Nitrogen Generators
On-site nitrogen generation for controlled and cost-effective supply.
On-site nitrogen generators provide a reliable alternative to delivered gas cylinders or bulk liquid supply. By producing nitrogen directly from compressed air, systems reduce dependency on external deliveries while offering improved cost control and consistent gas purity.
Why Generate Nitrogen On-Site?
Traditional nitrogen supply methods rely on deliveries and storage infrastructure. On-site generation provides greater control, predictable costs and improved operational flexibility.
- Reduced reliance on gas deliveries
- Lower long-term operating costs
- Continuous on-demand supply
- Adjustable purity levels
- Improved safety (no high-pressure cylinder storage)
- Scalable system design
Types of Nitrogen Generators
PSA Nitrogen Generators
Pressure Swing Adsorption (PSA) systems separate nitrogen from compressed air using carbon molecular sieve technology. Suitable for higher purity requirements across industrial applications.
Membrane Nitrogen Generators
Membrane systems separate nitrogen through selective permeation. Compact and reliable, they are suited to moderate purity requirements and continuous operation.
Typical Applications
Food Packaging
Modified atmosphere packaging (MAP) processes.
Laser Cutting
Assist gas for fibre and CO₂ laser systems.
Pharmaceutical Production
Controlled inert environments.
Chemical Processing
Oxidation prevention and inerting.
Electronics Manufacturing
Controlled atmosphere protection.
Oil & Gas Applications
Purging and inerting operations.
System Specification & Integration
Nitrogen generation systems must be correctly sized and integrated with compressed air supply and storage to ensure stable purity and flow.
- Required nitrogen purity (%)
- Flow rate (Nm³/hr)
- Operating pressure
- Compressed air quality
- Buffer storage requirements
- Future expansion capacity
