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

Air as a refrigerant: Technology, opportunities, and limitations

Air, as a natural refrigerant, is attracting renewed attention in the wake of stricter climate protection requirements. Its major advantage lies in its environmental compatibility: air has no global warming potential (GWP ≈ 0), is non-toxic, non-flammable, and available worldwide. This eliminates many of the regulatory risks associated with other refrigerants.

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.
