Membrane Separation Nitrogen Generator: On-Demand Purity, Unmatched Convenience

Generate High-Purity Nitrogen Anywhere, Anytime
Membrane separation nitrogen generators leverage cutting-edge polymer fiber technology to efficiently extract high-purity nitrogen (N₂) directly from compressed air. By exploiting the differential permeation rates of oxygen and nitrogen molecules through hollow fiber membranes, these systems deliver a continuous, reliable stream of dry nitrogen – eliminating logistical hassles and costly cylinder rentals. Ideal for industries requiring flexible, on-site nitrogen solutions without chemical consumables.

Key Features & Advantages

1. Unrivaled Mobility & Rapid Deployment:

   • Compact, Skid-Mounted Design: Integrated systems (compressor, dryer, filters, membrane modules) are pre-assembled on robust frames.
   • Plug-and-Play Operation: Simply connect to a power source and compressed air inlet (or use integrated compressor) for near-instantaneous nitrogen production (<5 minutes typical startup).
   • Effortless Relocation: Forklift pockets and optimized weight distribution facilitate movement between sites or production lines.

2. Intelligent Operation & Low Maintenance:

   • Fully Automated Control: Advanced PLC systems continuously monitor flow, pressure, and purity. Touchscreen interfaces simplify adjustment and provide real-time diagnostics.
   • Minimal Routine Care: Membrane modules require no regeneration chemicals or moving parts. Maintenance primarily involves scheduled air filter changes.
   • Energy Optimized: Operates efficiently at standard compressed air pressures (typically 7-10 bar / 100-150 psi), consuming far less energy than cryogenic plants.

3. Pure, Dry Nitrogen Output:

   • Adjustable Purity: Typically delivers 95% to 99.9% nitrogen purity on-demand, adjustable based on application needs.
   • Integrated Air Prep: Built-in refrigeration dryers and multi-stage filtration (particulate, coalescing, activated carbon) ensure feed air is clean, dry (<-40°C dew point), and oil-free, protecting membranes and guaranteeing gas quality.
   • Consistent Supply: Nitrogen buffer tank ensures stable pressure and flow, compensating for demand fluctuations.

4. Sustainable & Cost-Effective:

   • Zero Chemical Waste: Separation process is purely physical, producing no hazardous byproducts or spent adsorbents.
   • Pay-as-You-Produce: Dramatically reduces costs compared to bottled or liquid nitrogen deliveries, especially for continuous use. Rapid ROI common.
   • Reduced Carbon Footprint: Eliminates transportation emissions associated with delivered nitrogen.

Typical Technical Specifications

(Note: Exact specifications depend on model, configuration (with/without integrated compressor), and desired purity/flow. Custom solutions available.)

Frequently Asked Questions (FAQ)

1. What purity levels can realistically be achieved?
Membrane generators excel at producing nitrogen in the 95% - 99.5% purity range. While 99.9% is achievable, it significantly reduces flow rate. For >99.5% consistently, Pressure Swing Adsorption (PSA) generators might be more suitable. Membrane is optimal for applications requiring constant flow at moderate high purity.

2. How long do the membrane modules last?
With proper feed air quality (critical!), membrane life typically exceeds 8-10 years. Key factors: maintaining effective oil removal (activated carbon filter), particulate filtration, and consistent dew point control. Our integrated prep ensures optimal conditions.

3. Can it really start and stop instantly?
Yes! Unlike PSA systems requiring cycle times, membrane generators produce nitrogen almost immediately upon start-up (within minutes to reach stable purity). They can be stopped and restarted instantly without process penalties or wasted gas.

4. What maintenance is required?
Maintenance is minimal:
* Regular replacement of inlet air filters (pre-filter, coalescing, activated carbon - schedule depends on air quality).
* Occasional checking of system pressures/monitors.
* Membrane modules themselves require no routine maintenance.

5. Are these generators energy efficient?
Absolutely. Membrane systems operate at the pressure of your compressed air line (~7-10 bar). They consume significantly less energy than cryogenic plants and generally have lower specific power consumption than comparable PSA systems for purities up to ~99.5%. The energy cost is primarily the compression of the feed air.
