Product Details
  • Humiccator provides a humidity-regulating, economical, contamination-free way to store sensitive materials
  • Humiccator system combines Humex and Dual Purge modules to allow humidification with nitrogen gas purge
  • Dual Purge system conserves nitrogen gas and maintains constant positive pressure to block contamination inflow
  • Humex operates in tandem with Dual Purge to achieve precise humidification and %RH control
  • How Humex Works:
  • The Humex™ 2 Humidifier provides inline humidification of nitrogen or other process gas being fed into the desiccator cabinet.
  • During operation, a 20W resistance heater inside the Humex 2 vaporizes incoming water fed into a stainless steel chamber. Process gas, which enters the Humex 2 through separate 0.25"-diameter flexible tubing, is humidified with steam as it passes through this chamber on its way to the cabinet.
  • The Humex 2 humidity sensor, installed inside the cabinet, monitors the relative humidity (RH) level. As soon as the %RH falls below a user-selected threshold, a relay inside the Humex activates the heater and a solenoid that turns on the water flow. When the %RH set-point is attained, the Humex turns off heater and water flow.
  • Operation with the Dual Purge:
  • For optimal efficiency—and to conserve nitrogen— the Humex operates with Terra’s Dual Purge Variable Purge Controller.
  • In this configuration, the Humex issues a signal to the Dual Purge via a 4-connector low-voltage cable to initiate high flow (bypassing the Dual Purge flowmeter) whenever the humidity falls below the set-point. This high flow of process gas quickly humidifies the enclosure.
  • When the set-point is attained, the Humex deactivates the high flow (as well as the Humex humidification system) to conserve on nitrogen. In this low-flow purge, the flow rate is restricted by the Dual Purge flowmeter.

Smart Performance for Big Savings

IsoDry's forced dilution system drastically improves moisture removal to quickly and efficiently attain low RH set-points. At 10% RH setpoint, IsoDry cuts recovery time and Nitrogen consumption by 80% compared with an unassisted system.

Stainless Steel Racks for Adjustable Shelf Storage Desiccators

Unlike common chrome-plated hardware, durable electropolished 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.

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.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

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.

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.

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.

Highest Standards For Desiccators and Electronic Components

Terra’s desiccator cabinets and RH control systems are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. Our product quality is enabled by high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our commitment to continuously improve.

Long-Term Customers

Terra is committed to building long-term relationships with satisfied clients; 94% of orders each year come from repeat customers

  • Data Logging with 113,000 Readings at User Defined Intervals

    Terra's Smart® IsoDry® Nitro-Watch™ logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The max data file size is roughly 4 MB or 113,000 readings. This is approximately 32 hours of data when logging at 1 second intervals, 2 weeks at 10 second intervals, 6 weeks at 30 second intervals, or 12 weeks at 1 minute intervals. When the system reaches the 4MB limit, data begins to wrap, overwriting oldest data with new.
