This system includes an industrial screw compressor that supplies air at 12 bar pressure to a membrane, which separates nitrogen from oxygen, allowing for an oxygen concentration of up to 40%. The enriched air can then be compressed to 232 bar when used with a high-pressure compressor. The oxygen concentration at the outlet can be adjusted from 22.4% to 40% using a valve located on the top of the compressor. An oxygen analyzer is provided to check the accuracy of the oxygen level and make adjustments with the appropriate valve.
