  • Coating of the ECS primary heat exchanger (PHX) with low temperature catalyst for ozone and/or volatile organic compounds (VOC) and/or carbon monoxide conversion
    Patent number: 10493820
    Abstract: A heat exchanger assembly includes a main heat exchanger that receives a main hot air; a secondary heat exchanger operatively adjacent to the main heat exchanger; wherein the secondary heat exchanger receives a secondary hot air; wherein the main hot air and the secondary hot air are from two different, direct air sources; wherein a hot air channel of only one of the main and the secondary heat exchangers includes a catalytic coating; and a temperature control that controls the temperature of only one of the main hot air and the secondary hot air into the hot air channel.
