CleanMount Basics

CleanMount BioSafe Smart Pass-Through Chamber

Don't risk operational delays or cleanroom shutdown because of a damaged door!
Terra's pass-through chambers last indefinitely, much longer than our standard product revision cycle. Pass-Through doors, however, are subject to damage, and ordering a legacy replacement can be costly and disrupt cleanroom operation. To avoid these problems, order replacements at the time you purchase the pass-through chamber; simply add “-RH” (for right-side hinge) or “-LH” (for left-side hinge) to the part number of the chamber.
CleanMount™ Design Allows Servicing or Replacement without Cleanroom Shutdown!
The simplicity of this CleanMount clamping system makes removal of the pass-through chamber just as easy as installation. If the wall cut-out framing is properly sealed prior to installation, the pass-through can be quickly removed and replaced without ever having to shut down the cleanroom. Maintain the positive-pressure differential and protect the cleanroom environment by sealing off the "dirty side" with plastic sheeting prior to removal. Loosen the lag bolt so that the pass-through lifts out of the wall without contaminating the room. Once out, the pass-through can be serviced, modified, or even replaced with an upgraded version to accommodate new applications.

Lift-Off, Non-Shedding Door Hinges

Non-shedding, barrel-type door hinges allow the doors to lift off for thorough cleaning and decontamination (no tools required). Unlike industry standard continuous designs, these hinges comply with strict ISO levels.

Non-Outgassing Bio-Seal

The BioSafe® pass-through door design features a non-outgassing polyurethane seal, potted flush with the interior door surface, that seats against a raised edge.

Concealed Automatic Interlock Simplifies Cleaning

Automatic door interlock is hidden and isolated from the main chamber. This provides an unobstructed, smooth, and seamless interior for easy wipe down and sterilization. Ideal for critical bio/pharmaceutical processing.

BioSafe®: Terra's Ultimate Cleanliness Rating

Terra's BioSafe products are designed for the most critical applications: no gaps and crevices where microbes colonize, rounded corners for easy disinfection, won't produce contaminants during sterilization, and exceeds cGMP, IEST, ASTM and ISO 14644-1 requirements.

Flush-Mount Design Prevents Dust Accumulation

CleanMount® pass-throughs hug the cleanroom wall, eliminating gaps that collect germs and particle and making them ideal for critical bio/pharmaceutical cleanroom use.

CleanMount™ Quick Install System

Clean-Mount™ clamping design allows pass-through installation flush against a cleanroom wall in a few minutes, without drilling into the finished wall; mounting brackets clamp flush against walls of any thickness.

Easy Installation Simplifies Cleanroom Commissioning

Installing conventional passthroughs can be very messy, making it impossible to perform while a cleanroom is operational. Terra’s innovative CleanMount® fastening system changes that, allowing for clean installation without drilling or penetrating the cleanroom wall. Framing a CleanMount® passthrough chamber on a finished cut-out eliminates the need for cleanroom shut-down during installation or service.

CleanMount® Lipless Chamber Eliminates Clearance Obstructions

Instead of welded seams, the corners of the CleanMount® pass-through interior are coved to eliminate dust and germ traps. The lipless opening presents no clearance obstructions and further simplifies cleaning.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

Removable Cart Ramps on Floor-Mount Models

Floor-mount pass-through chambers include dual-side stainless steel cart ramps, sloped on three sides, that are removable for easy cleaning.

  • Interlock Status Lights

    Prevent operator damage! A green light bar indicates the door is available for use, with the electronic interlock disengaged. The bar turns red when the opposing door is open to indicate the electronic interlock is engaged.
  • UV Sanitizing Module

    Provides a timed cycle of 254 nm Ultra-Violet (UV) radiation to neutralize bacteria, viruses and mold spores within line-of-sight of the light fixture.
  • LED Recessed Light

    Activates when either pass-through door opens; flush with the wall surface, covered by a static-dissipative PVC lens.
  • 90° Corner Design

    Custom door configurations are no problem. Install Smart pass-throughs in corner walls, with door swings in either direction.
  • Video Camera

    Interior HD video camera records continuously or upon door-opening; can also be used for remote monitoring the transfer chamber.
  • Passthrough Ventilation Exhaust Ducts

    Adding a duct flange to the top of the passthrough allows the chamber to be ventilated by a remote blower. The ULPA-filtered inlet, housed in a perforated stainless steel cage, provides the necessary make-up air without contaminating the chamber.
  • Infrared Load Sensor

    Infrared beams detect objects placed inside the transfer chamber and can be used to trigger an audible alert. The crossed red lines depict the non-visible trigger lines between the IR transmitters and receivers.
  • Automatic Door

    Hands-free operation of the pass-through door, governed by the electronic interlock; automatically closes based on delay timer.
  • Intercom System

    Built-in intercom system lets users easily call and communicate between rooms. No more knocking on windows, shouting, or awkward sign language.
  • LCD Message Panel

    Displays critical environmental information related to the interior chamber such as temperature and relative humidity (customizable).
  • ULPA-Filtered Air Shower

    High-velocity, ULPA-filtered air dislodges surface-deposited contaminants and exits the chamber through a filtered exhaust.
  • Support Brackets for Pass-Through Chambers

    Stainless steel support brackets are recommended for pass-throughs deeper than 24". Brackets fasten to the wall and the body of the chamber rests upon the horizontal bar; no fasteners are used on the pass-through itself.
