TDI Desiccator Ultra Nitro-Flow System

All TDI Acrylic Desiccators are constructed with Ultra Nitro-Flow compartment flow-throughs, which achieve a single pressure and atmosphere condition throughout the desiccator.  This unique design allows maximum gas flow in both the vertical and horizontal directions and reduces higher moisture humidity conditions between compartments.

This flow design allows for a single automatic bleeder valve per multiple compartment cabinet and eliminates the need for expensive outlet valves for each compartment, required in typical competitor cabinets.  The bleeder valve is located in the bottom of the lowest compartment and serves as an efficient outlet drain for the heavier high moisture atmosphere within the cabinet.  This design also allows for a single #HM40 Nitro-Save® Humidity Control Monitor sensor system for multiple compartment desiccators.

Acrylic desiccators are recommended for non electro-static discharge (ESD) sensitive storage applications.  Often these acrylic desiccators are utilized in cleanroom storage of wafers, reticles, photomasks and other contents less susceptible to ESD discharge events.

Although acrylic desiccators may attain a highly charged condition, it can be mitigated with the proper precautions.  Cleanrooms routinely maintain 45/55% relative humidity control, which provides a layer of moisture on exposed surfaces and this conductive layer facilitates discharging the static electricity to ground. TDI recommends that all acrylic cabinets include our grounding feature to accelerate these discharges.

Although static dissipative acrylic desiccators are recommended for electro-static discharge (ESD) sensitive storage applications, acrylic desiccators may be utilized as an economical alternative in certain applications.  Acrylic desiccators utilized in storing ESD sensitive contents must include stainless steel shelves, racks and compartment floor plates all properly grounded.  ESD sensitive components must be stored in ESD storage bags, totes or other protective packaging and these precautions will provide ESD protection for these components.  The acrylic desiccators remain susceptible to static charging and are not recommended for use in critical ESD assembly locations.

Selecting Your Desiccator Model
The desiccator selection process involves building the desiccator around the contents to maximize storage capacity and minimize workstation or floor space utilization.  Additionally, the selection of the best features and options to assure complete protection of the storage contents is essential in the desiccator building process.  In selecting the desiccator model, size and features, the storage contents dimensions [width / depth / height], weight and quantity should be calculated.  This information will assist in the selection of the model and desiccator dimensions for storage.

TDI is a leader in the industry for custom desiccator designs.  Our desiccator cabinet designers will work directly with you to assure complete satisfaction.  Contact TDI for Custom Width / Depth / Height Requirements
