Dehumidifier

The dehumidifier operate on the principle of absorption of water vapors from the air. The desiccant used is silica gel, MOC is of an inorganic substance The desiccant and substrate are arranged in a wheel-shaped rotor matrix having multiples of small parallel air passages extending through its thickness. The desiccant rotor is housed in a cabinet that is separated into process and reactivation sections. In the process section, moist air passes through the rotor, and the silica gel absorbs the moisture. To remove the moisture absorbed out of the desiccant, the rotor at lower RPM rotates crossing the reactivation zone, where the heated air stream by steam or electrical heaters is blown through the desiccant. The moisture-laden reactivation air is exhausted outside. The reactivated desiccant rotor rotates passing back into the process section to provide continuous drying of the process air and the cycle continues. In many applications, the process air is cooled before entering the desiccant rotor to enable the system to produce dry air. The reactivation air stream may be heated by electricity, steam, hot water, or natural gas depending on the application and available utilities.
