Personalization

OTF-1200X-UL furnace is configurated to meet UL/CSA certificate standard. The furnace can adopt a 60, 70, 80 or 100mm O.D quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge allow heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high precision digital controller which provides 30 programmable segments with +/- 1°C accuracy. The max. working temperature is 1200°C

SPECIFICATIONS:
Furnace Structure

  • Double layer steel casing with air cooling keeps furnace surface temperature lower than 60°C.  
  • High purity fibrous alumina insulation for maximum energy saving.
  • The special refractory coating on liner and heating element to increase furnace life.
  • Split cover with Interlock protectioncut the power if door open during furnace heating process.
Voltage and Power Input voltage 208 - 240VAC Single Phase, 50/60Hz
3KW, Circuit breaker 20A

Heating Temperature
  • Fe-Cr-Al Alloy doped by Mo
  • Max. heating temperature: 1200°C (N2 or other inert gas must be filled inside the tube to resist deformation)
  • Continuously heating temperature: 1100°C
  • Heating rate: 20°C /min Ma
  • Thermal Couples: K type 220mm (8.7") Length with Ceramic Sheath, please click the link to order spare.
Heating Zone
  • Total heating zone length: 440mm (~ 18")
  • Constant temperature zone: 150mm (+/1°C)
  • Please click the image below to view the temperature distribution at 980°C.

Temperature Controller

  • FA-YD518P-AG temperature controller is 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
  • MET Certified
Temperature controller (optional)

  • MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package is available at the options bar. Click for the detail information about the MTS02-Y software kit. 
  • You may upgrade the temperature controller to the Eurotherm 3204 Temperature Controller which is fully compatible with LabVIEW. This package includes a Eurotherm 3204 programmer, a communication cable (RS485 - USB) and a software CD.

Refractory Blocks
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • Quartz blocks (optional) are ideal for cleaner processing environment and higher vacuum efficiency.
  • You may order flange support to avoid tube rotating ( click Pic below right )
    

Vacuum Flange



  • One pair of SS 304 vacuum flange is included
  • Left flange:
    • one thermal feedthrough (for 1/4O.D sheathed thermocouple)
    • one needle valve
    • one mechanical vacuum gauge -0.1Mpa to 0.15Mpa
    • one barb fitting ( click PiC, below left-2 for detail)
  • Right flange:
    • one KF-25 vacuum port
    • one needle valve.
                 
Note: The standard vacuum flange for 70mm O.D tube doesn't have a KF-25 port or thermocouple feedthrough. Click there to see detail pic.  

Optional
An anti-Corrosive gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr is optional. Aside from greater measurement precision, this gauge reduces risks of chamber explosions
 caused by the incorrect reading of gas pressures due to gas-type dependency.

Vacuum Pressure
  • 10E-2 torr by quality mechanical vacuum pump 
  • 10E-5 torr by the turbo molecular pump.
  • The vacuum pump is optional. Please click here to choose a vacuum pump.

Application Notes


Click here to learn the installation of a gas regulator
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks 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 the installation of a gas regulator.
  • Heating module is consumable.  Please click picture below-right to order a replacement.
  • The furnace with Sliding flange is available
