OTF-1500X-III- is a split three-zone tube furnace with mullite tube and conventional flange working up to 1500°C. Three 30 segments temperature controllers are installed with S type thermal couples and +/ - 1°C accuracy. It is an excellent furnace for exchanging processing tube for multi-purpose. Note: New safety feature: An interlock system has been integrated into the furnace structure since June. 2015SPECIFICATIONS: Power Input 9KW Working Voltage AC220V Single-phase 50/60Hz ( 50 A breaker required) Max. Working Temperature 1500°C < 1 hours Continuously Working Temperature 1400°C Recommend Heating rate 5°C/min Processing Tube Tube material: Alumina TubeSize: 80 OD × 74 ID × 1200 L mmOptional tube material: Mullite tubeSize: 82 O.D x 73 I.D x 1200mm L Heat Zone Length Three heating zones: 200 mm / each (Included 20 mm spacing) Total heating zone length: 600 mm Constant Temperature Zone length: 350mm (If set 3 zone at same temperature) +/- 2ºC. Accept processing tube up to 100 mm diameter Temp. Profile at 1450ºC84mm O.D Tube (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. Three S-type thermocouples (one for each zone). RS485 Communications Port. Optional: The furnace may be operated by PC by installing a control module. Please order an MTS-02 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 to order a computer laptop from us to avoid software installation problems. For more information please click here. European Temperature Controllers (optional upgrade) 1 heating channel 1 program of 8 or 24 segment Alarm Relay: Form 'A' and Form ‘C’ built-in Digital Communications: RS485 Temperature Accuracy: ± 0.1ºC Recipes: Using a PC tool recipes can be created that can be used to change the operating parameters of the 3000 simply by selecting a new recipe via the HMI. This is very useful where multiple products are processed using the same controller but require different parameters to be set. Laptop, software & WiFi Control(Optional) Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) Labview Based Temperature Control System (MTS01)enables the user to edit temperature profiles, manage heat-treatment recipes, record and plot data for MTI furnaces. A wireless remote control provides up to 300 meters of operating range. The above features are available upon request at an extra cost (up to $1,000). Vacuum Level 10E-2 torr by quality mechanical vacuum pump 10-5 torr by molecular pump Thermal Block Placement Two thermal blacks are included.

Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min ) Vacuum pressures may only be safely used up to 1300°C for all mullite tube furnaces: Customized long heating zone up to 1200 mm L with 700 mm uniform temperature zone ( +/- 5°C) , and 1800mm mullite tube is available upon request; ( click the picture below to see sketch) 5 zones 6 zones Compliance CE Certified NRTL (UL61010) or CSA certification is available upon request at extra cost.
