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

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

Stable gas bearings

Celeroton considers the required operating range of its gas bearings in an early phase of the system design and thereby trial-and-error design loops. This allows for fast time to market in customized systems. Furthermore, Celeroton validates the gas bearing stability in serial production. Therefore, at Celeroton, each compressor comes with a gas bearing quality control.

Paper

Cooling of a pixel tracker using gaseous helium

Cooling pixel detectors in experimental particle physics with helium requires the oil-free recirculation of the rare gas. The concept presented in the following paper is not limited to pixel detector applications and can be used to cool any surface with respective heat-densities, only limited by shaping the helium gas flow with the turbo compressor CT-1050-He.
