Pass Box Interlocking System

Listing ID #3911278

in the process of material transfer from unclassified area to classified area pass boxes are used. The doors are interlocked such a way that doors cannot be open at the same time, due to which pressure losses and bacterial contamination doesn't takes place throughout the material transferring process. The prevention of simultaneous access of doors is been achieved by our pass box controller by ensuring that when one door for a pass box is open then other doors closed.
