Standard Features and Options

• Control systems for maintaining stable environmental conditions
• Dual side access doors provide convenient through-put of materials and small process equipment
• Removable back panel allows large process equipment to be placed within the glove box
• Air lock chambers to isolate the glove box interior against ambient conditions when transferring materials
• Stainless steel frames that enhance sealing performance and protects the door plastic from damage, increasing overall life
• Changeable sleeve and glove combinations. Other glove types are also available

Four Outlet Power Strip:

• Provides an convenient electrical connection for process equipment being used within the clean processing environment
• Mounted horizontally on the inside rear wall 3” from the bottom work surface
• Includes a master on/off switch, 4-outlets and a 15-amp circuit breaker

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.
