Patent ID: 8147579

Claim:
An air inerting system for supplying a nitrogen-enriched air to a fuel tank on a vehicle comprising: an air separation module having an inlet for receiving air to separate oxygen and made into a nitrogen-enriched air, and an outlet for delivering nitrogen-enriched air to a downstream fuel tank on a vehicle, and there being downstream parallel flow lines downstream of said outlet, with each of said downstream parallel lines being provided with a flow control valve, and said downstream parallel lines reconnecting downstream of said flow valves to provide a source of nitrogen-enriched air to the fuel tank; and an air supply line upstream of said air separation module, and said air supply line supplying air to at least a pair of upstream parallel lines, each of said upstream parallel lines being provided with a shut-off valve, and said upstream parallel lines reconnecting downstream of said shut-off valves to supply air to a heat exchanger, air downstream of said heat exchanger passing to said air separation module.
