Personalization

OTF-1500X-UL series furnace are UL/TUVstandard split-able mullite tube furnaces with SiC heating elements. The furnace can be installed with 2", 3" and 4" O.D high-quality mullite 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 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- 2015
Note#2:  New safety feature: An interlock system has been integrated into the furnace structure since June.2015

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 inner to increase furnace life.
  • Two pairs of 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)
  • Split cover with Interlock protectioncut the power if door open during 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 mullite tube 
  • Note: if using alumina tube: Heating rate: 10°C /min Max. and  cooling rate < 5 °C /min Max.
  • S-Type thermal couple included
  • 16 pcs SiC rod as heating elements  (1500 grade )  Pls click pic left to order spare or replacement
  • Notice:Customer will install SiC rod on site by themselves as instruction manual due to they are easy to damage during shipping.
  • Please notice, For 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)( click Pic blow for temp. Profile )
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
  • 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 3504 Temperature Controller which is fully compatible with LabVIEW. This package includes a Eurotherm 3504 programmer, a communication cable (RS485 - USB) and a software CD. Click the pic below to view the full spec of Eurotherm 3504 temperature controller.    
Vacuum sealing
  • One pair of stainless steel vacuum flange is included in the package.
  • Two pairs of 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)
  • For fast & better vacuum, suggest you use stainless steel pipe ( click to order at extra cost ) 
  • You may order pressure control module ( click picture below-right ) to keep chamber at constant pressure
                   
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 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. 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.

Notes
Operation Instructions
Warning

Click here to learn more about the installation of a gas regulator.
  • The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI 
  • Attention: A pressure regulator must be installed on your input gas tank ( click the picture below to review ) and have the gas output pressure set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition. Gas build up with pressure levels exceeding over 3 PSI may cause irreversible damage to the furnace chamber.  
  • 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.
  • The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
  • Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
  • NOTE The mullite tube shall be considered as a consumable part. We strongly recommend user keep spare tubes to ensure the continuity of operation. The tube is not covered by Warranty. Use the link to order more. 
Attention Notes
  • Performance degradation (i.e. furnace can not reach the maximum temperature 1500°C, or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen. Please order the replacements from the standard package list in below.
