<p>An apparatus (70,75) for providing air at a given temperature to an air separation module (215,315) has a first path (240,340) for delivering air having a first temperature to the air separation module, a second path (225,325) for delivering air having the first temperature to the air separation module, a heat exchanger (230,330) through which the second path flows, the heat exchanger modulating the temperature of the air from the first temperature to a second, lower, temperature, and a valve (245,345) for controlling an amount of air flowing through the second path whereby if the air delivered to the air separation module by the first path and the second path is below a temperature desired to run the air separation module essentially all of the air may flow through the first path.</p> |
