PSA Oxygen Generator

• Installed with compressed air purifier and dryer to prolong the service life of molecular sieves.
• Adopt advanced pneumatic shut-off valve for fast start and stop without leakage, can meet frequent usage with high reliability and service life.
• Adopt automatic PLC controller with low annual operating failure.
• HMI (Human-Machine Interface): Features intelligent, one-button control with English subtitles and a touchscreen display for real-time monitoring of nitrogen flow, purity, equipment inlet/outlet pressure, and fault information. It also allows for online modification of equipment operating parameters.
• Selection of Renowned Brand Components: We offer optional components from leading brands, including Atlas Copco air compressors, Japan Iwatani molecular sieves, Siemens controllers, Airtac electronic components, Burkert (Germany) valves, and GEMÜ (Germany) valves.
• Remote Real-time Equipment Monitoring:
  1). Reserved RS485 communication ports (Modbus or Profibus communication protocols) or Industrial Ethernet communication ports are available to facilitate user integration of nitrogen generation equipment signals into their DCS (Distributed Control System) for real-time monitoring.
  2). We can directly provide industrial PCs, monitoring software, printers, etc., for seamless integration with the nitrogen generation equipment's control system for real-time monitoring.
  3). An Internet-based intelligent IoT (Internet of Things) system can also be provided for intelligent analysis and monitoring.
• Automatic Purging of Off-Spec Nitrogen:
  1). A product nitrogen sampling port is provided for the analyzer to sample and determine if the product nitrogen purity meets specifications.
  2). If purity is off-spec, the system automatically switches to the off-spec gas path to vent nitrogen.
  3). Once purity returns to specification, it automatically switches back to the qualified gas path to deliver product nitrogen to the consumption end.
• Unique Cylinder Compaction Technology: Automatic compensation for molecular sieve loosening ensures the molecular sieve remains consistently compacted. This effectively extends the lifespan of the molecular sieve and guarantees reliable, long-term operation of the equipment.
• Adsorption Tower Structure Technology: Further enhances molecular sieve utilization and improves equipment performance. The unique adsorption tower structure design effectively changes the speed and direction of internal airflow, reducing dead spaces within the tower. This further boosts molecular sieve utilization while preventing high-pressure airflow from impacting the molecular sieve, reducing pulverization. These factors contribute to extending molecular sieve lifespan, improving adsorption performance, and reducing energy consumption.

Our PSA oxygen generator can separate oxygen from compressed air utilizing zeolite molecular sieve (ZMS) when pressurized. As nitrogen has a higher diffusion rate in ZMS pores, the sieve will adsorb the nitrogen and moisture over oxygen, allowing the oxygen to pass as product gas at pressure. After de-pressurizing, the sieve releases adsorbed gases into the atmosphere, and the process can then be repeated.
