Terra's complete line of desiccator cabinets provide the protection your sensitive products need from airborne contaminants, electrostatic discharge, and excessive temperature and humidity. But what about security—from fire, explosion—or unauthorized access?

The Double-Agent Desiccator Safe performs the two vital functions called for by more and more manufacturers today: clean, dry, ESD-free storage and maximum security from tampering, theft, smoke and fire.

Components such as microelectronic devices demand stringent protection against heat, humidity, ESD, and particle contamination, therefore standard safes designed to protect paper records are inadequate. Internal temperatures in these units can reach as high as 350°F, and they offer little guarantee of stable humidity, positive pressure, or contamination control. Resulting conditions may leave paper products intact, but they destroy or degrade your valuable materials and devices.

That's why we've incorporated all of the advanced features of our desiccator cabinets into this security system. The multi-door design of the inner shell minimizes exposure to inrushing contaminants, and a continuous purge of gas maintains a positive pressure. Terra's Dual Purge/NitroWatch control systems maintain the programmed RH set-point, and peform nitrogen purges only when needed.

The desiccators also features an Automatic RB® (Relief/Bleed) Valve that prevents over-pressurization and damage to the desiccator. Stainless steel perforated shelving facilitates gas flow for even distribution. Shelf racks are built in for easy placement and adjustment.

Outside, the Double-Agent Desiccator Safes function like the toughest, most tamper-proof safes available. These systems maintain safe internal levels of heat and humidity under extreme conditions—even with external temperatures as high as 1700°F! The external steel door is designed to prevent the influx if smoke or water, as well as particle-contaminated air.

The many locking features of the Double-Agent Desiccator Safes are designed to guard against unauthorized access—and to rout the most determined spy. Locking 4.25" internal drawers are positioned above the desiccator (except for model 6500-20), giving you additional space for storage of documents or small items. Use the anchor bolt to attach the safe to the floor, preventing unwanted movement (all except model 6500-22).

External doors of the Double-Agent Dessicators Safe are equipped with a keypad for entering a passcode. The door will refuse to open if three unsuccessful attempts are made. The keypad records the passcodes used to open the doors, providing traceable entry records. Safe doors lock on the top, bottom and side with chrome bolts.

Desiccator chambers are manufactured using transparent static-dissipative PVC, which protects against static charges and the particles they attract. Built-in shelf racks allow additional shelves to be installed. 

Safes without desiccator chambers are also available.
