What are Membrane Nitrogen Generators?
Membrane nitrogen generators produce nitrogen rapidly once started. Adopting hollow fiber membrane separation technology, they have no moving adsorption parts. With compact structure and low maintenance demand, they are well suited for working conditions requiring medium and low nitrogen purity.
We offer integrated skid-mounted and modular split series to match different nitrogen flow demands.
Key components include hollow fiber membrane modules, filters, pressure regulating valves and PLC control system. All units pass performance testing before delivery.
Besides nitrogen generator main bodies, we also supply matching auxiliary equipment, and our team provides professional scheme design and technical consultancy for nitrogen supply projects.
How to Choose the Right Membrane Nitrogen Generators
When picking the right membrane nitrogen generator, first confirm your required nitrogen purity, flow rate and working pressure. Membrane technology is more suitable for medium and low nitrogen purity scenarios, which is a key distinction from PSA nitrogen generators.
Assess your on-site conditions and structural layout. You can choose skid-mounted integrated units for simple installation or modular split machines if you have limited space or special maintenance requirements.
Check the quality of compressed air inlet. Oil, dust and moisture will damage hollow fiber membrane modules, so matched filters and dryers are essential to protect the membrane core.
We customize nitrogen systems based on site conditions and provide scheme design, installation, commissioning and after-sales service for domestic and overseas clients.
FAQ
Q1: What is the working principle of membrane nitrogen generator?
A: It uses hollow fiber membrane separation technology. Different gas molecules pass through the polymer membrane at different speeds to separate nitrogen from compressed air.
Q2: What parameters should be confirmed before selecting a membrane nitrogen generator?
A: Confirm nitrogen purity, gas flow and working pressure. Membrane nitrogen generators are mainly for medium and low purity nitrogen applications.
Q3: What industries are membrane nitrogen generators suitable for?
A: Widely used in food packaging, marine tank inerting, oil & gas pipeline purging, tire nitrogen filling, laboratory gas supply and material anti-oxidation protection.
Q4: What are the advantages of membrane nitrogen generators compared with PSA nitrogen generators?
A: Fast startup, compact structure, no moving adsorption parts and low maintenance. It runs continuously with fewer wearing components.
Q5: What structural types do you supply?
A: We provide skid-mounted integrated units and modular split machines for different site layout requirements.
Q6: What air quality requirements does the membrane nitrogen generator have for inlet compressed air?
A: The inlet air must be dry and clean. Oil, dust and moisture will damage hollow fiber membrane modules and shorten service life.
Q7: Can the nitrogen output purity of membrane nitrogen generator be adjusted?
A: Nitrogen purity can be adjusted within a certain range by changing air pressure and flow rate, but it cannot reach ultra-high purity.
Q8: What services do you offer for membrane nitrogen projects?
A: We provide site survey, scheme customization, installation, commissioning, technical training and long-term after-sales support.
