Micron-Aire™ Large “Double Tier” Plastic Desiccator Cabinets / Dry Boxes

Stainless Steel Door Frames:

• Re-enforces and prevents potential damage to the plastic doors, increasing overall cabinet life
• Enhances sealing performance by securely holding a one-piece gasket material in place to virtually eliminate gasket movement or failure
• Select the appropriate part number and quantity needed for the selected dry box desiccator cabinet(s)

* Acrylic shelves should not be used with static-dissipative PVC desiccator cabinets.
Additional product information:

1. Stainless steel shields being purchased for installation on clear and amber acrylic desiccator cabinet’s, should be considered with the addition of desiccator grounding (optional). See Grounding (desiccator) option below for further information.
2. Shields are factory installed. When purchased for use with a static-dissipative PVC desiccator, the shields will be installed and connected to the system grounding, which is a standard feature on these cabinets.
3. Perforated shields, shelves and trays are available upon request (at additional charge)

Adjustable Shelf Supports:

• Reinforces the desiccators internal fixed in-place plastic shelves for accommodating heavier storage loads
• Minimizes detrimental cabinet damage caused by overloading storage chambers
• Installed below the cabinets ceiling allows convenient placement of Cleanroom Synergy’s Gas Purge™ and Gas Monitor™ Controller units
• Adjustable, Low-profile design allows placement without taking away valuable storage space
• Install in pairs for better loading capability
• Select the appropriate quantity needed for the selected desiccator cabinet(s). Install in pairs for better loading capability
• Fabricated out of 304 stainless steel

Note: It is recommended that stored materials, whenever possible, be distributed evenly though-out the storage
chamber and not centrally located in the center of the chamber as to minimize un-necessary damage to the desiccator cabinet.

• Provides desiccators with mobility for moving from workstation to workstation and for ease of cleaning around its stationary position
• Heavy-duty, low-profile set of 4 caster set, includes 2 with side brakes
• Increases the desiccator stand height from 4” (with leveling glides) to 7.5” (192mm)

Flow Meters:

• Scales are hot stamped into the front of the acrylic body and will not wear off
• Bodies are precision cut and machined from clear acrylic blocks with a smooth tapered bore that provides perfect visibility of the indicating float
• Accuracy is ±5% of full scale with a scale average 2″ long
• Features brass (stainless steel optional) inlet and outlet connections, black glass float, Buna-N O-rings and tapped for 1/8″ NPT female process connection (vertical mounting)
• Service: Compatible gases and liquids
• Includes nickel plated brass hex nipple and 90 degree elbow (female x male), 1/8” (3.18mm) pipe size for connection to Cleanroom Synergy desiccators, glove boxes or other gas purged enclosures

Auto-Adjust™ RB Valve:

• Automatically adjusts to gas flow rates and possible sudden surges
• Eliminates possible negative pressure incidents due to its one way air flow design
• Continuously bleeds off excess internal gas to maintain a safe pressure within desiccators, glove boxes and other hermetically sealed enclosures
• Includes a nickel plated brass hex nipple fitting (1/8” NPT) with a polyurethane O-ring to ensure a positive seal against the hermitically sealed enclosure
• One Auto R/B Valve per cabinet is required if desiccator is to be purged with dry gas
• Installation of one Auto-Adjust™ RB Valve in each desiccator storage chamber eliminates cross contamination and R/H fluctuation in the unopened chambers

Gas Purge™ Control System:

• Automatically activates a high-flow gas purge when a chamber door is accessed
• Protects moisture sensitive materials against oxidation, increasing product yield
• Ensures a constant positive pressure within glove boxes and other hermetically sealed enclosures to block out contamination influx
• Dramatically reduces purge gas cost when compared to systems using only a mechanical flow meter
• Adjustable electronic flow meter precisely regulates the flow rate of the purge gas
• Digital pressure regulator safely adjusts the pressure of the incoming gas
• Operates in conjunction with the optional Gas Monitor™ Control Unit to maintain desired sub-ambient moisture level (down to 0% RH)
• High-reliability door switches are rated for millions of operations. One per desiccator chamber required
• Works with120/240VAC, 50/60Hz, and requires no manual power selection

The Gas Purge™ Controller monitors and regulates the dry gas that will flow into the desiccator when it is needed to lower the R/H or
when a chamber door is opened. It has a gas regulator to control the pressure of the incoming gas and electronic flow meter that regulates
and maintains the low flow of gas. Also provides audible/visual warnings when the supply gas is getting low, a desiccator door has been left
opened or if the R/H set point has not been reached.

Gas Monitor™ Control System

• The Gas Monitor™, when used in conjunction with the Gas Purge™ Controller will automatically maintain desiccator R/H levels from ambient down to
  R/H of the purge gas (0% for most dry gases)
• Incorporates a state of the art micro-controller, a bright readable R/H display and simple control buttons
• Since the desiccator only needs gas when the R/H rises above the set point, it uses much less gas resulting in large cost savings
• Small solid state humidity sensor never needs calibration, easily installed and takes a small amount of desiccator space
• Can be used to monitor R/H levels in any enclosure without the use of the Gas Purge™ controller
• Works with120/240VAC, 50/60Hz, and requires no manual power selection

The Gas Monitor™ controller measures the R/H of the chamber which contains the Gas Sensor. It has provisions to enter a desired R/H set point and
will issue a command to the Gas Purge™ controller to lower the desiccator cabinet’s humidity level whenever it senses a reading above the R/H set point.
It also monitors the open and closed positions of the desiccator doors and issues a command to the Gas Purge™ controller to introduce dry gas at a
high flow rate while the door is opened and for a preset time after the door is closed (factory set at 60 seconds).

Sonic Humidifier™:

• Provides a stream of high humidity gas to enclosures that require higher then ambient R/H level
• Automatically generates moisture using a sonic transducer and a connected water source
• Can be used for environmental testing of a large variety of devices to determine performance in wet conditions
• Works in conjunction with the Gas Purge™ and Gas Monitor™ control systems to maintain a specific R/H set point
• Works with120/240VAC, 50/60Hz, and requires no manual power selection

For actual control of the humidity level, the Sonic Humidifier™ must be used in conjunction with the Gas Purge™ and Gas Monitor™ control systems.

Grounding (Desiccator):

• Safely discharges the operator when accessing stored material
• Helps protect sensitive materials from electro static discharge damage
• Provides interconnection of the door latch, door catch, hinges and racks with conductive tape and termination at a multi lug grounding block

Notes:

1. Charge for grounding is per desiccator chamber, therefore, quantity should correspond with the number of chambers on the affected desiccator cabinet
2. Grounding is a standard feature on all static dissipative PVC desiccator cabinets
3. A ground fault circuit interrupter should be considered to provide personnel protection

Ion Power™ Unit

• Neutralizes static charge build-up by introducing positive and negative ions into the desiccator cabinets storage chamber
• Provides electro-static-discharge of non-conductive materials, which cannot dissipative or transfer charges to ground
• Helps to neutralize electrostatic charges on interior cabinet surfaces that induce contamination influx by attracting air borne particulates
• 120/240V, 50/60Hz, requires no manual power selection
