Modular PSA Oxygen Plant
LDH Gas Systems Company Limited introduces the Modular PSA Oxygen Plant -a versatile, cost-effective solution for industries requiring 90–93% purity oxygen. Leveraging decades of expertise in cryogenic systems, our skid-mounted plants deliver industrial-grade oxygen precisely where you need it.
How It Works: Efficient Air Separation
- Our PSA technology uses zeolite molecular sieves to adsorb nitrogen from compressed air through pressure cycling:
- Adsorption : Compressed air enters vessels, where molecular sieves trap nitrogen molecules.
- Desorption : Reduced pressure releases nitrogen, regenerating sieves.
- Continuous Output: Dual vessels alternate cycles for uninterrupted O₂ flow.
Universal Applications
- Wastewater Treatment: Ozonation support for sludge reduction.
- Medical Facilities: Backup oxygen supply for hospitals/clinics (meets ISO 8573-1 standards).
- Metallurgy: Combustion enhancement in furnaces.
- Aquaculture: Oxygen enrichment for fish farming.
Core Advantages
● Plug-and-Play Modularity:
Pre-assembled skids (air compressor, dryer, buffer tanks, control system).
Quick installation ≤4 hours.
Energy-Smart: 30% lower power consumption vs. conventional systems.
● Smart Monitoring:
LCD touchscreens for real-time purity/flow tracking.
Optional Wi-Ctrl remote diagnostics and OTA updates.

Why LDH Stands Out
- Certified Excellence: ISO 9001, CE, and China Compulsory Certification (CCC).
- Global Installations: 50+ countries (e.g., Peru, Iraq, Philippines).
- Custom Engineering: Solutions for high altitudes (≤4,000m), extreme climates (-20°C to 50°C), and space constraints.
- Proven Reliability: Molecular sieve lifespan >10 years with IPQC safeguards.
End-to-End Support
- Warranty: 1-year comprehensive coverage + lifetime maintenance.
- 24/7 Response: On-site support ≤24 hrs (global service centers).
- Training: Operator certification and troubleshooting workshops.
- Spare Parts: Genuine components with 48-hr global dispatch.
FAQ: Quick Answers
Q: How fast does it produce oxygen?
A: Generates compliant O₂ within 20 minutes of startup.
Q: Can it integrate with existing air compressors?
A: Yes! Accepts ISO 8573-1 Class 1-4-1 air (7.5 bar inlet pressure).
Q: What remote features are available?
A: Real-time alerts, historical data logging, and remote start/stop via app.
Q: Is containerization possible?
A: Absolutely. Weatherproof designs for harsh environments.
