Air Liquide: Majority stake in Cryoconcept

Air Liquide has acquired 80% of the capital of the French company Cryoconcept which specialises in dilution refrigeration. This transaction enables Air Liquide to strengthen its expertise in the field of extreme, or close to absolute zero, cryogenics, to propose a broader offer and accelerate the development of Cryoconcept’s activities.

Founded in 2000 and a spin-off from CEA (the French Alternative Energies and Atomic Energy Commission), Cryoconcept employs 14 employees specialised in the field of very deep refrigeration using dilution refrigeration based on the use of helium-3 and helium-4. This unique technology, which makes it possible to reach temperatures below 10 milliKelvin (close to absolute zero, i.e. -273.14 °C), is essential for fundamental physical research in fields as varied as the detection of dark matter or microscopes to explore the infinitely small. It also appears particularly promising to support ongoing research projects on quantum computers.

With this investment, Air Liquide can now offer its customers a complete range of products and services across the entire cold chain, from 300 Kelvin (ambient temperature) to now less than 10 milliKelvin (-273.14°C). Expert in extreme cryogenics for 60 years, Air Liquide designs and supplies its customers with systems for cold production, liquefaction, storage and distribution of cryogenic fluids, for applications in fields of scientific research, such as the ITER project, and in the aerospace and space fields, such as the Herschel and Planck satellites, or the Melfi space exploration program aboard the International Space Station.
