RMP-O2 is an automatic recirculating oxygen purification system with a touch screen temperature control panel, which can provide an environment with oxygen concentration lower than 1 ppm for MTI's tube furnace. The gas purification system can replace expensive (10-6 torr) turbopump vacuum systems to achieve better oxygen-free conditions for crystal growth, CVD furnaces, and Ti alloy annealing furnace, etc.SPECIFICATIONS: Working Voltage 20V 50/60Hz, Single Phase (110V version is available at extra cost) 1500W Max. Purification System Precision oxygen is built-in ( without humidity sensor ) Automatically purging function is built-in for quick reducing O2 < 100ppm before recycling. The automatic pressure control system is built in to keep the pressure at a constant level. Purification Cylinder: made of BASF antioxidant materials and UOP water adsorbent materials. Purification ratings: O2 < 1ppm ( H2O < 1 ppm will reach
