Intermittent gas usage and small enterprises: +10%～15%
24-hour continuous production, assembly lines and non-stop working conditions: +20%～30%
Severe gas consumption fluctuation and high instantaneous gas consumption peak: Increase the margin or install a nitrogen storage tank

Step 2: Select nitrogen purity by industry

Industry of Application | Required Purity

Food packaging, beverages, anticorrosion, fire protection, purging | 95%～99.0%

Chemical replacement, warehouse moisture-proofing, pipeline purging, hardware rust prevention | 99.0%～99.9%

Heat treatment, powder metallurgy, die casting, injection molding, rubber, cables | 99.9%

Laser cutting, welding protection, pharmaceuticals, lithium batteries, glass | 99.99%

Electronic semiconductors, laboratories, special materials, precision welding | 99.999%

Principle: Sufficient is enough. With each upgrade in purity grade, equipment costs and power consumption rise significantly.

Step 3: Determine Working Pressure

Conventional Low-Pressure Nitrogen Supply

Standard outlet pressure of nitrogen generator: 0.6～0.8 MPa

Application: Packaging, purging, dust removal, conveying and general protection

Medium and High-Pressure Nitrogen Supply

Additional nitrogen booster required

1.0～1.6MPa: Chemical industry and container pressure testing

2.0～3.0MPa: Rubber vulcanization and high-pressure sealing

Above 3.0MPa: Military industry and special tests

Step 4: Select the nitrogen generation principle (three major types)

PSA Pressure Swing Adsorption Nitrogen Generation (the most commonly used and preferred option in industry)
Flow rate: Full coverage from 3 to 3000Nm³/h Purity: 95% ~ 99.999%
Advantages: Low investment, ready for immediate use after startup, simple operation and maintenance, stable 24-hour operation Application: General scenarios for 90% of factories
Membrane Separation Nitrogen Generation
Low upper limit of purity: maximum 99.5%Advantages: Compact size, no vulnerable partsApplication: Low-demand scenarios, small gas volume, outdoor use and simple purging
Cryogenic Air Separation Nitrogen Generation
Ultra-large flow rate and ultra-high purity
Application: Large chemical plants, coal chemical industry and scenarios with gas consumption of tens of thousands of cubic meters; not recommended for small and micro enterprises
