Please email for lead time
Item Number: OTF-1200X-6M
Transported by Flatbed Truck
OTF-1200X-6M  is a 12-Zone & 20 Feet Long  5“0D  split tube furnace with separated temperature control units and max working temperature of 1100oC. This 12 -zone furnace  18' long constant heating zone by setting all the temperature controllers at the same temperature. The furnace can accept processing tubes up to 5" .   Touch Screen precision temperature controllers are built in a separate control box which allows PC control of the furnace from a certain distance. It is an excellent furnace to treat long strip samples under a vacuum and controlled atmosphere. 
Furnace Structure

  • Double-layer steel case
  • High-purity fibrous alumina insulation provides good energy savings.
  • Heating Element: 1300 °C grade Fe-Cr-Al Alloy doped by Mo
  • Modulated chamber, which allows the ultra-long to furnace easy shipping and installing

 Application Notes

  • Tube furnaces with quartz/mullite tube are designed for use under vacuum and low pressure <0.2 bar
  • Attention: A two-stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  •  Vacuum pressures may only be safely used up to 1500°C
