Humidity Control Chambers
Full Humidity Control
These units allow the user to control interior humidity levels above or below ambient conditions. All units are equipped with the latest in Humidity Sensor technology and Ultra Sonic Humidifier and either Desiccant Drying System or a Dry Gas Purge System.
STYLES Two standard styles available, a clear Polycarbonate unit that features a lower cost to purchase, and relatively low cost to customize. The Aluminum units while more expensive on initial purchase are a longer lasting, sturdy build that with the addition of tempered Glass can be used in highly corrosive chemical use. Polycarbonate units have 4 standard sizes and Aluminum units have two.
AUTOMATIC CONTROL The automatic controller provides monitoring and control of the relative humidity. It activates the necessary system (dehumidification for humidification) when the moisture level deviates from the adjustable set point. Flow rates, sensor position circulation, and orifice positions were all considered in the design to maximize control capabilities and humidity uniformity across the glove box. Since this is a closed loop circulation system, an inert gas environment can be maintained in the glove box while controlling the humidity.
HUMIDIFIER The Ultra Sonic Humidifier vibrates the water in the reservoir to provide a cloud of mist that is pushed into the glove box from the pump system. At the same time air is pulled out of the glove box and circulated through the water reservoir, completing the Humidification System’s closed loop circuit. Water reservoir is equiped with Self Sealing Quick Disconnect inlet for refilling under sealed conditions.
DRYING SYSTEMS Two systems are available to dry these Humidity Control Glove Boxes a Desiccant Drying System (Pictured above) and a Dry Gas Purge System. The Desiccant System is standard however the Dry Gas Purge System can be substituted at no extra cost. The Dry Gas Purge System allows for a lower attainable humidity level 3% (1% using special dry gas) vs 5% for the desiccant System. The Gas Purge System is also cleaner, provides faster drying times and requires less maintenance (Desiccant needs to be rejuvenated). The Desiccant Drying system can be a lot less expensive to operate. The two systems can also be used to work together to minimize the cost of the dry gas purge system.
GLOVELESS SLEEVE All units are equipped with gloveless sleeves to allow superior handling of interior samples. However the moisture from skin does influence Humidity levels below 15% Rh and for these applications the user may need to operate with gloves which can easily placed over COY over the gloveless sleeve cuff.

TRANSFER CHAMBER OPTION All units have an optional pass thru chamber (air lock) available. This enables transfer of equipment and samples with out drastic changes to the interior environment.
