Item Number: OTF-1200X-S-R-II
Transported by LTL Freight (Truck)
OTF-1200X-S-R-II is a compact two zones rotary tube furnace with 2" quartz tube, designed for calcining inorganic compound with better uniformity, especially good for preparing Li-Ion battery cathode powders with conductive coatings。
Furnace Construction

  •  Double shell casing with three cooling fans
  • High purity Alumina fibrous insulation for max. energy saving
  • Gear DC motor drives quartz tube with variable speed 0 - 5 RPM
  • Split cover enables faster cooling and easy operation
    Compact size  for space saving. 

Heating Zone length

  • Two zones: each zone length 4" (100 mm), total 8" (200 mm) heating zone
  • Constant temperature zone: 100 mm within +/-2oC if two zones at the same temperature.

Application Notes
  • The concept of continuous power feeding and processing can be realized by the use of Magnetic Fluid Sealed Swivel Coupling in line with Volumetric Feeder and Rotary Furnace. Please view the assembling approach diagram and video in below.         
  • For CVD coating, you may choose our multi-channel Gas delivery system and automatic feeding system  as Pic below 
Operation Video
  • The tube furnaces with quartz tube are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 Mpa
  • 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.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
