Personalization

OTF-1700X-UL series are UL/TUV standard split-able alumina tube furnaces with MoSi2 Heating Elements. The furnace can accomodate 60 or 80mm O.D high-quality alumina tubes along with a pair of smart stainless steel vacuum sealing flanges that features needle valves and vacuum gauge. Such configuration allows sample heat treatment under vacuum or flowing gas conditions up to 1700°C. The precise temperature controller can provide 30 segments of heating and cooling with +/- 1°C accuracy.

Furnace Structure
 
  • Splitable Design provides easy access to the tube replacement
  • Double layer steel casing with air cooling to ensure a low surface temperature < 60°C.  
  • High purity fibrous alumina insulation for Max. energy saving.
  • The special refractory coating on the furnace liner and heating element to increase furnace life.
  • Two sets of fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)

 208 - 240VAC SINGLE PHASE, 50/60Hz
Power
 7 KW (40A Breaker)
Heating Temperatures
  • Max. heating temperature: 1700°C, < 10 minutes (N2 or other inert gas must be filled inside the tube to resist deformation)
  • Continuously working temperature: 1500°C (1600°C < 1hr)
  • Heating rate: 10°C /min Max.
Heating Zone
  • Total heating zone length: 400mm
  • Constant temperature zone: 140mm (+/-1°C)
Heating Elements
  • 16 pcs MoSi2 1800 grade Heating Element.
Temperature Controller

Temperature controller interface


Optional PC control module


Optional Eurotherm 3204 
Standard temperature controller:
  • 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 (PC control module and software are sold separately. See optional.

Optional:  
  • MTS-02 PC control module (also including cable and software) is an add-on option for PC control.
    • It is recommended to purchase the module together with the furnace. We install and test it before shipping. 
    • It is recommended to purchase the laptop (with software pre-installed) from us to avoid software confliction.
    • Please note the module is not sold solely in the future.
  • Eurotherm 3204 Temperature Controller is optional for additional $950 including installation and testing. This package also includes the communication cable (RS485 - USB) and software CD. Click here to view the full spec.
Vacuum Sealing
  • Two stainless steel flanges with vacuum gauge and valves. 1/4" pipe  and KF25 adaptersare installed in two ends respectively.
  • For fast & better vacuum, suggest you use stainless steel pipe ( click to order at extra cost ) , as well as digital vacuum gauge. 
  •  Two pairs of fiberous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
                            
    Vacuum Levels

    Application Notes
    Warnings

    Click here to learn more about the installation of a gas regulator

    • NEVER open the furnace lid at temperature >100°C, doing so may thermoshock the processing tube and cause cracks. 
    • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
    • Never use graphite crucible in alumina tube.
    • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the-the pressure to below 3 PSI for safe operation. Click here to learn 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 unforseeable damages.
    • .The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
    • Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
