Kitting Tray Desiccator Cabinet
Standard Features
  • A Grounding Terminals
    Standard on static-dissipative PVC chambers to prevent electro-static discharge (ESD)
  • B Plenum Chamber
    Located in rear of cabinet, plenum ensures uniform flow of nitrogen gas to all chambers; minimizes moisture migration
  • C Grounded Door Latch
    Prevents ESD damage to stored parts (standard on static-dissipative PVC cabinets)
  • D Tamper-Proof Hinges
    Tamper-proof stainless steel hinges
Optional Features
  • 1 Dual Purge™ System
    Provides a variable flow of nitrogen purge gas: high to recover set point, low to conserve nitrogen
  • 2 NitroWatch® RH Controller
    Monitors internal humidity; activates a high-flow purge when RH climbs above set point
  • 3 Stainless Steel-Framed Doors with One-Piece Gasket
    "e"-profile gasket mechanically attached to stainless steel reinforcement frame to prevent outgassing adhesives; one-piece design won’t slough or separate
  • 4 Door Sensor Switches
    Activate high-flow purge when a door opens to recover RH set point
  • 5 Automatic RB® Valve
    Prevents overpressure; acts as a check valve (one included per chamber)
  • 6 Stainless steel racks
    Stainless steel racks support various tote-box sizes
  • 7 Stand
    Powder-coated or 304 stainless steel; 4” or 12” high; casters available

Not Shown: Nitrogen generator provides un uninterrupted supply of nitrogen up to 99% pure to eliminate reliance on bulky canisters

Features and Benefits

Automatic Relief/Bleed Valve

Terra's Automatic Relief/Bleed (RB) Valve opens up at 0.01 PSI, relieving overpressure that could damage desiccators; also works as a check valve to prevent influx of room air.

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.

Reinforced Doors with Non-adhesive Gaskets

Stainless steel door frames extend desiccator life; one-piece fused gaskets are non-outgassing, will not creep or sag

Built-in Plenum Distributes Dry Gas to Each Chamber

Manual flowmeter or automated system controls nitrogen flow rates to maintain RH across entire cabinet. Built-in plenum distributes dry gas to each chamber.

Durable Embedded Static-Dissipative Layers

Terra's SDPVC features bonded dissipative layers that resist abrasion. SDPVC desiccators retain their surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years), protecting your materials against ESD damage. Further, the control of static charges eliminates particle attractions, helping maintain clean surfaces.

Doors - The First Failure Point of a Desiccator Cabinet

Terra’s stainless steel door frames eliminate the need for internal reinforcements, which create particle surfaces and compromise cleaning. Unlike other doors with glue-on anti-bow pieces, Terra’s doors use no adhesives. This eliminates particle traps, sources of outgassing—and extends the strength and service life of the desiccator.

Desiccator Plenum Chamber For Uniform Gas Distribution

Multi-chamber desiccator cabinets include a perforated plenum to minimize back fill, ensure uniform gas distribution to all chambers and increase cabinet strength

Highest Standards For Desiccators and Electronic Components

Terra’s desiccator cabinets and RH control systems are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

  • Universal Adjustable Equipment Base Stands

    Stainless steel or powder-coated steel, cleanroom-compliant stands easily adjust to fit industry-standard cabinets, desiccators, vacuum chambers, refrigerators, incubators and ovens. Raises equipment to ergonomic height to support disinfection and sample monitoring.
  • Relative Humidity Temperature Data Logger

    Battery-powered RH/Temperature Data Logger measures and records internal desiccator environment at specified intervals; download to a PC to meet QA/QC or regulatory requirements.
  • Tote Box; Nesting, Static-Dissipative, 23.5x 8.13 x 6

    These nesting tote boxes, shown inside Terra's Series 200 Kiticcator desiccator storage system, are available in conductive and dissipative formulations to meet static decay requirements.
  • Laboratory Nitrogen Generator

    Terra’s Nitrogen Generators provide a continuous, reliable supply of clean, dry nitrogen up to 99% pure to eliminate dependence on bulky canisters to operate desiccators and glove boxes.
  • Nesting Tote Boxes in Dissipative or Conductive Polymer

    Nesting tote boxes feature smooth, easy-clean tapered sides; select lids, ticket holders and choice of Benstat® static-dissipative blue or Bentron™ conductive black polymer.
  • Nesting Tote Boxes with Ticket Holder

    Optional static-dissipative ticket holder snaps onto tote box (specify molded snap when ordering tote boxes).
  • Desiccator Cabinet Ionizing Module

    Ionizing modules are available for desiccator cabinets, glove boxes and other enclosures to ensure static-safe storage and processing (shown: ionizing unit on 2-chamber desiccator)
  • Dual Purge™ and NitroWatch™ Work Together to Fully Automate RH Control

    Terra's Dual Purge™ and NitroWatch™ operate in tandem to precisely and automatically control the flow of nitrogen and maintain a preset humidity level (from ambient to 0% ± 1.5% RH), no matter how operating conditions may change.
  • Data Logging with 113,000 Readings at User Defined Intervals

    Terra's Smart® IsoDry® Nitro-Watch™ logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The max data file size is roughly 4 MB or 113,000 readings. This is approximately 32 hours of data when logging at 1 second intervals, 2 weeks at 10 second intervals, 6 weeks at 30 second intervals, or 12 weeks at 1 minute intervals. When the system reaches the 4MB limit, data begins to wrap, overwriting oldest data with new.
  • Plug & Play Data Logging

    Plug in a USB flash drive to your Smart® IsoDry® Nitro-Watch™ to transfer data in .CSV format. No software required.
