Product Details
Product Details
  • Available ISO Ratings: ISO 7, ISO 8
  • Smart® gas-purge desiccator cabinet automates low-humidity control down to 0% RH
  • Ideal for long-term storage of samples or components without fast recovery rate requirements
  • Gas control system auto-adjusts nitrogen purge to maintain sub-ambient humidity set point
  • Fast-acting and economical; maintains below 10% RH with 78% less nitrogen than manual flow meter
  • Fully integrated turnkey system takes seconds to install and program
  • Smart® nitrogen desiccator cabinet features automated RH control that toggles nitrogen inflow (binary on/off) for fast setpoint response. Minimizes moisture and oxygen related degradation to optimize yields.
  • Mini LED display and built-in RH sensor simplifies installation. Operation requires only one gas line and one low voltage power connection.
  • Cabinet Design:
  • Innovative wall fusing technology on plastic designs creates a rigid, durable structure for improved weight capacity and resistance to high-frequency vibrations.
  • Choose chamber material to match your application and budget:
  •        Low cost acrylic.
  •        ESD-safe and chemical resistant static-dissipative PVC (SD-PVC).
  •        Heavy-duty 304-grade stainless steel for sterile and ESD-safe applications.
  • Automatic relief/bleed (RB) valves continuously bleed off excess internal gas in only one direction. Helps maintain a slight positive pressure inside the desiccator cabinet without allowing contaminants inside.
  • Built-in shelf rack provides high-capacity, organized storage (removable shelves sold separately).
  • Door Design:
  • Stainless steel door frame increases structural rigidity for a tighter seal and longer service life.
  • 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.
  • Durable 304 stainless steel hinges eliminate corrosion, flaking, and contamination that commonly occur with ordinary chrome-plated hinges.
  • Optional Accessories:
  • Locking lift latches: specify one per chamber.
  • Nitrogen generator: provides a continuous, reliable supply of pure, dry nitrogen to eliminate dependence on bulky canisters.
  • ErgoHeight™ automatic height adjusting table: perfect for workstations holding heavy or fragile equipment that require frequent height adjustment.
  • Sliding trays: choose trays to match your application and budget. Stainless steel trays are easy to clean and ESD-safe. Perforated designs help enhance gas distribution inside the cabinet while solid designs are suitable for small parts and containing spills. Low-cost acrylic trays offer greater visual transparency.
  • Replacement door(s): helps avoid costly operation delays and exposure of sensitive stored material, should a door ever be damaged and require immediate replacement.

Learn More: Smart Desiccators


Smart Performance—and Big Savings!

Testing demonstrates the cost benefit of the SmartDesiccator's automated nitrogen control system. Our total nitrogen consumption test was first conducted on a desiccator equipped with a flowmeter, and then with a SmartDesiccator™ control system, under the conditions specified in the chart.

Result: SmartDesiccator™ uses 22% of nitrogen consumed by standard cabinet—a 78% saving!

Smart Desiccator Time to Achieve 10% RH chart
  • Ambient Humidity: 60% RH
  • Temperature: 70°F (21° C)
  • RH Setpoint: 10% RH
  • Test Period: Achieve setpoint and then maintain it for 24 hours
  • Chamber Access: Door opened once every 30 minutes; remains open for one minute
SmartDesiccator™ (blue line on chart)
  • To achieve setpoint: 85 cubic feet (2.4 cubic meters). Required 30 minutes @ 170 CFH (4.81 m3/hr) on high flow.
  • Maintain for 24 hrs: 40 cubic feet (1.1 cubic meters)
  • Total N2 Consumed: 125 cubic feet (3.5 cubic meters)
  • Desiccator with 0 - 20 SCFH flowmeter (red line on chart)
  • To achieve setpoint: 85 cubic feet (2.4 cubic meters). Required over 4 hours @ 20 CFH (0.57 m3/hr).
    Note: Setpoint measured with a hygrometer, since this set up does not monitor humidity level.
  • Maintain for 24 hrs: 480 cubic feet (13.6 cubic meters)
  • Total N2 Consumed: 565 cubic feet (16 cubic meters)

Critical Environment Solutions

Terra's mission is to help customers in highly regulated industries transform the world with critical environment solutions that improve health, safety, performance, and yields. These environments may comply with stringent UL, ISO, IEST, ASTM and OSHA standards and local requirements.

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.

Smart Module with LED Display

Upgrade your desiccator to an automatic nitrogen control system with Terra's economical, programmable Smart Module.

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

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.

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.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. Our product quality is enabled by high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our commitment to continuously improve.
