    Specific Introduction:
        KJ-1200X-S-II-R 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

    Processing Tube
    2"  Fused quartz processing tube with mixing blade in the center
    Gas Fittings
    • Inlet Fitting: Elbow Push-in connector for 6mm O.D tube; Outlet Fitting:  Elbow Push-in connector for 12mm O.D tube
    • Option parts: If do not want plastic connector, please upgrade to Inline Swivel Head
    Max. Working Temperature 1100°C for continuously   1200 °C Max for < 2 hours
    Temperature Control
    • Two PID digital temperature controller with 30 segment programmable,  +/- 1°C
    • Each heating zone's temperature  is controlled independently
    • Two Omega K type 3mm OD x 6" L with high-temperature tolerance (220°C) connector

    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 below
    For CVD coating, you may choose our multi-channel Gas delivery system and automatic feeding system
    • 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.
    • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
