1 Operating Nitrox Systems 11 Presented by Nuvair

2 Operating Nitrox Systems2 Membrane systems produce nitrox efficiently Compressed air flows through the membrane Nitrogen rich gas is expelled Oxygen rich gas is produced Compressed air flows through the membrane Nitrogen rich gas is expelled Oxygen rich gas is produced

3 Operating Nitrox Systems3 Components of the membrane system Intake hose Membrane Air Filter Mixing Tube Permeate O2 Rich Gas Nitrogen release

4 Operating Nitrox Systems4 Components of the membrane system Heater Analyzer Filters Regulator Heater Thermostat

5 Operating Nitrox Systems5 System Specifications Membrane temperature: 110 degrees F or 43 degrees C Operating pressure: 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% Membrane temperature: 110 degrees F or 43 degrees C Operating pressure: 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%

6 Operating Nitrox Systems6 The membrane is incorporated in these systems For dive operators who own HP compressors For dive operators who want a complete nitrox solution

7 Operating Nitrox Systems7 Rotary Screw System Operation System is for dive operators who already own HP compressor

8 Operating Nitrox Systems8 Rotary Screw System Components Control Panel Power Switch Inline Permeate O2 Analyzer Membrane Nitrox out To HP On/Off Switch Drier on/off switch

9 Operating Nitrox Systems9 Rotary Screw System Components Operation Gauge Adjust O2 % HP Intake Nitrox out To HP

10 Operating Nitrox Systems10 Rotary System Rear Components Heater Thermostat Control Pressure switch Waste air

11 Operating Nitrox Systems11 Easy operation Always read the manual first! Steps vary depending on installation Check oil level & filters first Turn on drier Always read the manual first! Steps vary depending on installation Check oil level & filters first Turn on drier

12 Operating Nitrox Systems12 Calibrate the fill O2 analyzer

13 Operating Nitrox Systems13 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 Turn on HP compressor Adjust fill whip allowing air to escape Calibrate permeate O2 analyzer Turn on LP compressor

14 Operating Nitrox Systems14 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% Adjust input pressure to over 80 p.s.i. (5.5 bar) Verify thermostat operation Increase or decrease pressure to set final O2%

15 Operating Nitrox Systems15 Final adjustments Fill O2 analyzer should read same as inline O2 analyzer You are ready to pump nitrox! Fill O2 analyzer should read same as inline O2 analyzer You are ready to pump nitrox!

16 Operating Nitrox Systems16 Always test the nitrox in the cylinder with an independent analyzer! Have the customer analyze the gas and sign for it

17 Operating Nitrox Systems17 Components of the Voyager (nitrox in a box!) Fill O2 Analyzer HP Filter Cannister Fill pressure gauge Permeate O2 Analyzer Dial-A-Pressure Control LP Filters

18 Operating Nitrox Systems18 Additional Voyager components… HP Controls LP Oil Level HP Oil Level Feed air control LP Gauges Temperature Gauges Heater Thermostat

19 Operating Nitrox Systems19 Using the Voyager Always read the manual first! Check oil level & filters Check LP feed valve is off Start HP compressor Always read the manual first! Check oil level & filters Check LP feed valve is off Start HP compressor

20 Operating Nitrox Systems20 Using the Voyager Open one fill whip - adjust to hold 1500 p.s.i. (103 bar) Drain condensate Calibrate analyzers Open one fill whip - adjust to hold 1500 p.s.i. (103 bar) Drain condensate Calibrate analyzers

21 Operating Nitrox Systems21 Operation is simple! Adjust regulator initially for low pressure Turn on LP feed air valve Increase regulator pressure to p.s.i. ( bar) Adjust regulator initially for low pressure Turn on LP feed air valve Increase regulator pressure to p.s.i. ( bar)

22 Operating Nitrox Systems22 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! 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!

23 Operating Nitrox Systems23 Always test the nitrox in the cylinder with an independent analyzer! Have the customer analyze the gas and sign for it

24 Operating Nitrox Systems24 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. Membrane systems provide accurate nitrox mixtures. Membrane systems require the least amount of training.
