OTF-1500X-II is a split two-zone tube furnace with a alumina tube and conventional flange working up to 1500°C. Two 30 segments of temperature controllers are installed with S-type thermal couples and +/ - 1°C accuracy. It is an excellent furnace for exchanging processing tubes for multi-purpose. SPECIFICATIONS: Power Input 6KW Working Voltage 208V - 240V AC Single-phase 50/60Hz ( 40 A breaker required) Working Temperature 1500°C Max. for a short time1400°C Continuously Recommend Heating rate 5°C/min. Processing Tube Alumina Ceramic Tube: 80 O.D x 74 I.D x 1000 L, mm (Pic.1) Optional mullite tube at extra cost: 80 O.D x 73 I.D x 1000 L, mm Stainless steel vacuum sealing flange with valve and meter is included. The thermal blocks are included. You may order flange support to avoid tube rotating (Pic.2) Pic.1 Pic.2 Pic.3 Heat Zone Length Two heating zones: 200 mm/ each (including 20 mm spacing) Total zone length: 390 mm Constant Temperature Zone length: 200mm (if set 2 zones at the same temperature) +/- 2ºC. Accept processing tubes up to 100 mm in diameter Temp. Profile at 1400ºC (click to enlarge) 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). RS485 Communications Port. Optional: The furnace may be operated by a PC by installing a control module. Please order an MTS02 control module at extra cost. If you order the PC control module together with 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.

The tube furnaces with mullite tubes are designed for use under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI. Vacuum pressures may only be safely used up to 1300°C. The flow rate for gases should be limited to < 200 SCCM for reducing thermal shock to the tube. Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn about the installation of a gas regulator. Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages. Compliance CE Certified NRTL or CSA certification is available upon request at extra cost.
