Dual-Side Access Pass-Through Desiccators
Dual-side access desiccators are
ideal for dual-side access.
Shown: Series 400 Stainless Steel Desiccator
  • Front and rear access doors allow pass-through operations into a cleanroom or stockroom
  • Advanced construction techniques optimize seals to maintain a positive pressure and extend shelf-life of stored materials
  • Select fool-proof stainless steel interlock mechanism to limit access to one door per chamber at any time
  • Optional stainless steel doors extend the service life of the desiccator
  • Shelves adjust on chrome-plated racks to accommodate different sizes of stored materials

These storage cabinets provide the same controlled environment as our standard Adjust-A-Shelf Desiccator, but add dual-side access versatility.

Easy Desiccator Access in Many Applications
They are easy to install in a cleanroom or stock room wall, or you can position Dual-Side Access Desiccators side-by-side in an assembly area to form a room divider that allows dual access to stored materials from both aisles.

Whatever the application, these cabinets help safeguard stored materials from damage associated with particles, moisture and static. Constructed of acrylic or Static-Dissipative PVC, they feature easy-open doors and one-piece wall construction to minimize the problem of peeling or sagging gaskets and to ensure a continuous seal. All seams are solvent-welded to eliminate the problems of outgassing, and all hardware is chrome plated or 304 stainless steel.

Completely Automatic Nitrogen and Humidity Controls
Each cabinet features an inlet to allow the introduction of nitrogen purge gas, and an outlet for easy installation of Terra's Automatic RB® (Relief/Bleed) Valve, which guards against overpressures and functions as a check valve. The optional Dual Purge™ System and NitroWatch® enhance system performance by automatically regulating the gas purge to maintain any subambient moisture level you require, down to 0% RH. A plenum chamber ensures uniform gas distribution.

Desiccator Standardization
Terra Universal has standardized its desiccator storage systems and accessories to offer you the most flexible, economical solutions available. Shelves are available in acrylic (with stainless steel bow guards) and solid or perforated 304 stainless steel.
