The invention is concerned with a device of destroying ozone in gases by employing a recuperative plate heat exchanger ( 1 ) and an integrated electrical heating element ( 19, 21 ). The recuperative plate heat exchanger ( 1 ) is equipped with at least two planes, a preheating plane ( 11 ) and a recooling plane ( 13 ), whereby the flow direction of the gas treated in the recooling plane ( 13 ) is reversed relative to the ozone-containing gas in the preheating plane ( 11 ). Preferably, the flow directions of the preheating plane ( 11 ) and the recooling plane ( 13 ) cross over. The electrical heating element ( 19, 21 ) is situated in a reaction chamber ( 3 ) and heats up the ozone-containing gas preheated in the heat-exchanger up to temperatures of 350° C. or more, and thus destroys the ozone within the gas almost to completion. The plate heat exchanger ( 1 ) works almost without pressure losses.
