Closed Loop Gas Circulation Inert gas in a closed loop. The gas is circulated by the blower and purifier, H2O, O2 can be removed continuously. Auto Purging The replacement of the atmosphere inside the glove box can be achieved automatically by the purging valves. Automatic Regeneration H2O and O2 removal material can be regenerated. The regeneration process can be program controlled. Automatic Pressure Control The pressure in the glove box is controlled automatically by the Programmable Logic Controller (PLC). Working pressure can be set between +10mba and -10mba. If the pressure goes over+/- 12mbar, the system will be protected automatically. Eco Mode The vacuum pump will be activated automatically when necessary, and will turn off after a period of idle time. Blower frequency will be switched to 25Hz when moisture and oxygen level reaches to less than 1 ppm Main Chamber Dimensions Modular length: 1220mm/1500mm/1800mm/2440mm ( 48.0”/59.1”/70.9”/ 96.0”) Modular depth: 750mm/1000mm/1200mm (29.5”/39.4”/47.2”) Modular height: 900m( 35.4”) Material: Stainless steel type 304, thickness 3mm (1/8”) Sight Windows: Inclined, Safety Glass, thickness 8mm (1/3”) Gloves Ports: POM (Polyoxymethylene), 220mm (8.7”) Diameter Gloves: 8B1532 Dust Filter: HEPA 0.3μ, one gas inlet, one gas outlet Shelving: Stainless Steel, two fixed shelves (adjustable shelves available) Lighting: External fluorescent lamp, front mounted above sight glass.
