 20 series covers delivery rates of approximately 1,080 to 1,720 litres per minute. The actual delivery rate depends on the inlet pressure, final pressure and the specific configuration.
Which gases are PE 20 boosters suitable for?
PE 20 boosters are designed for the compression of air and nitrogen. They are specifically intended for industrial applications with increased pressure requirements.
How are PE 20 boosters controlled and monitored?
The boosters are equipped with the B-CONTROL MICRO control system. This allows simple operation, safe monitoring of all relevant operating parameters and connection to the B-CLOUD and the B-APP.
What are the benefits of B-CLOUD?
B-CLOUD enables centralized digital monitoring of the compressor. Operators have continuous access to operating data, can monitor system status, and plan maintenance more efficiently.
Which industrial applications are PE 20 boosters particularly suitable for?
Typical applications include test facilities, gas filling systems, industrial nitrogen systems and applications where existing line pressure needs to be efficiently increased to high-pressure levels.
How maintenance-friendly are PE 20 boosters?
PE 20 boosters are designed for low-maintenance operation and long maintenance intervals. Robust components and a service-friendly design reduce maintenance effort and minimise downtime.
