PSA Nitrogen Generator – High-Purity On-Site Nitrogen Gas System for Industrial Use

How It Works
Using compressed air as feedstock, the system leverages the differing adsorption rates of oxygen and nitrogen on carbon molecular sieves. Through a cyclic process of pressure adsorption and decompression desorption, nitrogen is efficiently separated directly from the air.

Key Advantages

• Low Operating Cost – Powered mainly by electricity, costs are significantly lower than purchasing liquid or bottled nitrogen.

• Easy to Use – Nitrogen is generated on-site and used immediately, eliminating the need for cylinder or liquid tank management.

• Flexible Purity – Purity can be stably adjusted from 95% to 99.999% by modifying process parameters.

• Fully Automated – PLC-controlled system ensures automatic operation with minimal manual intervention.

• Safe & Reliable – No high-pressure vessels or cryogenic media, reducing safety risks.

Main Application Industries

• Electronics– Prevents oxidation in reflow and wave soldering processes.

• Food & Pharmaceutical–Used for nitrogen sealing and inert gas protection during packaging and transport.

• Chemical–Provides nitrogen sealing for storage tanks and pipeline purging.

• Metal Heat Treatment–Enhances product quality in bright annealing, quenching, and carburizing.

• Coal & Mining –Supports fire prevention, extinguishing, and gas dilution.
