RICH’s membrane nitrogen generator is widely used in petroleum (tertiary oil recovery, natural gas recovery); Chemical industry (displacement, purging, shielding gas), metallurgy (carbonitriding, annealing, welding), electronics (shielding gas for electronic devices), transportation (flammable, explosive dangerous goods shielding gas); Coal (fire extinguishing, explosion-proof), medicine (nitrogen sealing, covering protective gas) and other fields.
Our membrane nitrogen generators adopt well-known brand membrane, high-end air purification and control systems, with the following features::
Saving on capital investment
Small in size
Low cost in maintenance
Rapid production with high purity
High stability and adaptability
| Nitrogen purity | 95%～99.5% |
| Nitrogen flow | 5～5000Nm³/h（20℃，101.325kPa） |
| Atmospheric pressure dew point | ≤-40℃ Customizable |
| Nitrogen pressure | 0.05~1.2 MpaCustomizable |
RICH “BGMN series” membrane separation nitrogen production equipment is divided into ten models according to nitrogen purity. They are: BGPN95、BGPN97、BGPN98、BGPN99、BGPN295、BGPN39、BGPN395、BGPN49、BGPN495、BGPN59、BGPN595.
You can choose according to the gas process requirements such as nitrogen purity, flow rate, etc.
-Automatic venting of unqualified nitrogen
-Reserved RS485 (Modbus or Profibus communication protocol) communication port or industrial Ethernet communication port
-Multi-tank inflation automatic switching, fully automatic start and stop
-In the event of equipment failure, power outage, or insufficient gas supply, the backup nitrogen will be automatically replenished and switched automatically
-One machine can produce more than two different purity nitrogen.
-Industrial computers, printers, intelligent IoT systems.
Membrane nitrogen generator is composed of air compressor, purification unit, nitrogen unit, nitrogen storage and other parts.

Since 1979, RICH has been a pioneer in gas generation technology. With thousands of successful installations worldwide, we bring decades of proven experience to your membrane nitrogen generator project—no matter your industry or application.
We don’t believe in one-size-fits-all. Whether you need a compact unit for electronics manufacturing or a robust system for offshore oil rigs, RICH engineers tailor each membrane nitrogen generator to your operational needs.
Our membrane nitrogen systems are designed for continuous, stable operation with minimal maintenance. The modular, oil-free design reduces downtime and ensures long service life—ideal for remote or demanding environments.
RICH membrane nitrogen generators use advanced hollow-fiber membrane technology to deliver nitrogen with lower energy consumption compared to traditional systems. You get high purity with lower operating costs.
Need a skid-mounted or containerized nitrogen solution? We offer plug-and-play systems with fast delivery and quick installation—perfect for projects with tight timelines.
From design and manufacturing to on-site installation, commissioning, after-sales support, and equipment leasing, RICH is your one-stop partner for nitrogen generation. Our global service network ensures you're supported—wherever your plant is.
