OTF-1700X-VT is a splitable single zone vertical tube furnace suitable for sample heating or quenching under vacuum or flowing gas conditions up to 1700°C. Single crystal growth and heat treatment system can be set up with a quenching system, lifting mechanism, or other motion mechanisms. SPECIFICATIONS: Power Input 7KW Working Voltage AC220V Single-phase 50/60Hz (40 A breaker required) Working Temperature 1700°C Max. for a short time1600°C Continuously Recommend Heating rate 0 ~ 1400 ≤10/min1400 ~1600 ≤5/min Features High-purity aluminum fiber insulation material is more energy efficient. Double layer shell with air cooling system. Stainless steel vacuum sealing flange with valve and meter is included B-type double platinum-rhodium thermocouple The thermal blocks are included. Tube size: 60 O.D x 54 I.D x 1000 mm L Heating-Zone length: 400mm Temperature Controllers PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Built-in overheating & broken thermocouple protection. Over-temperature protection and alarm allow for operation without attendant(s). +/- 1 ºC temperature accuracy. Two S-type thermocouples (one for each zone). DB9 Communications Port. Optional: The furnace may be operated by a PC by installing a control module. Please order an MTS-02 control module at extra cost. If you order the PC control module and the furnace, we will install and test it before shipping. We recommend you order a computer laptop from us to avoid software installation problems. For more information please click here.
