Desiccator; NitroPlex, Stainless Steel, 8 Chambers, 47" W x 21.5" D x 65.5" H, Floor, Series 400

• Desiccator cabinet with automatic, multi-chamber humidity control, down to 0% RH

• 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

• Simultaneously minimizes operating costs by only 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.

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.

• 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 Designs:

• Conforms to DOD Handbook 263, MIL-SPEC 1686 and 1772 with selection of proper accessories.

• Durable 304 stainless steel design is ideal for sterile and ESD-safe biomedical applications such as storage of medical device components with sensitive micro-electronics. Corrosion resistant 304 SS withstands frequent sterilization, and won't shed or accumulate particles.

Cabinet:

• 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.

Doors:

• Access doors with 304 stainless steel reinforced frames extend desiccator cabinet's service life and provide a tight seal.

• Static-dissipative PVC windows safely conduct surface charges to ground, protect against particle aggregation, and have broad chemical resistance for easy sterilization.

• 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 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.

Features and Benefits

NitroPlex Explained

NitroPlex: Faster Recovery Time, Increased Yields!

The NitroPlex™ Desiccator Control System provides state-of-the-art automated humidity control to guarantee the integrity of stored components.

Each microprocessor-based multiplexed sensor/display module, one installed in each desiccator chamber, enhances desiccator performance and economizes on nitrogen expenses. It contains a miniaturized moisture sensor that reads the internal humidity level within ± 2% of full scale. The LED readout displays this value or the programmable set point for that chamber. The set point is adjustable from ambient to 0% RH (the unit does not add moisture).

When the humidity climbs above the set point in any chamber, the NitroPlex automatically directs a high-flow purge of clean, dry nitrogen only to the chamber where it is needed, and only for as long as necessary to bring the humidity back below the set point value. An adjustable time delay maintains the high-flow purge for a short period of time--long enough to purge any moisture or contaminants that may have entered—and then shuts off, economizing on nitrogen use.

The Automatic RB® (Relief/Bleed) Valve, installed on each chamber, ensures that moisture and contaminants quickly exit the chamber into which they enter and do not migrate to others. It also protects the cabinet against overpressures.

Status alarms are included in each NitroPlex module to warn the user if any door is left open or if the system has been in high purge mode too long, a condition that could indicate an interruption in the gas supply.

This ultra-efficient purging system ensures that your desiccator system maintains the conditions you specify, even during periods of frequent access or very high ambient humidity. Each time a part is accessed and a door closed the system recovers the desired humidity level in a fraction of the time required by conventional systems (see related sidebar). This reduced recovery time eliminates the risk of moisture-related damage to even the most sensitive parts.

Which critical control application can you find in your facility?

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.

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.

High Caliber Hardware

Don’t be concerned about the quality, durability, and craftsmanship of your latches, ports, glides and hinges. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware.

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

Available NitroPlex Module automatically monitors and maintains low-RH set point to protect delicate samples while conserving nitrogen purge gas.

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.

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

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.

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.

Stainless Steel Racks for Adjustable Shelf Storage Desiccators

Unlike common chrome-plated hardware, durable 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.
