Product Details

• Gas-purged, general purpose desiccators with high-uniformity automatic RH control systems

• Full cabinet RH control

• Acrylic or static-dissipative PVC

• 3 chambers; benchtop

• Chambers: 16.5 & 22" W, 16 & 22" D, 11.5" H

• Cabinets: 17 & 24" W, 19 & 25" D, 36" H

• IsoDry Humidity Control system offers greater RH uniformity and significantly speeds up RH recovery times

• IsoDry Gas Dilution Module (patent-pending) rapidly dilutes the air in the cabinet with dry nitrogen gas

• IsoDry Dual Purge system features both high- and low-flow operation for efficient use of nitrogen

• IsoDry NitroWatch controller features programmable set-point control and monitors humidity in the cabinet via the included RH sensor

• High-flow nitrogen gas purging activates when RH rises above the programmed set-point or when a door opens

• 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

Which critical control application can you find in your facility?

Power Requirement 24V: draws power from IsoDry Dual Purge System
Fans 120 CFM each
Display 5-digit LED
Display Resolution ± 0.1%RH
Sensor Accuracy ± 2% RH @ 20°C
Measuring Range 0 - 100% RH
Calibration None required for standard accuracy range

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.

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 Ensure Uniform Humidity

IsoDry Gas Dilution Module enhances relative humidity uniformity throughout the desiccator cabinet and speed up moisture removal when a door opens

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.
