• A flowmeter installed in the Dual Purge system delivers a slow, continuous flow of nitrogen to supplement the high-flow operation

• Automatic Relief/Bleed valve releases moisture-laden air from the chamber, speeding up dilution and preventing over-pressurization

• LED display shows the current relative humidity level for the entire cabinet

• Reduces moisture-related degradation of semiconductors and electronic components

• Provides a dry storage environment for medical devices, pharmaceutical powders, and other contamination-sensitive materials

• Ergonomic, stainless steel LiftLatches do not scrape the chamber like ordinary rotary latches

• Mechanically attached, one-piece gasket does not creep or crack

• Includes stainless steel-framed doors, one automatic RB (Relief/Bleed) valve per chamber, stainless steel wire racks, and one stainless steel perforated shelf

Features and Benefits

IsoDry Explained

IsoDry Dual Purge/NitroWatch Systems

The complete IsoDry control system includes a relative humidity sensor mounted inside the chamber and a Terra's IsoDry Dual Purge and NitroWatch systems, which work in tandem to ensure fast set point recovery times (see graph above).

The Dual Purge system provides a high-volume burst of nitrogen to attain the RH set point upon system set-up. Once this set point is attained, it uses an economical low-flow purge to maintain the set point, and then activates the high-flow purge the minute a door opens to recover set point with minimal nitrogen waste. The NitroWatch provides continuous monitor/display of both measured RH and set point levels.

Status alerts built into the IsoDry Dual Purge System warn if incoming nitrogen line pressure falls below operational rates (signaling an interruption in the gas supply) or if the system remains in high-flow purge for an excessive period (signaling a door left ajar). This integrated system also provides the low-voltage power required by the IsoDry and a variable speed control for the dilution fans.

For smaller cabinets, a flowmeter kit provides an economical alternative to the automated Dual Purge/NitroWatch controller. The flowmeter kit includes a plug-in power supply for the gas mixing fans, but does not include set-point capability or RH monitoring.

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, surface-mount devices (SMDs), hybrid packages
  • Storage of printed circuit boards (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

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.

IsoDry Gas Dilution Module

IsoDry Gas Dilution Module enhances the relative humidity uniformity throughout the desiccator cabinet.

Static-Dissipative PVC Plating

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.

Ergonomic LiftLatches

Lifting latch mechanism minimizes stress on wrists and desiccator hinges; non-rotary motion generates no particles inside the storage area (optional locking model shown)

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

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.

Three-Chamber IsoDry Desiccator Cabinet

Available in three chamber sizes, these desiccators provide uniform gas distribution and reach humidity set-point quickly, ideal for moisture-sensitive samples; include racks for adjustable shelving.

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.
