Electronic Auto-Desiccator Cabinets feature a permanent desiccant which automatically regenerates for worry-free storage or drying. The horizontal and vertical models are made of clear acrylic and have the desiccant located in the control unit; the desiccant is automatically regenerated by a 30-minute cycle every five hours to lower humidity to 30 to 40%. The Dry-Keeper Plus vertical cabinet is made from nontransparent, insulated ABS plastic and has an enclosed permanent desiccant; the electronic controller lowers relative humidity inside the cabinet to 20 to 30% in six hours (based on unloaded, continuous operation).
