Abstract: Relative humidity within a machine enclosure is controlled by means of a desiccant and a circulatory breather flow through the enclosure walls. The desiccant absorbs moisture during power off periods to keep the relative humidity down. During power on periods the enclosure temperature rises, which drives off the absorbed moisture from the desiccant. Operation of the machine also creates a pressure differential between two breather orifices in the enclosure walls so that there is a circulatory exchange of air between the enclosure and atmosphere. If the desiccant has absorbed a significant amount of moisture during power off periods, the moisture concentration within the enclosure will exceed that outside and there will be a net expulsion of moisture to partially recharge the desiccant.
