In stock
Item Number: OTF-1200X-5L-R-III-UL
Transported by LTL Freight (Truck)

The OTF-1200X-5L-R-III-UL is a 5" rotary CVD tube furnace with three heating zones built in the NRTL standard. The furnace is especially good for preparing Li-Ion battery cathode and Anode  materials with conductive coating, such as LiFePO3, LiMnNiO3, Si/C etc. This rotary furnace has larger tube diameter (5"OD) combined with a longer and more uniform heating area (three zones, 900mm overall length

Furnace Construction
  • Double shell casing with three cooling fans
  • High purity Alumina fibrous insulation for max. energy efficiency
  • DC Gear motor drives quartz tube with variable speed 0 - 10 RPM
  • The furnace can be electrically tilted up to 30° .
  • Split cover enable faster cooling and easy operation.
  • All electric components are UL or Met recognized and ready to pass any safety test worldwide
Heating Zone length
  • Three zones: (600mm, 24" in total)
    • Zone 1: 150 mm  
    • Zone 2: 300mm  
    • Zone 3: 150 mm 
  • Constant temperature zone: 450 mm within +/-2ºC if two zones are at same temperature.
Processing tube & Flange
  • Fused quartz tube (one is included)
  • Dimension:  130 mm O.D. x 120 mm I.D. x 1200 mm L + 60 OD mm (two ends )

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.

  • Ref Article: Scalable synthesis of silicon-nanolayer-embedded graphite for high-energy lithium-ion batteries
  • The tube furnaces with quartz tube are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
  • 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 limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
