  1. Operating Nitrox Membrane Systems Presented by Nuvair Operating Nitrox Systems

  2. Membrane systems produce nitrox efficiently • Compressed air flows through the membrane • Nitrogen rich gas is expelled • Oxygen rich gas is produced Operating Nitrox Systems

  3. Components of the membrane system Nitrogen release Permeate O2 Rich Gas Membrane Air Filter Mixing Tube Intake hose Operating Nitrox Systems

  4. Components of the membrane system Analyzer Regulator Heater Filters Heater Thermostat Operating Nitrox Systems

  5. System Specifications • Membrane temperature: 110 degrees F or 43 degrees C • Operating pressure: 80-170 p.s.i., 6-12 bar • Max input pressure: 300 p.s.i. or 21 bar • Air supply quality: LP Grade D, HP Grade E • Nitrox Range: 24% - 40% Operating Nitrox Systems

  6. The membrane is incorporated in these systems For dive operators who own HP compressors For dive operators who want a complete nitrox solution Operating Nitrox Systems

  7. Rotary Screw System Operation • System is for dive operators who already own HP compressor Operating Nitrox Systems

  8. Rotary Screw System Components Inline Permeate O2 Analyzer On/Off Switch Membrane Control Panel Nitrox out To HP Power Switch Drier on/off switch Operating Nitrox Systems

  9. Rotary Screw System Components Adjust O2 % HP Intake Operation Gauge Nitrox out To HP Operating Nitrox Systems

  10. Rotary System Rear Components Waste air Heater Thermostat Control Pressure switch Operating Nitrox Systems

  11. Easy operation • Always read the manual first! • Steps vary depending on installation • Check oil level & filters first • Turn on drier Operating Nitrox Systems

  12. Calibrate the fill O2 analyzer Operating Nitrox Systems

  13. Follow the steps in the manual • Turn on HP compressor • Adjust fill whip allowing air to escape • Calibrate permeate O2 analyzer • Turn on LP compressor Operating Nitrox Systems

  14. Follow all safety precautions • Adjust input pressure to over 80 p.s.i. (5.5 bar) • Verify thermostat operation • Increase or decrease pressure to set final O2% Operating Nitrox Systems

  15. Final adjustments • Fill O2 analyzer should read same as inline O2 analyzer • You are ready to pump nitrox! Operating Nitrox Systems

  16. Always test the nitrox in the cylinder with an independent analyzer! • Have the customer analyze the gas and sign for it Operating Nitrox Systems

  17. Components of the Voyager (nitrox in a box!) Fill pressure gauge Fill O2 Analyzer Permeate O2 Analyzer Dial-A-Pressure Control HP Filter Cannister LP Filters Operating Nitrox Systems

  18. Additional Voyager components… Feed air control LP Gauges HP Controls LP Oil Level Temperature Gauges Heater Thermostat HP Oil Level Operating Nitrox Systems

  19. Using the Voyager • Always read the manual first! • Check oil level & filters • Check LP feed valve is off • Start HP compressor Operating Nitrox Systems

  20. Using the Voyager • Open one fill whip - adjust to hold 1500 p.s.i. (103 bar) • Drain condensate • Calibrate analyzers Operating Nitrox Systems

  21. Operation is simple! • Adjust regulator initially for low pressure • Turn on LP feed air valve • Increase regulator pressure to 80-160 p.s.i. (5.5-11 bar) Operating Nitrox Systems

  22. Operation is simple! • Wait for O2% to stabilize on permeate analyzer • Adjust regulated input pressure • Wait for correct nitrox % on the fill O2 analyzer • When O2% is correct, attach whip & fill tank! Operating Nitrox Systems

  23. Always test the nitrox in the cylinder with an independent analyzer! • Have the customer analyze the gas and sign for it Operating Nitrox Systems

  24. Operation of membrane systems is easy! • Membrane systems provide accurate nitrox mixtures. • Membrane systems require the least amount of training. • Membrane systems allow you to fill nitrox tanks at same rate as air tanks. Operating Nitrox Systems
