Summary
- Available Certified ISO Grade™ Designs: ISO 6, ISO 7, ISO 8
- Desiccator cabinet with gas dilution fans for fast, uniform moisture removal, down to 0%RH
- Dilution fans quickly and efficiently mix nitrogen through cabinet to reduce N2 consumption
- Eliminates moisture "blind spots" that cause large RH deviations between different chambers
- Automatic humidity control system continuously monitors user-specified RH set-point inside cabinet
- Ideal for drying of heat-sensitive samples, such as tissue and bone allografts
- IsoDry® desiccator cabinets incorporate a unique, patented nitrogen purge system to achieve faster and more uniform low-humidity conditions throughout the cabinet.
- The desiccator cabinet includes a moisture sensor that connects to a separate automatic RH control system to maintain sub-ambient, user-specified humidity threshold down to 0% RH.
- How Isodry® System Works:
- High-purity nitrogen gas feeds into the desiccator cabinet and is mixed by built-in fans with existing air inside the cabinet.
- The gas dilution fans continuously circulate and mix dry nitrogen throughout the cabinet to eliminate moisture "blind spots" and further dilute moisture present inside the cabinet.
- When a door is opened, the door sensor triggers the fan to turn off to prevent outside air from being circulated through the cabinet. When the door is closed: the fans turn back on to accelerate removal of moisture-laden air.
- The influx of nitrogen gas pressurizes the cabinet, 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 RH climbs above the set-point, the system re-activates high-flow to accelerate moisture removal.
- All chambers within the cabinet share the same air and thus share the same humidity level of the cabinet (+/- 3% RH from set point at ideal conditions).
- Grounding is not standard on all designs, choose static-control options/designs to protect sensitive materials against ESD.
- Static-dissipative PVC (SD-PVC) design features bonded dissipative layers that resist abrasion and retain surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years). SD-PVC also eliminates static-cling to help maintain clean surfaces.
- Conforms to DOD Handbook 263, MIL-SPEC 1686 and 1772 with selection of proper accessories.
- Cabinet Design:
- Innovative wall fusing technology creates a rigid, durable structure for improved weight capacity and resistance to high-frequency vibrations.
- 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; shelves can also be removed and used as carrying trays.
- 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 304 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:
- Gas dilution module requires connection to IsoDry® humidity controller for operation: either IsoDry® Dual Purge System and IsoDry® NitroWatch®, or IsoDry® Smart® Controller (order either system separately).
- Optional Accessories:
- Nitrogen generator: provides a continuous, reliable supply of pure, dry nitrogen to eliminate dependence on bulky canisters.
- Includes:
- (1) Gas dilution module. Gas dilution module (24V) and sensor are pre-installed and pre-wired for quick connection with Terra’s automatic humidity control systems: DualPurge and NitroWatch®.

IsoDry® Desiccator Cabinet by Terra Universal
IsoDry® desiccator cabinets are the latest innovation in desiccators from Terra Universal. Many conventional desiccators depend on unassisted gas displacement. This mode of operation can significantly inhibit RH control, drive up operating costs, and increase the risk of damaged stored materials. The driving concept behind IsoDry is that unassisted gas displacement is significantly slower without a substantial physical force to actively mix nitrogen gas through the entire cabinet.

Features and Benefits
Gas Dilution System Ensures Uniform Humidity
IsoDry Gas Dilution Module enhances relative humidity uniformity throughout the desiccator cabinet and speeds up moisture removal after doors are closed.
Smart Performance for Big Savings
IsoDry's forced dilution system drastically improves moisture removal to quickly and efficiently attain low RH set-points. At 10% RH setpoint, IsoDry cuts recovery time and Nitrogen consumption by 80% compared with an unassisted system.
IsoDry Gas Dilution Module
IsoDry Gas Dilution Module enhances the relative humidity uniformity throughout the desiccator cabinet.
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.
Lift-Off Hinges
Lift-off hinges facilitate door removal and door replacement. Constructed of 304 stainless steel for easy cleaning and sterilization, lift-off hinges provide a unique method of door removal for cabinets without the need for extra screws and tools.
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 outside air.
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.
Rapid Drying of Hygroscopic Material
Terra's gas-purged desiccators utilize a rapid flow of inert nitrogen to quickly dry hygroscopic samples and components
