Abstract: The invention relates to a system for drying and/or cooling an airflow, comprising: at least one cooling device for cooling an airflow, comprising:—at least one cooling channel with an inflow opening for the airflow for cooling and an outflow opening for the cooled airflow,—at least one evaporating channel separated from the cooling channel by a transfer wall and having an inflow opening which is connected for medium throughflow to the outflow opening of the cooling channel, and an outflow opening, and—means for wetting the side of the transfer wall directed toward the evaporating channel, and a drying device for drying the airflow, comprising:—a drying channel with an inflow opening for the airflow for drying and an outflow opening for the dried air-flow, wherein the outflow opening of the cooling channel of the or a cooling device and/or the outflow opening of the evaporating channel of the or a cooling device is connected for medium throughflow to the inflow opening of the drying device.

Abstract: The invention relates to a sorption dryer, comprising: at least one passage through which a gas, particularly air, is fed during use; wherein the or each passage is provided with a sorption material; heating means for heating the sorption material at least locally in order to regenerate the sorption material; a temperature gauge for measuring a temperature representative of the moisture content of the sorption material; and control means for controlling the heating means subject to the measured temperature, wherein the control means are adapted to at least temporarily deactivate the heating means when the measured temperature is higher than a predetermined temperature.
