ValuLine Extended Storage Desiccators provide the strength and durability of Terra’s other desiccator lines for long-term storage requirements that don’t demand frequent parts access. These cabinets are also ideal for general-purpose storage applications where recovering a low-humidity condition after opening a door is not critical.

  • Reinforced doors and rigid cabinet construction ensure a long service life
  • Select economical acrylic of static-dissipative PVC for electro-static protection and enhanced particle control
  • Adjustable-height acrylic or electropolished stainless steel shelves (order separately) accommodate a variety of sample sizes
  • Easy-clean rounded corners makes these cabinets ideal for particle-sensitive applications
  • Flowmeter and Automatic RB® (Relief/Bleed) valve allow nitrogen purging for dry storage requirements (order separately)
  • Also ideal for use with desiccant or as a general-purpose dust-free storage cabinet
  • Select Terra’s ValuLine or Adjust-A-Shelf™ Desiccators for rapid low-RH recovery in applications that require frequent access to parts

Terra’s ValuLine Extended (ES) Storage Desiccators combine low cost and strength for operations that don’t require rapid recovery of critical low-humidity setpoints. Add the optional Smart control module (order information below) for automatic RH set-point maintenance.

Designed for use with a nitrogen purge, a desiccant, or simply for clean storage, these cabinets feature heavy-duty chrome-plated hinges and reinforced doors with closed-cell gaskets for a long, reliable service life. Expansion latches provide a positive seal without internal scraping caused by rotary-style latches. The closing mechanism is positioned outside the cabinet to keep stored materials clean.

Economical acrylic models provide strength and full visibility of stored parts. For applications that require wipe-down with alcohol or other strong cleaning agents, choose chemical-resistant static-dissipative PVC, which also protects stored samples against electro-static discharge (ESD). By safely removing surface charges, it also eliminates particle attractions and enhances cleanliness.

All models include chrome-plated wire racks for shelf positioning. Select desired shelves, flowmeter, automatic Relief/Bleed (RB) Valve, and stand separately.


Automatic RB (Relief/Bleed) Valve 
Relieves excess pressure; require for nitrogen purging.
1-10 SCFH

Order desired shelves separately:
SS-reinforced plastic (top), electropolished 304 SS perforated (center) or electropolished SS solid (bottom)

Shelves and Tray
Acrylic shelves feature stainless steel front and back reinforcements to prevent bowing. Solid or perforated electropolished 304 stainless steel shelves are sealed in plastic before shipping to minimize contamination.Trays can be used for storage within the desiccator, and are a convenient way to carry parts after they are removed.

Powder-Coated Stand
Raise cabinets 4″. Noncontaminating nylon leveling feet included. Select optional casters below. Recommended for cabinets with more than three chambers to allow floor positioning.

Hunidity Module

Smart Relative Humidity Control Module
Can be retrofitted into any cabinet above to convert a ValuLIne ES Desiccator into aValuLine SmartDesiccator, capable of controlling a nitrogen purge to maintain a user-selected %RH setpoint.Refer to User Guide document no. 1788-07 for detailed retro-fit instructions.
