ABSTRACT:
An air desiccating apparatus (13) consists of a tank (1') which is filled with a hygroscopic desiccator substance and thermally insulated relative to its surroundings and exhibits a heater element (8'), by means whereof the desiccator substance can be regenerated by heating and evaporation. To permit such an apparatus (13) to be used also in warm rooms (25.degree. C. for example) and at very high air humidity, measures are adopted for cooling the desiccator substance with ambient air during the desiccation process. Particularly if the thermal insulation of the tank (1') results from the fact that it is surrounded by a condenser bell (15) and the latter in turn by a housing (17), whereby the steam produced during regeneration can be condensed, it is proposed that the tank (1') be penetrated by cooling pipes (3'). A fan (21) forces cooling air upwards through the latter and positively down again between the external surface of the tank and the condenser bell (15). A desiccated air consumer can be supplied uninterruptedly by the alternate service of two desiccators (13).
