AERZEN is pushing the technological development of its successful Turbo series and is presenting the first sizes of the new G6 generation with the AT125-0.9S G6, the AT125-1.3S G6, and the AT250-0.9S G6. They set new standards in terms of energy efficiency, turndown, and digitisation and open up new possibilities for future-oriented applications. Another new addition to the portfolio is the AT450-0.9S turbo stage for high volume flows. AERZEN is thus further expanding its position as a technology leader in the range of powerful and efficient turbo solutions.

With the new generation 6 (G6), AERZEN is developing the innovative G5plus design of the Turbo series consistently. At the heart of the package is a new turbo stage with maximum energy efficiency and an unrivalled turndown of up to 1:5. The decisive factor here is the perfectly tuned interaction of impeller, spiral, and all flow-guiding components, whose design is based on complex CFD-supported flow analyses and is precisely matched to the respective performance class. Compared to conventional turbo technology, energy efficiency can be increased by up to 15 %. The control system has also been completely redesigned, and the operating display has been rated IoT-ready. This is complemented by a compact and space-saving design that reduces the machine footprint and facilitates the installation in machine rooms.
New turbo packages of the generation 6
The new Aerzen Turbo AT125-0.9S G6 covers volume flows up to 83 m3/min and the new Aerzen Turbo AT250-0.9S G6 up to 157 m3/min. Both turbo sizes are designed for nominal pressures of 900 mbar. The Aerzen Turbo AT125-1.3 G6 version, on the other hand, achieves a volume flow of up to 70m³/min and a nominal pressure of up to 1300 mbar. A powerful and energy-saving permanent magnet synchronous motor, which meets the future requirements of the IE5 classification (ultra premium efficiency), as well as the particularly aerodynamic design of the turbo impeller and spiral casing, ensures a consistently high overall efficiency. The packages also deliver extraordinary performance in partial load operation.
High efficiency and operational reliability
The modern multilevel VFD technology reduces the power loss in the motor by up to 90 % and thus significantly improves the overall efficiency of the system. Another advantage: is that the VFD eliminates the need for an additional motor choke or a sinusoidal filter, required for standard VFDs. In addition, the air-cooled AERZEN VFD is designed for intake temperatures of up to 50°C. The innovative AERZEN air foil bearing with double coating ensures an increased service life of more than 80,000 operating hours and maximum
reliability. In addition, the turbo blowers operate absolutely oil-free and PFAS-free in process air generation.
IoT-ready for remote monitoring
The new AERZEN Turbo control system is designed for remote monitoring as standard. The system can be activated and used if there is appropriate Internet connectivity on site, for example via LAN, WLAN or mobile radio. It enables transparent monitoring of relevant operating parameters in real time, including differential pressure, volume flow, temperature, speed, electrical power, operating hours, warnings and error histories. This increases transparency and operational reliability and supports integration into networked systems.
New AT450-0.9S turbo stage
The new AT450-0.9S turbo stage complements the turbo series in the upper volume flow range. It is designed for volume flows of up to 300 m³/min and nominal pressures of up to 900 mbar and is the largest size in the current turbo portfolio. Other advantages include increased energy efficiency by up to 15 % and an extended turndown. The innovative twin turbo stage with dual-flow compression is specially designed for higher volume flows and offers significant advantages in terms of efficiency, operational reliability, turndown, and installation space.
