The pass-through desiccator cabinets can be installed within a cleanroom or inventory room wall or can be positioned between two aisles in assembly rooms allowing access to stored materials from both sides.     
     
The compartments can be fully isolated from each other as each compartment utilizes an inlet and bleeding valve for introduction of nitrogen gas or CDA to complete purging system to reduce the moisture level down to 0%.     
     
Or the compartments can be connected to each other through some perforations between chamber dividers so they can be used with one set of inlet and bleeding valve along with a single channel automatic purge control unit.     
PCU or purge controller can provide automatic low-humidity control capable of measuring and displaying humidity inside the pass-through cabinets in the range: 5-100%RH.
