A system for recycling cooling devices, comprising a system part for catalytically oxidizing the pure hydrocarbon compounds and chlorofluorocarbons which accumulate during the recycling of the cooling devices. According to the invention, this system part comprises two reactors, provided mutually separated in the flow direction of the gases to be treated, a first reactor being used for catalytically oxidizing the pure hydrocarbon compounds while a second reactor is used for catalytically oxidizing chlorofluorocarbons.
