Industrial nitrogen inerting solutions

Deliver continuous, on-site N2 supply for inerting needs, with our compact membrane technology. Achieve uncompromising reliability for your inerting needs with pressures up to 35 barg and 99.9% purity.

Traditional inerting is costly. Our advanced, low-cost membrane generator systems provide reliable, autonomous, on-site N2 supply, eliminating logistics for all industrial needs, including food and beverage.

On-site nitrogen: A cost-effective supply for industrial processes

Air Liquide’s membrane technology is the highly versatile choice for food, agriculture, and manufacturing environments. Instead of relying on expensive external gas deliveries and complex cylinder management, our Nitrogen Production Units (NPUs) offer a fully autonomous 'plug and play' solution. Utilized in over 2,000 locations worldwide, our systems can be finely tuned to deliver exact purities from 95% to 99.9% (at up to 35 barg) to perfectly match your specific process needs.

Core benefits of our membrane solutions

  • Optimized OPEX for manufacturing: Our robust membrane technology requires less compressed air and boasts an extended lifespan, resulting in significant cost reductions compared to traditional gas purchasing.
  • Minimal footprint: The high productivity of our hollow fiber membranes minimizes the space required for installation, making it ideal for crowded factory floors or constrained agricultural sites.
  • Maximized versatility: Highly selective membranes ensure all your Nitrogen requirements—from food packaging to silo blanketing—are reliably met from a single installation.
  • Standards and safety: Our generators are designed to the highest quality and safety standards (ISO9001 and ASME U stamped) to secure your production lines.
  • Easy replacement: Membrane cartridges can be easily replaced by simply inserting them into the original pressure vessels, reducing maintenance costs. 

Air Liquide membranes have high productivity and selectivity. Our unique manufacturing process produces extremely small diameter fiber which transposes into smaller bundles than typical N2 membranes resulting in space and weight savings. Our membranes can operate up to 35 barg pressure and produce purities up to 99.9%. All our N2 membranes can reuse existing vessels to save cost and wastage.
