Liquefaction plants & cryogenic cooling of technical gases

Operating principle

Cryogenic generators based on the Stirling principle offer the best energy efficiency for on-site refrigeration in the low-temperature range and, thanks to their long-standing industry-proven technology, also the most favourable conditions for high overall cost-effectiveness.

Cryogenic gas technology focuses not only on the extraction, liquefaction, reliquefaction and subcooling of gases, but also on closed cryogenic cooling systems (e.g.) with helium, neon and nitrogen circuits.
