Celeroton – Precision Cryogenic Technology for Extreme Environments
Celeroton is your trusted partner for oil-free, vibration-free cold and warm gas compressors and turbo expanders designed to perform at cryogenic temperatures. Our proprietary gas bearing technology uses the process gas itself as a lubricant, ensuring no contamination of the cryogenic environment.
With electric motors and generators that operate directly at cryogenic temperatures—without the need for mechanical feedthroughs or couplings—our systems deliver unmatched reliability and performance. Thanks to our unique direct-drive architecture, we maximize efficiency in both compression and expansion processes.
Our in-house developed control electronics allow for independent operation of compressors and expanders, further optimizing system efficiency and responsiveness.
Key Benefits at a Glance:
- Long-term reliability – Maintenance-free operation over several years
- Truly oil-free – No rotating seals, no risk of lubricant contamination
- Vibration-free operation – Enabled by advanced gas bearing systems
- Ultra-clean performance – Minimal wetted surfaces and carefully selected materials
- Cryogenic resilience – Stable operation even below 20 K
- Cold restart capable – Reliable start-up at cryogenic conditions
- Any-orientation use – Fully functional in any spatial position
Whether for scientific research, industrial gas liquefaction, or space applications, Celeroton delivers precision cryogenic solutions where purity, efficiency, and durability matter most.
