Claim 0:
1. A gas supply system for a controlled atmosphere incubator, comprising:
an ambient air compressor fluidly coupled to a gas mixing unit via a first conduit;
a second conduit coupling the ambient air compressor to a pressure swing adsorption (PSA) unit or a membrane filtration unit, wherein the PSA or membrane unit is configured to produce a nitrogen rich product;
wherein the second conduit further couples the PSA or membrane unit to the gas mixing unit;
a third conduit configured to allow coupling of the gas mixing unit to the controlled atmosphere incubator;
a control unit operationally coupled to the controlled atmosphere incubator; and
a first gas sensor located in the controlled atmosphere incubator and electronically coupled to the control unit,
wherein the control unit is configured to regulate flow and/or composition of a gas stream flowing from the gas mixing unit to the controlled atmosphere incubator in response to a signal from the first gas sensor, thereby maintaining a desired gas mix in the controlled atmosphere incubator.
