Industrial Nitrogen Generators & Nitrogen Generation Systems
Griffin Air Systems supplies industrial nitrogen generators and nitrogen generation systems for businesses across the UK. Our on-site nitrogen solutions allow businesses to generate nitrogen from compressed air, providing a reliable nitrogen supply tailored to the required flow rate, pressure and purity.
From PSA nitrogen generators to bespoke skid and containerised solutions, we can help you select, install and maintain the right system for your application.
Why Choose an On-Site Nitrogen Generator?
For businesses with a regular or high-volume nitrogen requirement, generating nitrogen on-site can provide greater control over supply and reduce reliance on delivered gas cylinders or bulk nitrogen. An appropriately specified nitrogen gas generator can provide a continuous supply of nitrogen when and where it is needed, helping businesses improve operational reliability and manage their ongoing gas requirements.

How Does a Nitrogen Gas Generator Work?
An industrial nitrogen generator separates nitrogen from the other gases present in atmospheric air. The nitrogen is then collected and supplied for use within the business.
One of the most common technologies used for industrial nitrogen generation is Pressure Swing Adsorption (PSA).
PSA Nitrogen Generation Process
PSA nitrogen generators use molecular sieve technology to separate nitrogen from compressed air through a multi-step process:
The PSA Process Steps:
- Compressed air enters the nitrogen generator after being suitably treated and filtered.
- The compressed air passes through a molecular sieve, which selectively adsorbs oxygen and other unwanted gases.
- Nitrogen passes through the sieve and is collected as the product gas.
- The adsorption vessel regenerates by reducing pressure and releasing the adsorbed gases.
- Multiple sieve beds alternate between adsorption and regeneration to provide a continuous nitrogen supply.
N-GEN PSA Nitrogen Generators
Our N-GEN nitrogen generators use Pressure Swing Adsorption (PSA) technology to produce nitrogen from compressed, purified air.
The system uses alternating adsorption vessels to provide continuous nitrogen production. As one vessel produces nitrogen, the other regenerates before the process switches between the two.
This makes PSA technology suitable for industrial applications where a dependable supply of nitrogen is required.
The appropriate specification will depend on your required nitrogen purity, flow rate, pressure and application.
N-GEN Nitrogen Generator Specifications
| Specification | N-GEN Range |
|---|---|
| Operating pressure | 6–10 bar |
| Operating temperature | 5–50°C |
| Ambient air temperature | Up to 40°C |
| Atmospheric dew point | < -45°C |
| Capacity | 0.83–766.8 Nm³/h |
| Nitrogen purity | Up to 99.999% |
Nitrogen Generator Standard Equipment
A nitrogen generation system requires a range of supporting components to ensure reliable operation and consistent nitrogen production.
Standard N-GEN equipment includes:
- External feed air filters
- Carbon steel adsorber vessels
- Long-life pneumatic and solenoid valves
- Zinc-plated carbon steel internal piping and fittings
- Product pressure transmitters
- Nitrogen and airflow regulation
- Pressure regulator
- SIEMENS PLC control system
- WebControl
The quality and condition of the compressed air entering a nitrogen generator can have an important role in system performance. Griffin Air Systems also supplies compressed air filtration equipment, helping businesses ensure their compressed air is appropriately treated for its intended application.
Optional Nitrogen Generator Equipment
Additional equipment can be incorporated into a nitrogen generation system where required. Available options include:
- Oxygen analyser
- Electronic product flow meter
- Feed air/product moisture analyser
- Feed air/product temperature transmitters
- Nitrogen sterile filters
- Nitrogen booster
- Nitrogen cylinder filling system
- Touchscreen interface
- Serial communications
Our team can advise on the most appropriate equipment for your application, including monitoring and control requirements.
Industrial Nitrogen Generator Applications
Industrial nitrogen generators are used across a wide range of manufacturing, processing and engineering applications where an inert atmosphere, controlled environment or high-purity gas supply is required.
Laser Cutting
Chemical Processing
Gas-Assisted Injection Moulding
Food Processing & Packaging
Inerting Flammable Liquids
UV Curing
Metal Heat Treatment
Electronics & PCB Manufacturing
Dust Explosion Prevention
Bespoke Nitrogen Generator Skids & Containers
Not every business has the same space, production requirements or installation environment. Griffin Air Systems can provide bespoke nitrogen generator skids and containerised solutions designed around individual project requirements.
Our industrial engineering capabilities allow compressed air and gas treatment equipment to be integrated into packaged systems, helping businesses make effective use of their available space while simplifying installation.
Our equipment range includes cyclone separators, compressed air filters, air dryers, condensate drains, gas generators and pressure vessels.
Projects can be designed around applicable specifications and design codes, including PED, ASME, DNV, ABS, NR13 and AS1210, depending on project requirements.
Installation, Servicing & Support
Choosing the right generator is only part of creating a dependable nitrogen supply system. Correct installation, system configuration and ongoing maintenance are also important for maintaining reliable performance.
Griffin Air Systems provides compressed air engineering and equipment support for businesses across the UK. Our engineers can service and maintain nitrogen generators alongside other compressed air equipment.
For businesses looking to integrate nitrogen generation with their existing compressed air infrastructure, we can also supply associated equipment including air compressors, air dryers and filtration systems.
Nitrogen Generator vs Delivered Nitrogen Gas
For businesses with ongoing nitrogen requirements, an on-site nitrogen generator can provide an alternative to relying solely on delivered nitrogen.
The most suitable option will depend on factors such as:
- Required nitrogen purity
- Nitrogen consumption and flow rate
- Operating pressure
- Hours of operation
- Available compressed air capacity
- Available installation space
- Existing nitrogen storage and supply arrangements
- Capital and operating costs
- Application requirements
There is no single nitrogen generation solution suitable for every business. The correct system should be sized and specified around actual nitrogen demand and application requirements.
