  • Patent number: 11035768
    Abstract: In a nitrogen generator, multiple, concurrent gas pressure monitors constantly and simultaneously monitor gas pressures at key points in the nitrogen generation process, and a controller generates an alarm when the pressure at any point falls below a respective predetermined pressure level, and remains there for longer than a respective predetermined duration. In some embodiments, a run time of the nitrogen separation unit is additionally monitored. Additionally, in some embodiments, if the output pressure of nitrogen gas falls below a predetermined pressure level, a bypass route is activated to route compressed air directly to the output, thus sacrificing nitrogen gas purity but maintaining required minimum pressure for downstream systems.
