A Fully Automatic PSA Nitrogen Generator with PLC Control

A Fully Automatic PSA Nitrogen Generator with PLC Control is an industrial system designed to produce high-purity nitrogen gas on-site using Pressure Swing Adsorption (PSA) technology and automated monitoring/control through a PLC (Programmable Logic Controller).

• Fully Automatic Operation
  • Automatic start/stop
  • Auto pressure regulation
  • Continuous nitrogen production
  • Minimal operator intervention
• PLC Control System
  • Touchscreen HMI interface
  • Real-time monitoring of purity, pressure, and flow
  • Alarm and fault diagnostics
  • Remote monitoring capability (optional)
• High Nitrogen Purity
  • Typically: 95% to 99.999%
  • Adjustable depending on application
• Energy Efficient
  • Low operating cost compared to bottled nitrogen
  • Optimized air consumption
• Compact & Modular Design
  • Easy installation
  • Expandable capacity

1. Air Compressor
2. Air Dryer & Filters
3. PSA Nitrogen Generator Towers
4. Carbon Molecular Sieve (CMS)
5. Nitrogen Buffer Tank
6. PLC Control Panel
7. Oxygen Analyzer

Compressed air enters the PSA towers filled with carbon molecular sieve. Oxygen molecules are adsorbed while nitrogen passes through as the product gas. The towers alternate automatically under PLC control to ensure uninterrupted nitrogen supply.
