1500°C Two Zone Split Tube Furnace with Flange & Mullite Tube ( 84 mm) - OTF-1500X-II


In stock
Item Number: OTF-1500X-II
Transported by LTL Freight (Truck)
OTF-1500X-II is a split two-zone tube furnace with mullite tube and conventional flange working up to 1500°C. Two 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.2015

Application Notes

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. Vacuum pressures may only be safely used up to 1300°C. The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min) for reducing thermal shock to the tube.
  • Never use graphite crucible in alumina 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.
  • 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.


Warranty
  • One year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.).  
  • ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of MTI One Year Limited Warranty.


Compliance
  • CE Certified
  • All electric components ( >24V) are UL / MET / CSA certified
  • The furnace is ready to  pass TUV(UL61010) or CSA certification at extra cost. ( please click marks below to learn details )
