1700C Single Zone High Temperature Tube Furnace

PRODUCT DESCRIPTION 1700C Single Zone Alumina Tube Furnace with 3 Channel Gas Mixer   Product Overview for 1700C CVD Tube Furnace 1700C series Gas controlled CVD tube furnace features intergrate two or three gas channels, mixed gas controlled system, high alumina ceramic tube with SS304 sealing flanges, heated by MoSi2 rods, Tmax 1700 degree C (1500C under high vacuum level). Microprocessor-based self-tuning PID provides excellent control with no overshooting and +/- 1 °C accuracy. Max vacuum level could be reached to 10E-3 torr with molecular vacuum pump.  Main Features Tmax 1700 °C Electric heated, single heating zones, high temperature, vacuum tube furnace Dual steel structure, non-Split furnace chamber to protect minium heat loss Multiple atmosphere processes in a single cycle are available Max Vacuum level achieve 10E-3 torr worked with molecular pump Fiber-insulated chamber with powerful MoSi2 heating elemets ensure uniform temperature ensure uniform temperature Shimaden PID temperature controller with programmable 30 segments SS304 vacuum sealing flanges with valves and pressure meter included Dual flanges support provides better sealing and longer tube life Long life type B thermocouple CE certified, standard Ramping, Dwelling, Cooling Curves for 1700 Series Tube Furnaces Safety Measures Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting. Overheat protection shuts down the tube furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions Power failure protection resumes furnace operation right after the point of failure when power is reestablished Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot   Technical Specifications   Model No. PTC D80/600/17 Heating zone TWO heating length 300mm Uniform temp zone: 120mm Power supply 4KW AC208-240V, 50/60Hz, single phase Working temperature Tmax 1700°C (3092°F) Continuously 1600°C (2912°F) Temperature uniformity +/- 5C Temperature controller 30 programmable segments for heating, cooling and dwelling. Built-in PID Auto-Tune function with overheating & broken thermocouple protection. Over-temperature protection and alarm allow for operation without attendant(s). +/- 1 ºC temperature accuracy.
