PASS BOX CONTROLLER

Pass Box is used for material transfer from one cleanroom to another clean room. It consists of a rectangular box with two/three doors. All doors are interlocked such that more than one door cannot be opened at the same time, to prevent pressure losses and cross contamination.

Radix Pass Box Controller DXC421 achieves this by ensuring that before Door 1 of a Pass Box is opened, Door 2 and Door 3 are closed.

There are two/three LCD Display Cum Operator Panels (LCD Display Panels), one each to be mounted above each door. The panel has 2x16 backlit LCD to display door status, UV life span, CFL, FAN, UV status, etc.

DXC421 also has provision to connect UV lamp, CF lamp and FAN.
