Oven for Degassing UHV Power Tubes
Product Details:
The "UHV Station for Processing POWER TUBES" essentially consists of : Double walled water cooled cylindrical chambers acting as a baking hood having top closed with dished end bottom flanged and sits on water cooled base plate. Water cooled base plate with number of UHV ports where the power tubes are mounted. No. of tubular heaters are provided to heat the hot zone to 600 Degree C and each chamber is provided with seperate heaters. 3 layers of cylindrical heat shields made out of 1mm SS material are provided separately for each chamber. Water cooled heater Feedthroughs for both the chambers Heater power supply ( Thyrister controlled) with programmable PID to control the temperature for heating and soaking cycle and for a max. temperature of 6000C. K type thermocouples are provided to measure temperature at the hot zones of baking the hearth. The additional thermocouples with digital indicators are provided for job temperature measurement. Bell jar and chamber is provided with a Roots and Rotary combination to evacuate them to 10-3 mbar. Pumping line is provided with Right angle Pneumatic valve. UHV port pumping can be provided with the Turbo Pump and all metal angle valve and ion pump with UHV Gate Valve to evacuate the UHV line to 10-9 mbar. Turbo pump can be backed by a small dry pump. Multi gauge controller with suitable gauge heads can be provided for measurement of UHV port and guard vacuum. UHV lines are provided with detachable band heaters to bake the pumping lines to 3000C. All metal electro pneumatic or mains operated vent valve are provided for venting UHV port and guard vacuum. Console with PLC .
