Oxygen Enrichment Facility, rated to 27–30% O2 at 5000 m.

System purpose & operational context

At elevations around 5000 m — where barometric pressure is approximately half that at sea level — the partial pressure of oxygen drops enough to induce hypobaric hypoxia, leading to acute mountain sickness, impaired cognition, and cardiovascular strain. The Neometrix Oxygen Enrichment Facility (OEF) addresses these challenges by raising indoor oxygen concentration from 21% (ambient) to 27–30%, simulating a much lower equivalent altitude. Deployed in research outposts, military encampments, medical tents, and acclimatization shelters, the OEF ensures personnel maintain optimal physiological function during prolonged high-altitude exposure.

Core technology: PSA oxygen generation

• Dual-column PSA towers: two parallel adsorption columns packed with lithium-exchanged zeolite alternately adsorb nitrogen and regenerate, providing a continuous oxygen stream.
• Molecular sieve design: high-performance sieves deliver >93% purity oxygen in the 80 LPM model, while 40% purity in the 130 LPM and 230 LPM models is blended into room air for energy efficiency.

Modular variants & performance metrics

Automated environmental control

• PLC-based closed-loop logic: starts concentrators when O2 <27% and stops at 35%; triggers CO2 exhaust fans for 60 seconds when CO2 >3000 ppm.
• User-configurable setpoints: operators can adjust thresholds, schedules, and view historical logs via HMI.
• Continuous real-time monitoring: O2 and CO2 levels are updated every 2 seconds for responsive control.
• Failsafe logic integration: in case of sensor failure, the system enters a predefined safe mode with alert triggers.
• Data logging: 24/7 environmental data archiving with USB export or cloud sync.
• Multi-zone control (optional): manage oxygen levels across different rooms independently.

Distribution & patient interfaces

• High-pressure oxygen piping: delivers gas at 4 bar through copper mains and PU tubing to wall nozzles mounted at 1 m height for uniform mixing.
• Nasal cannula outlets: dedicated ports for direct therapy, especially in the 80 LPM model.
• Anti-backflow design: check valves on all outlets to prevent contamination.
• Custom nozzle placement: can be configured for bunk beds or central flow diffusion.
• Optional humidifiers: attachments available for comfort during continuous oxygen therapy.
• Color-coded piping & quick couplers: for safe and easy operation.

Safety, alarms & redundancy

• Overpressure relief valves (5 bar)
• Emergency stop buttons
• Redundant sensors & self-diagnostics
• MCBs & surge protection
• Alarm prioritization (Critical/Warning/Advisory)
• Automated purge cycle during emergency shutdown
• Compatibility with fire detection systems
• Low voltage disconnection feature

Installation & commissioning

• Skid-mounted with caster wheels for easy transport
