Why Choose A TDI Desiccator?

#1 IN CUSTOMER SATISFACTION FOR 25+ YEARS

TDI Acrylic Desiccators provide the highest quality and most durable construction to meet the requirements for cleanroom and assembly component storage applications.

TDI desiccator storage cabinets are designed for in-line nitrogen or clean dry air (CDA) source to assure adequate gas pressures (PSI - source to desiccator) and adequate gas volume for continued humidity control operation of the desiccator.

SUPERIOR GRADE MATERIALS & INNOVATIVE DESIGN

Acrylic Material Construction for Cleanroom/ESD Applications
All TDI desiccators utilize 1/4" acrylic or static dissipative acrylic, an inherently inert and clean material (non out-gassing).  Competitive brands are often constructed using less expensive 3/16" polyvinyl chloride (PVC), polypropylene or polycarbonate materials with plasticizers present, which can contaminate cabinet contents.

Nitro-Save® Humidity Control Monitor
Controls Pre-Set Relative Humidity ±2%
Reduces Nitrogen Consumption up to 90% (20%RH) In Many Applications
Conditions May Vary by Application
Retro-Fit Kits Available for Existing Desiccators!

The primary purpose of desiccators is to establish precise relative humidity levels to protect moisture sensitive materials in a clean environment.  

TDI has developed an economic, solid state system that accurately controls humidity and reduces nitrogen consumption.  Competitive desiccator brands offer expensive moisture control systems that are dependent on electro mechanical switches to control moisture flow.  These systems are subject to maintenance with repair/replacement in the long run with compromised reliability.  Ironically, most desiccators in service have no RH% moisture control and often consume excess nitrogen to compensate.

TDI Static Dissipative Acrylic Desiccators cannot be tribocharged when properly grounded.  Stainless steel plates in desiccators enhance grounding and protect from abrasion when cabinet floor is utilized as a shelf.

Ultra Nitro-Flow Compartment Flow Through System
All TDI acrylic desiccators are constructed with Ultra Nitro-Flow compartment flow-throughs, which achieve a single pressure condition throughout the cabinet.  This unique design allows maximum flow in both the vertical and horizontal directions and reduces higher moisture humidity conditions between compartments.

CNC Fabrication for Precise Design and Manufacture
All TDI desiccators are CNC machined to assure precision accuracy and reproducibility to TDI's design criteria.

Cabinet Door Design / Seal Integrity
All TDI desiccators include unique cabinet door design for minimum door weight with maximum seal integrity and durability.

• 1/4" Acrylic doors with bow design stiffeners insure uniform sealing.
• Closed cell neoprene, non out-gassing gasket material is recess mounted into CNC pre-machined slots to insure integrity in placement.
• Spring loaded latches provide air-tight door seals.
• Electropolished stainless steel continuous door hinge for maximum door support.

TDI's composite doors, gaskets, latches and hinges superior design features insure maximum air-tight sealing of our desiccators, while eliminating the need for expensive stainless steel door frames.

Although the doors are often the first failure point of a desiccator, TDI's composite design features have proven virtually indestructible in our 25 years of providing desiccator cabinets to our customers worldwide.

Typical competitive brands with thinner plastic door material, rubber gaskets mounted to the door and refrigerator style latches require heavy and expensive stainless steel door frames to achieve adequate sealing.

Removable Plenum Chamber for Uniform Nitrogen Gas Flow
The static dissipative plenum chamber includes removable static dissipative acrylic back wall for easy access and maintenance in humidity control monitor applications.  
The Nitro-Save® solenoid valve is mounted in the plenum chamber to regulate the nitrogen flow in response to the high humidity set point.

Highest Quality + Lowest Cost + Total Technical Service = Best in the Industry!
