ABSTRACT:
An inerting system and method characterized by a primary air separation module configured to communicate with an upstream source of pressurized air at elevated temperature for production of a primary downstream flow of nitrogen-enriched air to be delivered to a space to be inerted; a secondary air separation module configured to communicate with the upstream source of pressurized air at elevated temperature for production of a supplemental downstream flow of nitrogen-enriched air to be delivered to a space to be inerted when high nitrogen-enriched airflow is desired during a high flow period; and a flow controller configured to provide a warming flow through the secondary air separation module to heat the secondary air separation module to above ambient temperature during a warming period other than the high flow period.
