Please email for lead time
Item Number: OTF-1100X-R-15-AF
Transported by LTL Freight (Truck)
OTF-1100X-R-15-AF  is a large rotating tube furnace with 15" ID quartz tube with three heating zones and an automatic powder-delivering mechanism  It is designed for syntheses of the inorganic compound with better uniformity at high temperatures up to 1100ºC and 30 L powder.  It can be used to produce battery cathode or Anode power by CVD coating in large-scale production 
Furnace Construction  

  • Splittable Tube furnace with electric opening/closing function
  • SiC heating element for easy repair and replacing
  • Three heating Zone with total 1000mm(40") heating zone length
  • High-purity alumina fibrous insulation structure for maximum energy-saving
  • Gear-driven tube rotation allows "blending" type processing for powders to achieve the best processing uniformity. 
  • Automatic powder feeding and receiving systems are included
  • 15" I.D quartz tube selectable for larger-scale production.
Heating Zone length &
Constant temperature Zone

  • Three heating zones, each zone 330mm ( 13" ) long
  • Total heating zone length: 1000mm (40'')
  • constant temperature zone: 600mm at the center (with +/-5°C) ( if setting all three zones have the same heating temperature )
  • Two foam ceramic blocks with alumina coating are included which are connected to flanges and rotate together with the tube.
Working Voltage and Power
  • 208 - 240V AC three phases, 50/60 Hz
  • 45KW Max
 Powder Feeding & Receiving

  • The processing tube is evacuated to create a vacuum and thus the powder inside the feeder (under atmospheric pressure) will be sucked into the tube due to the pressure difference. A vacuum pump is necessary for such an operation. Please click the image below to order.
  • The furnace can be tilted at a certain degree to allow the powder collection on one side. 
     Quartz Tube
  • High-purity quartz tube, maximum operating temperature: 1100°C
  • Quartz tube size: 400mm OD x 390mm ID x 1800mm L
  • Two alumina blocks are included to keep powder within the heating zone
  • The inside tube is welded with stirring blades to make the powder sintering more fully and evenly.
  • Max. Loading: ~ 30 Liter Powder
     Sealing Flanges
  • The sealing flanges are provided with the processing tube. The standard configuration is:
  • The rotating seal is a magnetic fluid seal to guarantee that the front end of the flange does not move when the tube rotates under a controlled atmosphere.
Temperature Controller
  • Three 30 segments programmable PID digital temperature controller (click the left pic to see detail specs )
  • The RS485 communication port is built-in
  • Note: To achieve full temperature computerization please order a set of MTS-02 control modules. If you order the control module with the furnace we will install and test it before we ship out the product. We recommend you order the computer (laptop) from us.
