OTF-1500X-UL series furnaces are split-able alumina tube furnaces with SiC heating elements. The furnace can be installed with 2"or 3" O.D high-quality alumina tubes along with a pair of smart stainless steel vacuum sealing flanges that can take either a valve/gauge which allows for heating samples under vacuum or flowing gas conditions up to 1500°C. The precision temperature controller can provide 30 segments of heating and cooling steps with +/- 1°C accuracy. Note#1: Updated from GSL-1500X-OTF with UL standard components and Vertical SiC rod since 6-24- 2015Note#2: New safety feature: An interlock system has been integrated into the furnace structure since June.2015SPECIFICATIONS Optional OTF-1500X-UL-2 OTF-1500X-UL-3 Alumina Tube Size 50 OD x 40 ID x 1000 L, mm Click the link above to order a spare tube 76 OD x 67 ID x 1000m L, mm Click the link above to order a spare tube Furnace Structure Double-layer steel casing with air cooling to keep furnace surface temperature lower than 60°C. High-purity fibrous alumina insulation for Max. Energy-saving. The special refractory coating on the inner increases furnace life. Two pairs of fibrous ceramic tube blocks are included to block heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) Split cover with Interlock protection, cut the power if the door opens during the furnace heating process. Input voltage 208 - 240VAC SINGLE PHASE, 50/60Hz Power 6.0 KW （40A Breaker Required） Heating temperature Max. heating temperature: 1500°C (< 1hr) Continuously heating temperature: 1400°C Heating rate 10°C /min Max. and cooling rate < 10 °C /min Max. for alumina tube Note: if using alumina tube: Heating rate: 10°C /min Max. and cooling rate < 5 °C /min Max. The S-type thermal couple is included. 16 pcs SiC rod as heating elements (1500 grade) Pls click pic left to order spare or replacement Notice： Customers will install SiC rods on-site by themselves as instruction manual because they are easy to damage during shipping. Please notice, for the SIC heating element, it is a consumable part, and not covered by warranty, and usually, its service life is one year. Heating zone &Constant Temperature Zone Total heating zone length: 390mm Constant temperature zone: 150 mm (+/-2°C) Temperature Controller FA-YD518P-AG temperature controller included. Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed with ramping, cooling, and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm +/- 1 ºC temperature control accuracy Default DB9 / PC communication port Vacuum Sealing One pair of stainless steel vacuum flange is included in the package. Two pairs of fibrous ceramic tube blocks are included to block heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) For a fast & better vacuum, suggest you use stainless steel pipe ( click to order at extra cost ) Vacuum level 10^-2 torr by a mechanical vacuum pump.10^-5 torr by Turbomolecular pump.Leak rate < 5 mtorr / min. Pressure Measurement / Monitoring Standard mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa. OPTIONAL: A gas-type independent (above 10 mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces the risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency. Laptop, software (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, and record and plot data for MTI furnaces. Compliance CE Certified NRTL(UL61010) or CSA certification is available at extra cost. Notes Please click here to see our typical temperature profile calibration result at various temperatures. How to set up a ceramic tube and vacuum flange for MTI Tube furnace Proper placement of tube blocks The furnace can grow 3C-SiC film on Si; please read the below article to see the procedure Warning Click here to learn more about the installation of a gas regulator. The tube furnaces with alumina tubes are designed for use under vacuum and low pressure
