Compact, efficient and oil-free turbo compressor systems

Turbo compressors with gas bearings

Ultra-high-speed turbo compressors with contact-free and oil-free gas bearing enable outstanding solutions in terms of compactness, service life and performance. Compared to compressors with standard speeds, our systems are significantly lighter and smaller as well as highly efficient and quiet.

Oil-free, contact-free bearing
Compact design, low weight
Highest performance
Suitable for air, noble and inert gases and many other gases
Custom adaptations possible

Converters for sensorless control

All our converters allow for sensorless control of turbo compressors and motors up to highest speeds. The solution from one single source guarantees optimal compatibility of the converters and the turbo compressors and motors, thus minimizing losses in the turbo compressor or motor and ensuring high converter efficiency and a smooth startup process.

Sensorless control for highly dynamic speed adjustment
Minimal losses in the converter, turbo compressor and motor
Smooth startup process
Gas bearing diagnostics
Custom adaptations possible

Ultra-high-speed motors

Thanks to their high rotational speeds, our motors enable high performance at the smallest volume and weight. This is enabled by rotor designs, windings, materials and proprietary design tools specifically optimized for highest rotational speeds.

Highest power density
Highest speed
Highest efficiency
Low volume and weight

Magnetic-bearing choppers

Our magnetic-bearing choppers can be operated in a vacuum, in air or in a noble gas atmosphere. This allows us to achieve maximum speeds and chopper frequencies. They are used in infrared, laser and X-ray applications and offer highly stable speed control and lock-in functionality.

Maximum speed stability
Operation in vacuum
Minimal vibration emission
Maintenance-free
Custom specific chopper discs and mirror rotors

Oil-free helium recirculation as the key to precise isotope enrichment

Isotopes play a central role in the semiconductor industry, in renewable energies, medical diagnostics and research, and other markets. The enrichment of these isotopes is based on the circulation of high-purity carrier gases such as helium. Stable process conditions, maximum purity, and maximum availability of the systems used are essential.

System expertise

Combination of interdisciplinary technologies into optimized turbo compressor system. This guarantees a system out of one hand with matched components, in particular converter and compressor.

Gas bearing

Oil and maintenance-free operation at highest speeds thanks to a rotor floating on a gas film generated by the rotation of the shaft. Resistant to shocks and vibrations.

Aerodynamics

Transfer of mechanical shaft power to the fluid with radial turbo compressor technology. No pressure fluctuations and a constant mass flow with maximum efficiency.

Electric motor

Permanent magnet synchronous machine technology, providing the required shaft power with minimal copper, iron and rotor losses. Designed for mechanical and rotor dynamic integration with the ultra-high-speed rotor-bearing system. Optimized for series production.

Rotor dynamics

Rotor dynamic design and balancing procedures. Theoretical and practical innovation, knowhow and experience in high-speed operation combined at its best.

Thermal design

The more compact the system, the higher the losses per volume and the bigger the challenge for thermal design and cooling.

Structural mechanics

Reduction of mechanical stresses with optimized geometries and materials. Consideration of manufacturing tolerances and temperature range.

Power electronics

High power density and low losses in converters and motors thanks to a system design and the right choice of topology and modulation methods.

Control systems and software
