Gas treatment component

A gas treatment component comprising a cross-flow heat exchanger and a counter-flow heat exchanger arranged in series with the cross-flow heat exchanger, wherein the cross-flow heat exchanger and the counter-flow heat exchanger each comprise a core comprising a stack of heat exchanger plates, wherein the heat exchanger plates of the cross-flow heat exchanger form first channels for a first gas flow passing the cross-flow heat exchanger and form second channels for a second gas flow passing the cross-flow heat exchanger, wherein a first distance between neighbouring heat exchanger plates forming the first channels is smaller than a second distance between neighbouring heat exchanger plates forming the second channels, wherein the cross-flow heat exchanger comprises a second outlet for the second gas flow to leave the cross-flow heat exchanger, wherein a deflector plate is arranged at the second outlet of the cross-flow heat exchanger for deflecting a portion of the second gas flow leaving the cross-flow heat exchanger at the second outlet, and wherein the deflector plate is arranged between the second outlet of the cross-flow heat exchanger and a second inlet of the counter-flow heat exchanger.
