Tailored Helium Liquefiers

Custom-engineered cryogenic plants for large scale helium liquefaction. We deliver highly reliable solutions ranging from 300 L/h up to 20 tons per day for global helium transport and liquid helium recycling.

Air Liquide’s custom helium liquefiers (300 L/h to 20 tons/day) combine proprietary turboexpanders and helium-tight tech to ensure continuous, high-yield production tailored to your site.

Advanced technology for continuous operations

Our tailored liquefiers integrate cutting-edge, proprietary technologies to maximize yield and efficiency:

  • Warm compression stations: Featuring lubricated screw compressors and precise oil removal systems, provided as custom or standard solutions depending on your exact liquefaction rate.
  • Advanced cryogenics: The cryogenic sections utilize brazed aluminum heat exchangers coupled with our fully integrated, in-house high-speed turboexpanders featuring frictionless gas bearings.
  • Continuous purification: Systems can incorporate cryogenic purification equipment to guarantee uninterrupted operation.
  • A unified ecosystem: Beyond liquefaction, we seamlessly combine fluid storage, distribution networks, and purification systems into one comprehensive plant architecture.

Reliability & longevity

Industrial-scale liquefaction requires uncompromising robustness. Our tailored plants are built upon a foundation of TRL 9 maturity, utilizing exclusively high-reliability components.

To guarantee the highest quality standards, key manufacturing steps and final assembly are managed entirely in-house. Furthermore, our proprietary "helium-tight" process design ensures that this precious gas is contained with zero losses, guaranteeing decades of reliable service for industrial operations.

  • Easy to use & automated

    While massive in physical scale, these bespoke plants are designed for operational simplicity. By integrating advanced control architectures and automated sub-system, the liquefiers maintain steady-state operation without requiring constant manual adjustment.

    This automated, integrated approach simplifies the daily management of massive helium flows, allowing facility operators to confidently oversee up to 20 tons of daily production with minimal intervention.
