Smart Pass-Through™ Chamber—Single Wall

Service Alerts are wirelessly transmitted to remote plug-in chimes (remote data logging also available)

“Hello? Anyone there?”—Unless operators have a talk-through, electronic intercom or other device, they have trouble alerting a colleague on the other side of the wall to unload the chamber.

“If it won’t open, force it!”—a door left ajar locks out the opposing side, frustrating an operator’s attempt to transfer materials. Worse, an operator may mistake an interlocked door for a jammed one—and pull till it breaks!

“Power-cord spaghetti”—Terra Pass-Throughs are available with several electronic conditioning accessories to enhance operation:

Micro-filtered air showers that blow off contaminants
UV sanitizing modules that deliver neutralizing UV-C doses to microorganisms on biological samples
Ventilation modules that remove chemical vapors from items introduced into the chamber

Without a centralized power distribution unit, managing connection and operation of such modules becomes a challenge.

Power supply module (on top of "dirty"-side of chamber) simplifies integration of additional powered options, such as UV-C light or air shower.	Optional Recessed LED Light illuminates chamber during parts transfer.

Terra’s unique Smart Control Module overcomes these challenges and ensures that the pass-through is operating as intended. Its dual-side plug-in Service Alerts receive wireless signals and issue warning chimes—momentary to signal sample loading, continuous to signal a door ajar. These signals can be logged to provide a traceable history of pass-through operation.

It also provides a central point of power connection for accessories and triggers operation cycles. Dual timers allow selectable activation delays, door open delays, and cycle duration. See below for additional features.

• Electronic interlock confined in a recessed 6"H x 1.25"D compartment
• 120 or 220VAC power integration of all included options, via power control unit mounted external to transfer chamber for easy cleaning
• Door Status Alerts: Indicator light issues a solid glow when doors are closed (ready for operation) or flashes when either door is open (interlock active)
• Door Ajar Alert: Indicator light flashes at increased frequency when either door remains open longer than 30 seconds (delay time adjustable)
• Plug-In Chimes: receive wireless signals for remote audible door alerts up to 200 feet from chamber (2 units included)
