An apparatus for dehumidification of gas by means of a moisture adsorbing medium arranged in relative thin layers separated by heating elements for heating the adsorbing medium during regeneration. The heating element preferably comprises a sheet material having a printed circuit thereon. The adsorbing medium may be arranged in a plurality of separate chambers defined in a common housing having an inlet for gas to be dehumidified and an outlet for dehumidified gas. In operation gas to be dehumidified flows from the gas inlet through the majority of the chambers and the adsorbing medium contained therein. A small fraction of dehumidified gas is directed from the outlet through the adsorbing medium in the remaining chamber or chambers towards the gas inlet, and the adsorbing medium in this chamber or these chambers is at the same time heated by the heating elements in order to regenerate the adsorbing medium. At predetermined time intervals the chamber or chambers in which the regeneration takes place, are changed.

An apparatus for drying or dehumidifying gases and comprising a plurality of chambers each having a gas inlet end and a gas outlet end communicating with a common gas inlet for gas to be dehumidified, and with a common gas outlet for dehumidified gas, respectively, a plurality of spaced layers of a regenerable, moisture adsorbing medium arranged in each of said chambers, selectively energizeable electrical heating means arranged within each of said chambers and extending between adjacent layers of adsorbing medium therein and in heat conducting contact with said layers, unitary rotary valve means rotatable between a number of angular positions corresponding to the number of said plurality of chambers, said valve means being adapted to obstruct the communication between the inlet end of each of a minority of said plurality of chambers and said common gas inlet and to simultaneously communicate each inlet end of said minority of chambers with a gas discharge in each of said angular positions and each outlet end of said minority of chambers with said common gas outlet, whereby gas which has been dehumidified in the remaining chambers may flow through said minority of chambers from said common gas outlet to said gas discharge, and means for energizing said heating means in each of said minority of chambers while such chamber is communicated with said gas discharge. An apparatus for drying or dehumidifying gases and comprising a housing defining a plurality of separate chambers therein and having an inlet end defining an inlet for gas to be dehumidified, and an outlet end defining an outlet for dehumidified gas, each of said chambers or passages communicating at its opposite ends with said gas inlet and said gas outlet ends, respectively, a regenerable moisture adsorbing medium arranged within each of said chambers or passages, said adsorbing medium being divided into a plurality of adjacent spaced layers, selectively energizeable electrical heating means arranged within each of said chambers or passages and extending between adjacent layers of adsorbing medium therein and in contact with each such layer, means for directing gas to be dehumidified from said inlet end through a first group of said plurality of chambers or passages, said plurality of chambers comprising a first group and a second group, means for simultaneously redirecting a flow of dehumidified gas from said outlet end through said second group of chambers or passages, means for energizing said heating means in each of the chambers or passages in said second group for a period of time sufficient to regenerate adsorbing medium therein while dehumidified gas is being directed therethrough, cooling means arranged at said inlet end of the housing for cooling said gas to be dehumidified in order to condense moisture therein, heating means arranged at said outlet end of the housing for heating said dehumidified gas, and said cooling means and said heating means comprising an evaporator and a condenser, respectively, of a heat pump system.
