The membrane nitrogen generator employs 'membrane separation technology,' achieving nitrogen and oxygen separation based on the differences in the permeation rates of different gas molecules within the membrane material:

The core component is a 'hollow fiber membrane,' made of high-molecular polymers (such as polyimide or polysulfone), which has a higher permeation rate for oxygen, water vapor, and CO₂ than for nitrogen.

When compressed air enters the membrane module, 'faster gases' such as oxygen permeate through the membrane wall and are discharged, while nitrogen is enriched and output from the center of the membrane.

No adsorbent required: No molecular sieve regeneration step, simple structure.

Instant response: Nitrogen can be produced within 1 minute of startup, suitable for intermittent gas supply needs.

1. Technical Features

Features:

Purity range: 95%~99.5% (affected by intake conditions)

Start-up speed: Instant nitrogen production (<1 minute)

Low energy consumption (even lower energy consumption when there is no compression requirement)

Maintenance cost: No moving parts, minimal maintenance (only periodic replacement of membrane modules required)

Adaptability & vibration resistant, suitable for mobile equipment (such as oilfield vehicle systems)

Advantages:

It has a compact structure and occupies a small area.

Simple to operate and highly automated.

Limitations:

The purity limit is lower than that of PSA technology (it is difficult to reach 99.999%).

Membrane modules have a limited lifespan (usually need to be replaced every 3-5 years).

2. Application Scenarios

Oil and gas, food industry, chemical and pharmaceutical industry, electronics manufacturing, nitrogen tire filling, fire protection systems (such as nitrogen fire suppression in data centers), and others.

3. Equipment Composition

Core components, auxiliary systems, air compressor, pretreatment filter, and intelligent control system.

Membrane nitrogen generators are characterized by 'rapid start-up, low maintenance, and compact design,' making them suitable for scenarios requiring small to medium flow rates and medium purity.
