Membrane type

Airpack offers a complete range of membrane type nitrogen generators. Based on the principal of hollow-fiber membrane techniques our nitrogen generators are capable of producing up to 99,9% nitrogen purity on-site by using compressed air only. 

No need for expensive, bottled nitrogen deliveries anymore. With Airpack's membrane nitrogen generator packages you will have a reliable and easy source for your everyday safety gas requirement. 

Membrane nitrogen generator

Airpack nitrogen generator packages come completely assembled and shop tested. All interconnecting piping, wiring and control systems are included. Only local hook-up is required.

Advantages of Airpack membrane nitrogen generator packages

- Simple design and easy control 
- Desired purity within minutes
- Up to 80% lower investment compares to PSA systems 
- Compact design, small footprint and reduced power consumption

Airpack nitrogen generator packages are featured with the latest models in hollow fiber membrane techniques. 

By pushing pressurized air through the membranes the nitrogen and oxygen are separated into two different streams. One stream of nitrogen at desired purity and a (waste) stream of enriched air. At the outlet of the membrane the purity is checked by an oxygen analysis system and either send downstream to nitrogen consumer or vented to safe area if oxygen content is too high. 

Airpack nitrogen generator packages come complete assembled and shop tested. All interconnecting piping, heaters, membrane houses and control systems are included.

As our membranes require just minutes to reach the desired purity the start-up time of our nitrogen packages is remarkably shorter compared to PSA systems, which require days to reach their purity level. Additionally Airpack nitrogen generators require no large suction and receiver vessels because of the continued supply stream of nitrogen.

Please find below our nitrogen generator range rang as well as all available options and special features. 

Cooling and heating
When necessary the feed air stream will be cooled or heated to reach the optimal membrane inlet temperature. Heating or cooling systems are included in the nitrogen generator package. 

Control
Nitrogen generator control will be by custom programmed PLC. Purity will be constantly monitored by oxygen analyzing system. 

Membrane housing
Our in-house designed membrane housing can be offered in stainless steel upon request for offshore or refinery applications.

Optional
Airpack nitrogen generators can be featured with the following optional items, as per your request.

  • Stainless steel components like process piping, control panels, coolers, heaters, instruments and separators (e.g. offshore or refinery applications)
  • ATEX explosion proof, suitable for operation in Zone 1 or Zone 2 environment
  • Control by redundant and/or SIL (Safety Integrity Level) certified PLC 
  • Control panel with HMI (human machine interface) for operation via keypad or touch screen
  • Winterization enclosure, for extreme low temperatures down to -50ºC
  • Tropicalization for extreme high ambient temperatures up to 60ºC
