A dehumidifier developed for regulating the moisture content in a closed chamber. The device accomplishes a reduced level of moisture from normal to 0% in the chamber effectively with the aid of moisture adsorbent and an air flow regulating system. The device employs a moisture adsorbent as moisture adsorbing medium and the continuous adsorption of moisture is achieved by the heating and cooling of the adsorbent with the help of a heating coil and a fan that are regulated by a electric switching means working under the principle "The increase in the conductance of adsorbent is proportionate to the increase in moisture content". The device attains a reduced level of moisture in the chamber effectively by using an air flow controlling system which controls the air flow between the device, the outer atmosphere and the closed chamber. The prolong usage of the moisture adsorbent with consistence efficient performance is fulfilled by the filters which fixed on the device for purifying the air coming inside it. Thus, the equipment can be operated at any conditions.
