Features and Benefits

Smart Desiccator Essentials


Smart Performance—and Big Savings!

Testing demonstrates the cost benefit of the SmartDesiccator's automated nitrogen control system. Our total nitrogen consumption test was first conducted on a desiccator equipped with a flowmeter, and then with a SmartDesiccator™ control system, under the conditions specified in the chart.

Result: SmartDesiccator™ uses 22% of nitrogen consumed by standard cabinet—a 78% saving!

Smart Desiccator Time to Achieve 10% RH chart
  • Ambient Humidity: 60% RH
  • Temperature: 70°F (21° C)
  • RH Setpoint: 10% RH
  • Test Period: Achieve setpoint and then maintain it for 24 hours
  • Chamber Access: Door opened once every 30 minutes; remains open for one minute
SmartDesiccator™ (blue line on chart)
  • To achieve setpoint: 85 cubic feet (2.4 cubic meters). Required 30 minutes @ 170 CFH (4.81 m3/hr) on high flow.
  • Maintain for 24 hrs: 40 cubic feet (1.1 cubic meters)
  • Total N2 Consumed: 125 cubic feet (3.5 cubic meters)
  • Desiccator with 0 - 20 SCFH flowmeter (red line on chart)
  • To achieve setpoint: 85 cubic feet (2.4 cubic meters). Required over 4 hours @ 20 CFH (0.57 m3/hr).
    Note: Setpoint measured with a hygrometer, since this set up does not monitor humidity level.
  • Maintain for 24 hrs: 480 cubic feet (13.6 cubic meters)
  • Total N2 Consumed: 565 cubic feet (16 cubic meters)

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.

Smart Module with LED Display

Upgrade your desiccator to an automatic nitrogen control system with Terra's economical, programmable Smart Module.

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.

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.

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

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 Storage Racks

Stainless steel racks resist chipping and scratching from sliding or removable shelves, won't produce contaminants
