Product Details
  • Desiccator with automatic, multi-chamber humidity control, down to 0% RH, with rapid recovery rates
  • Top-tier protection of moisture-sensitive components for longer shelf life and lower rejection rates
  • Separate RH sensors in each chamber provide chamber-by-chamber set-point programming and display
  • Minimizes operating costs by supplying nitrogen gas where and when it’s needed
  • Isolated chambers eliminate impact of moisture influx on other chambers when one door opens
  • NitroPlex™ desiccator cabinet control system drastically speeds up system recovery time for the most demanding low-humidity applications, when every second of moisture exposure counts.
  • The automatic humidity control system monitors and displays relative humidity in each individual chamber for faster set-points and improved efficiency with reduced consumption of nitrogen gas.
  • Choose from 4 cabinet materials for your unique application (custom materials available on request):
  •        Low cost acrylic
  •        Amber acrylic for light-sensitive applications
  •        ESD-safe static-dissipative PVC (SD-PVC)
  •        304 stainless steel for sterile, ESD-safe applications
  • How Nitroplex™ System Works:
  • High-accuracy, miniaturized humidity modules are installed in each chamber of the cabinet to provide independent monitor/control capability.
  • Each module is programmable to maintain a humidity set point from ambient down to 0%RH. Each module also features a miniature fan with super silent micro-motor technology to help mix and circulate nitrogen in the chamber.
  • Nitrogen is directed only where and when it’s needed to keep the %RH level below the user-specified set-point.
  • The influx of nitrogen gas pressurizes a chamber, causing moisture-laden air to be displaced and released through the automatic relief/bleed (RB) valves. This steady bleed causes the concentration of dry nitrogen gas inside the desiccator to increase until the desired RH level is reached.
  • When the RH set-point is reached, the system reverts from high-flow to low-flow nitrogen gas supply to maintain the set-point and conserve nitrogen.
  • When a door is opened, or when the relative humidity (RH) climbs above set-point level, the system re-activates high-flow to accelerate moisture removal.
  • The LED displays on a module will flash warning signals any time a chamber’s door is left open for too long or if the system remains in purge mode for too long.
  • ESD-Safe Design:
  • Grounding is not standard on all designs, choose static-control options/designs to protect sensitive materials against ESD.
  • Conforms to DOD Handbook 263, MIL-SPEC 1686 and 1772 with selection of proper accessories.
  • Cabinet Design:
  • Automatic RB™ (Relief/Bleed) valves on each chamber relieve excess pressure inside the cabinet without allowing outside air or contaminants inside.
  • Stainless steel wire racks allow shelves to be positioned at 1” increments to accommodate different part sizes inside the nitrogen dry box; Shelves can also be removed and used as carrying trays.
  • Dual-side access nitrogen cabinet options available.
  • Door Design:
  • Access doors with 304 stainless steel reinforced frames extend desiccator cabinet's service life and provide a tight seal.
  • Santoprene® “e”-shape non-outgassing rubber gasket firmly compresses to eliminate leaks. The one-piece resilient rubber gasket maintains its shape after compression and won't flatten, warp, crack, or degrade like ordinary foam gasket. Gasket is also mechanically attached to the door frame to avoid adhesive failure common with gasket tapes.
  • Heavy-duty lift latches prevent metal-on-metal scraping common with rotary latches; chrome-plated included standard; upgrade to all-stainless steel (304 or 316) to minimize scratching, corrosion and contamination resulting over time that can occur with chrome-plated latches.
  • Optional locking lift latches also available - specify one per chamber.
  • Durable stainless steel hinges eliminate corrosion, flaking, and contamination that commonly occur with ordinary chrome-plated hinges.
  • Order replacement door(s) to ensure uninterrupted service should a door ever be damaged and require replacement.
  • Requires:
  • (1) NitroPlex™ module per chamber
  • Optional Accessories:
  • Nitrogen generator: provides a continuous, reliable supply of pure, dry nitrogen to eliminate dependence on bulky canisters.

Stainless Steel Racks for Adjustable Shelf Storage Desiccators

Unlike common chrome-plated hardware, durable electropolished stainless steel racks for adjustable shelf storage desiccators help maintain a contamination-free storage environment. They resist corrosion and chipping/scratching from the sliding removable shelves.

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.

Automatic RB Valve

During normal operation, it allows a continuous low-level release of gas to maintain a positive pressure. It also functions as a check valve to ensure that air and contaminants cannot enter the enclosure in the event of a momentary negative pressure.

NitroPlex™-Ready for Critical RH Control

UL-listed NitroPlex™ module automatically monitors and maintains low-RH set point to protect delicate samples while conserving nitrogen purge gas.

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

NitroPlex Humidity Control Modules

NitroPlex systems feature individual humidity sensors with LED displays above each chamber door. Each sensor can be programmed with a different humidity set-point level.

Stainless Steel Desiccator Cabinet with Racks and Shelving

All-stainless steel Series 400 Desiccator cabinets include stainless steel wire racks and a perforated pull-out shelf; order additional perforated or non-perforated shelves to suit storage requirements.

Individual RH control for Each Chamber

NitroPlex automated system for each chamber controls RH levels down to 1%. Directs nitrogen to individual chambers to maintain their humidity levels below set point. Cuts operational cost by reducing nitrogen consumption; protects products by cutting RH recovery time and moisture exposure.

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.

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.
