15.0 Producing Nitrox
The equipment you will be using to manufacture Nitrox (oxygen rich air) will expose you to
both low and high-pressure gas. Gas, even under moderate pressures, can cause extreme
bodily harm. Never allow any gas stream to be directed at any part of your body.
15.1 Flow to Membrane and Setting Proper Pressure
1) Verify that Oxygen Analyzer calibration is
complete, LP compressor is Off, and Regulator
is at minimum pressure setting.
2) Turn on HP Compressor. Allow pressure to
build up to about 2000 psi (140 bar), then crack
open the unconnected fill whip to maintain
1500-2000 psi (100-140 bar).
3) Verify that Permeate Oxygen Analyzer and Fill
Oxygen analyzer read 20.9%.
4) Turn on LP Compressor.
5) Turn BP Regulator Knob CW
6) Adjust feed air pressure to approximately 100 psi (7 bar) to activate Heater Pressure Switch.
Increase pressure by slowly turning the regulator Knob CW or decrease pressure by turning the
Knob CCW. The heater will not turn on until Membrane System is pressurized.
7) Check the Heater Temperature Gauge to verify air temperature rises and is between 105-120 ºF
(40-49 ºC).
