• 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 applications that permit chambers to share the same air throughout cabinet
• 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 also 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.
• 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 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.
• All chambers within the cabinet share the same air and thus share the same humidity level of the cabinet (+/- 10% RH from set point).
• 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:
• 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.
• Doors:
• Access doors with 304 stainless steel reinforced frames extend desiccator cabinet's service life and provide a tight seal.
• Doors include one-piece non-adhesive Santoprene® “e”-shape rubber gasket for tight seal to prevent outside air from leaking in; gaskets is non-outgassing and will not take a set or keep an impression.
• 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).
• Includes:
• (1) RH sensor and (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®.
• (2) Stainless steel racks and (1) automatic R/B valve per chamber.
• (1) Perforated stainless steel shelf; order additional shelves separately
• Use online System Builder to select other desired shelves, gas controllers, stand and accessories.
