Abstract:
A device for reducing the presence of moisture within an enclosure including a heat source comprising:a) a housing containing desiccant; b) an air-impermeable and water vapor permeable layer incorporated with said housing and oriented adjacent said heat source; c) a vent hole in the device providing a pathway from inside the enclosure to the desiccant; d) a diffusion tube having a first opening adjacent to said desiccant and a second opening adjacent to the atmosphere external to the housing, said diffusion tube creating a pathway from the desiccant in the interior of the housing to the external atmosphere; and e) a means for locating said housing so that the heat source can heat the desiccant to a temperature whereby the moisture is driven from the desiccant.
