Stationary Nitrogen Generator

More and more manufacturers are realizing that relying on liquid nitrogen or high-pressure cylinders for nitrogen supply brings high costs, unstable availability, and frequent production delays caused by logistics disruptions.
The stationary nitrogen generator solves these pain points directly-it uses clean compressed air and the adsorption principle of carbon molecular sieves (CMS) to continuously separate nitrogen at the required purity, delivering truly "on-demand production, pay-as-you-use nitrogen."

Why Choose a Stationary Nitrogen Generator?

A reliable stationary nitrogen generator offers core value by freeing users from external gas supply dependency. Our systems are built on pressure swing adsorption (PSA) technology: when compressed air enters an adsorption tower filled with CMS, oxygen, moisture, and other impurities are preferentially adsorbed, while nitrogen passes through and is collected.
Dual towers work alternately-one adsorbs and produces nitrogen while the other regenerates and desorbs-ensuring continuous nitrogen output. The entire process consumes only compressed air, uses no chemical additives, and results in far lower operating costs than traditional nitrogen supply methods.

Key Performance Specifications

Operating Conditions & Energy Consumption

• Inlet Air Temperature: ≤40°C (refrigerated dryer recommended)
• Ambient Temperature Range: +5°C ~ +45°C
• Energy Consumption: ~0.02–0.05 kW per Nm³ of nitrogen (99.5% purity), compressor excluded. Overall plant operation saves ~50–70% in costs compared to liquid nitrogen vaporization.
• Maintenance Intervals: CMS service life 5–8 years (depends on inlet air quality); pneumatic valve cycle life ≥2 million cycles.

Technical Parameters (Typical 99.5% Purity Model)

• Model Options: S-PSA-50 / S-PSA-200 / S-PSA-800 (expandable)
• Adsorption Tower Material: Q345R / 304 stainless steel
• Control System: Siemens PLC + 7-inch touchscreen, supports remote data interface (Modbus TCP)
• Noise Level: ≤75 dB(A) at 1m distance
• Power Supply: 220V/380V, 50Hz, single-phase or three-phase optional

Industrial Applications (Partial List)

Suitable for industries with continuous nitrogen demand:

• Laser cutting and heat treatment shielding
• Chemical tank blanketing and purging

Certifications & Standards

Every stationary nitrogen generator is designed and manufactured in compliance with:

• GB/T 14794, TSG 21 (China Pressure Vessel Safety Technical Supervision Regulation)
• ISO 8573-1 (Compressed air quality classes)
• CE certification (for export models)
• ATEX configuration optional for explosive environments

All pressure vessels come with a Product Quality Certificate and third-party non-destructive testing reports.

Customization Capabilities

We don't sell fixed configurations. Instead, we adapt technically to your actual operating conditions:

• Purity on demand (95%, 99%, 99.9%, 99.99%, 99.999%)
• Flow rates from tens of liters per minute to thousands of Nm³/hour
• Required dew point and residual oil content (paired with high-efficiency purification systems)
• Skid-mounted, containerized, or weatherproof outdoor structures
• Automation levels: local control, DCS system integration, remote mobile monitoring
• Special materials: corrosion-resistant or low-temperature designs

Service Support

From selection to commissioning, we provide:

• On-site air source assessment: evaluate compressor and pre-treatment capacity first-avoid buying a system that doesn't work well on your line
• Production line integration survey: confirm piping routes, space occupation, and electrical interface requirements
• Installation & commissioning: our engineers on site until purity targets are met
• Operator training: at least two onsite personnel able to independently maintain the system
• Long-term spare parts supply: CMS, pneumatic valves, filter elements shipped within 3 working days
• After-sales response: 24h phone support + 48h on-site service (major industrial cities)
