Automatic regeneration process may be completed in as little as 13 hours and while unattended
Cylinder contains 5 pounds of copper catalyst capable of removing up to 5 liters of oxygen (13,5000 ppm) and 5 pounds of molecular sieve capable of removing 660 grams of moisture (18 million ppm) with normal oxygen and moisture permeation rates 0.3 ppm/min or lower.
Fully factory-regenerated cylinder is ready to use. Isolation valves arrive closed to maintain molecular sieve and copper catalyst capacity.
From a 1000 ppm starting condition, able to reduce oxygen to 1 ppm in less than 2 hours.
From a 1000 ppm starting condition, able to reduce moisture below 15 ppm in 2 hours, below 10 ppm in 6 hours, below 5 ppm in 16 hours, below 2-3 ppm in 2 days and as low as 1 ppm in 3-6 days.
System automatically compensates for power outages and starts the regeneration process over if interrupted for 10 minutes or longer. This feature ensures complete regeneration of the copper catalyst and molecular sieve since proper regeneration cannot occur if the system has cooled.
Factory leak-tested with a mass spectrometer while pressurized with helium at 5 inches of water gauge. No detectable leaks greater than 1 x 10-6 ml/sec.
Internal stainless steel gas purification lines have oxygen and moisture permeation below 0.1 ppm/min.
Achieved less than 1.67 ppm/minute oxygen permeation when using test methods at -4 inches of water gauge on Protector Fiberglass and Stainless Steel and Precise Conrolled Atmosphere Glove Boxes. Lowest attainable oxygen levels are 0.2 ppm for stainless steel, 0.4 ppm for fiberglass, and 3.5 ppm for polyethylene. Lowest attainable moisture levels are 1 ppm for stainless steel, 2 ppm for fiberglass and 5 ppm for moisture.
Vacuum pump outlet is rated at 115 volts, 6 amps or 230 volts, 4.5 amps.
Three microprocessor-controlled solenoid valves, located on the back, for connection to 4% hydrogen/inert gas mixture, vacuum pump and vent exhaust.
Communications port, located on the back, allows for shared access to the vacuum pump with the glove box.
