Product Introduction

The Interlocked Cleanroom Door combines a flush hygienic leaf and sealed frame with concealed door-position sensing, monitored electric locking and a controller-ready cable path. When paired with another door, the logic prevents simultaneous opening and preserves the pressure buffer inside the airlock. Local indicators and emergency release functions provide clear operating feedback without cluttering the clean-side surface.

Key Features

Integrated position sensor gives the interlock controller a reliable open-or-closed signal.

Monitored electromagnetic or bolt locking confirms whether the leaf is secured.

Flush cable routing keeps electrical connections protected inside the frame.

Local status indicator communicates when the opposite door is occupied or released.

Continuous gaskets support pressure separation after the control sequence completes.

Customer Product Concerns

Two airlock doors opened together collapse the intended pressure buffer.Interlock logic holds the second monitored lock until the first door is securely closed.

Operators cannot tell why a door remains locked.Local red-green indicators communicate door availability and cycle status.

Surface-mounted wiring creates cleaning obstacles around the frame.Prepared concealed cable channels carry sensor, lock and indicator wiring inside the assembly.

A misaligned leaf sends unreliable status signals to the controller.Adjustable concealed sensors and controlled closing bring the door consistently to its monitored position.
