ABSTRACT:
In the regeneration cartridges used in respirators for carbon dioxide adsorption, heat and water are released. Especially the heat becomes a burden for the user. It must, therefore, be removed. To this end, a regenerant of the cartridge is followed by a cooling device which contains a coolant, e.g. water ice. The cooling device comprises a threaded member which is screwed into a screwthread type recess of the cartridge container. The breathing air then sweeps the cooling device in thermal contact in a spiral channel formed between the wall of the container and the insert and terminating in an outlet, as it cools the breathing air. The condensation collects at the lower point of the channel, where there is a spring-loaded drain valve, and when the valve has opened, it drains to the outside under the force of the positive respiratory pressure and a collecting condensate water column.
