Clear Acrylic Desiccator Storage Cabinets

Clear Acrylic Desiccator Storage Cabinets

TDI’s Clear Acrylic Desiccators provide the highest quality and most durable construction.  They meet the requirements for cleanroom and assembly component storage applications.  All desiccators are built using ¼” acrylic material.  This material is inherently inert and will not out-gas plasticizers that may contaminate cabinet contents.  All of our desiccators include the unique Ultra Nitro-Flow design.  This provides notched compartment walls and floors for uniform humidity control in all compartments.

New!  Nitro-Save® Humidity Control Monitor

TDI developed the Nitro-Save® Humidity Control Monitor as an economic, solid state system.  Accurately controls relative humidity and significantly reduces nitrogen consumption in our cabinets up to 90% in many applications. Nitro-Save® is an option available on all TDI Desiccators. 

• Accuracy: ±2% at 3-80%RH
• Silent Operation - High Reliability - No Electromechanical Switches
• Solenoid Control Valve & Internal Sensor System
• Sensor System Activates Solenoid as N2/CDA Flow Required
• Continuous In-Line Nitrogen or Clean Dry Air Required.
• Must Operate at 80 PSI (min) to 100 PSI (max) for Optimum Performance
• Reduces Nitrogen Consumption to 90% (20%RH) in Many Applications

Knowing the Difference Between Clear and Static Dissipative Acrylic

Clear Acrylic (D) is recommended for non-electrostatic discharge (ESD) sensitive storage applications. Often these 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. Clean rooms 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 acrylic cabinets include our grounding feature to accelerate these discharges.   (Acrylic Material Data Sheet)

Static Dissipative Acrylic (SD) provides complete electrostatic discharge protection for ESD sensitive cleanroom and assembly component storage. This material offers a surface resistivity of 10⁶-10⁸ Ohms/sq. and the cannot be tribocharged when properly grounded. These desiccators offer stainless steel shelves, racks and plates which are common grounded to the cabinet and wire connected to hard ground. Stainless steel plates are recommended to enhance grounding and protect from abrasion when the desiccator floor is utilized as a shelf. (Static Dissipative Acrylic Material Data Sheet)
