Proper alignment of doors will prevent excessive gas escape and ensure door sensor alignment. Some leakage, however, is normal. Because cabinets operate under varying degrees of positive pressure, Terra door gaskets are designed to allow controlled gas escape.
All cabinets are checked prior to packaging to ensure proper door alignment. However, they can come out of alignment during shipping due to the inherent flexibility of plastic.
Doors feature sensor magnets that must be aligned with the associated sensor on the desiccator door. If these magnets are misaligned, the Dual Purge™ system may not function properly, and door seals may not seat properly, allowing nitrogen leakage.
What are the advantages and disadvantages of static control methods available today?
Why all the Static?
Static electricity is an excess or deficiency of electrons on a surface. The total number of deficient or excess electrons determines the charge on that surface. A surface exhibiting an excess of electrons is charged negatively, and an electron-deficient surface is charged positively.
How are Electrostatic Charges Generated?
Electrostatic charges are usually generated by friction between and/or separation of two dissimilar materials, at least one of which is a nonconductor or a poor conductor of electricity. The accumulated charge (stat
Terra offers a comprehensive range of application-specific desiccator cabinets and nitrogen control systems. These performance concepts will help you select the system right for your application.
Nitrogen is the standard medium for contamination-free storage because it is relatively inert—it neither reacts with stored materials nor carries moisture—and because it can be isolated and purified relatively inexpensively.
Desiccator cabinets must be set up so that an appropriate flow of nitrogen forces out all moisture- and contamination-laden air. Because nitrogen has a lower specific gravity than air, it is introduced into the upper section of the desiccator; the h
