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.

What's Your Application?

The standard NitroPlex™ system provides unsurpassed moisture control in dozens of storage applications. Temperature, gas or biological sensors expand the range of critical operations.

  • Microelectronics components, SMDs, hybrid packages
  • Storage of PCBs for rework
  • Pharmaceutical R&D studies
  • Kitting of high-precision watch components
  • Pass-through transfer of night-vision electronics
  • Lithium battery development
  • Humidity testing of cosmetics
  • Accelerated life testing of ICs
  • Animal inhalation and toxicology research
Which critical control application can you find in your facility?

Stainless Steel Door Frame

Stainless steel-reinforced door frame with non-adhesive, "e-profile" gaskets ensures a long service life; shown on Series 400 Stainless Steel NitroPlex desiccator.

Ergonomic LiftLatches

Prevents hinge and door damage caused by the twisting and turning and applies uniform pressure to the non-adhesive door gasket; available with locking mechanism.

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.

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.

Built-in Plenum Distributes Dry Gas to Each Chamber

Manual flowmeter or automated system controls nitrogen flow rates to maintain RH across entire cabinet. Built-in plenum distributes dry gas to each chamber.

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.

Desiccator Access

Single-side access features a door opposite a non-opening rear wall, often with a plenum chamber for uniform gas distribution. Vacuum desiccator access is typically via a removable top. Dual-side access lets operators on both sides access stored contents.

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.
