Dehumidifier Air Handling Unit

desiccant dehumidification systems remove moisture from the air by using a desiccant; a material which easily attracts and holds water vapor. Desiccant dehumidifiers are especially well-suited for removing moisture from air at a low temperature and low humidity level. At the heart of these dehumidifiers is a desiccant wheel made up of corrugated material. Air passes through the flutes of the material, contacting the desiccant. The incoming process air stream gives off its moisture to the desiccant. The process air is dry as it leaves the wheel. The humidity-laden wheel rotates slowly into a second, smaller airstream which has been heated. This smaller exhaust airstream, known as reactivation air, warms the desiccant. The warmed desiccant gives off its moisture which is then carried away by the reactivation air. The newly dried desiccant material is rotated back into the process air, where it absorbs moisture once again
