Abstract: A system for managing an oxygen generating system including an oxygen storage tank, a compressor, and groups of at least one oxygen generator, wherein the oxygen generating system is configured for supplying a sustained flow of a gaseous mixture comprising mostly oxygen. The system includes at least one controller device. The at least one controller device is configured to control group circuits based at least upon a pressure. Each of the group circuits are for providing power to a particular group of the groups of at least one oxygen generator. The at least one controller device is also configured to control a circuit for providing power to the compressor.

Abstract: A controller device for managing an oxygen generating system. The controller device is configured to: receive a first pressure signal associated with a first pressure; determine the first pressure to be less than or equal to a startup threshold pressure, said first pressure associated with a pressure of an oil-less tank; send a signal to switch a first circuit on, said first circuit for providing electrical power to a bank of oxygen generators; send a signal to switch a second circuit on, said second circuit for providing electrical power to an oil-less air compressor; receive a second pressure signal associated with a second pressure; determine the second pressure to be greater than or equal to a shutoff threshold pressure, said second pressure associated with a pressure of the oil-less tank; send a signal to switch the first circuit off; and send a signal to switch the second circuit off.
