Tailored helium refrigerators

Custom-designed cryogenic plants for science applications. We deliver highly specialized refrigeration systems providing from 1,000 W to 25 kW of cooling power (equivalent at 4.5 K).

Large-scale research facilities, such as particle accelerators, tokamaks, synchrotrons, or stellarators, require massive and highly specific cryogenic capabilities. Our tailored helium refrigerators provide ultra-reliable cooling architectures.

Custom-engineered cryogenic performance

Every science project has its own specificities. We are able to offer custom-design refrigerators to precisely meet the specific refrigeration needs of each customer's application.

Massive cooling power: Scalable capacity ranging from 1,000 W to 25 kW (equivalent power at 4.5 K).
Extreme temperatures: Capable of delivering helium down to deep cryogenic temperatures, including 1.8 K, 4.5 K, 80 K, or any intermediate temperature required by your instruments.
Flexible fluid states: Systems can be engineered to deliver helium in the exact required state, whether liquid or supercritical.

Complete cryogenic ecosystems

A tailored refrigerator is often the heart of a much larger cryogenic infrastructure. Beyond the core cooling unit, Air Liquide possesses the system integration expertise to design complete, end-to-end fluid management networks.

If needed, our engineering teams can seamlessly incorporate comprehensive fluid storage tanks, complex distribution lines, and high-purity helium purification systems directly into your facility's architectural design, providing a single-source solution for extreme cold needs.

Extreme reliability & controlled OPEX

When operating major experiments, equipment downtime is simply not an option. By utilizing a strict selection of high-reliability industrial components, these customized systems require significantly reduced maintenance over their decades-long lifespans. This robust engineering guarantees maximum availability for researchers and ensures a strictly controlled operating cost for facility managers.

Powering global Big Science

Air Liquide’s bespoke cryogenic engineering powers the frontiers of human knowledge. Our tailored helium refrigerators are the technology of choice for the world's most demanding physics collaborations. Multiple massive, custom-built systems have been successfully delivered and are currently operating at prestigious institutions including CERN (European Organization for Nuclear Research), ITER (International Thermonuclear Experimental Reactor), and SLAC (Stanford Accelerator Laboratory).
