Hongbo's Aluminum Alloy Modular Nitrogen Generator is a compact PSA nitrogen generation system designed for applications requiring a flexible and reliable on-site nitrogen supply.
The system uses carbon molecular sieve (CMS) as the adsorbent and aluminum alloy modular adsorption units to separate nitrogen from compressed air. Multiple modules can be configured according to required nitrogen flow and purity, providing a compact alternative to conventional nitrogen generation equipment.
With nitrogen purity configurations from 99.5% to 99.999%, the modular design is suitable for applications where installation space, system flexibility and nitrogen demand are important considerations.
An aluminum alloy modular nitrogen generator is a PSA-based nitrogen generation system that uses multiple compact aluminum alloy adsorption modules instead of conventional large adsorption vessels.
During operation, clean and dry compressed air enters the adsorption modules containing carbon molecular sieve. Oxygen and other adsorbed components are preferentially retained by the molecular sieve, while nitrogen passes through as the product gas.
The adsorption modules operate cyclically. While one group is producing nitrogen, another group is regenerated by pressure reduction. This continuous adsorption and regeneration cycle allows the system to provide a stable nitrogen supply for industrial processes.
Compact Equipment Structure
The aluminum alloy modular structure reduces the overall equipment footprint compared with conventional large adsorption tower configurations. This makes the system suitable for plants where installation space is limited.
Flexible Capacity Configuration
Nitrogen production capacity can be configured by combining different numbers of aluminum alloy modules. This allows the system to be matched more closely to the required nitrogen flow and purity.
Lightweight Modular Construction
The use of aluminum alloy modules provides a lightweight equipment structure while maintaining the mechanical requirements of the nitrogen generation process.
Easy Integration
The compact modular design can be integrated with air compressors, air treatment equipment, nitrogen buffer tanks and downstream nitrogen distribution systems.
Easier Maintenance
Individual modules and process components can be accessed and serviced without requiring the same equipment arrangement as a large conventional adsorption tower system.
How Does the Modular PSA Nitrogen Generator Work?
The system operates according to the pressure swing adsorption principle.
Step 1 — Compressed Air Preparation
Ambient air is compressed and treated through the air purification system to remove oil, water and other contaminants before entering the nitrogen generator.
Step 2 — Adsorption
Clean and dry compressed air enters the adsorption modules filled with carbon molecular sieve (CMS). Oxygen and other components are preferentially adsorbed by the molecular sieve, while nitrogen passes through the adsorption bed.
Step 3 — Nitrogen Collection
The separated nitrogen flows from the adsorption modules into the nitrogen buffer or surge tank before being supplied to the point of use.
Step 4 — Molecular Sieve Regeneration
When the molecular sieve approaches adsorption saturation, the corresponding module is depressurized. The adsorbed oxygen and other components are released, regenerating the molecular sieve.
Step 5 — Continuous Operation
The adsorption and regeneration cycles alternate automatically, allowing the system to continuously produce nitrogen.

Operating Condition
Adsorption pressure: ≥0.7 MPa
When the adsorption pressure is below 0.7 MPa, the nitrogen production capacity should be converted according to the actual operating condition.
Nitrogen Purity Options
The modular nitrogen generator can be configured for different nitrogen purity requirements:
- 99.5%
- 99.9%
- 99.95%
- 99.99%
- 99.995%
- 99.999%
The actual nitrogen flow decreases as the required purity increases. Therefore, the generator should be selected according to both nitrogen purity and required flow rate, rather than purity alone.
