    KJ-1200X-VI is a CE certified Ready Six-zone & ultra-long split tube furnace with separated temperature control units and max working temperature of 1200oC .

    Specific Introduction:
        KJ-1200X-VI is a CE certified & UL Ready Six-zone & ultra-long split tube furnace with separated temperature control units and max working temperature of 1200oC . This six-zone furnace can create step thermal gradient or 60" ( 1500mm ) long  constant heating zone by setting all the temperature controllers at same temperature. The furnace can accept processing tube with various O.D (1" to 4") at extra cost. Six 30-segment temperature controllers are built in a separate control box which allow PC software control of the furnace from a certain distance. It is an excellent furnace to handle various gases.
    Furnace Structure
    • Double layer steel case
    • High purity fibrous alumina insulation provides good energy saving.
    • Heating Element : 1300 °C grade Fe-Cr-Al Alloy doped by Mo

    • Total zone length: 2000 mm, or 80" in total ( including seperating )
    • Max. Constant temperature zone 60" ( 1525 mm ) if 6 zones are heated to the same temperature (within +/- 2 °C)

    Temperature Controllers
    • Six PID automatic digital temperature controllers with 30 programmable segments for precise heating rate, cooling rate and dwell time control.
    • Built in overheating & broken thermocouple protection.
    • Over temperature protection and alarm are available.
    • +/- 1 ºC temperature accuracy for each controller.
    • Six K type thermocouples and one for each zone.
    • With RS485 Communication port and MTS-02 control module, operators can utilize PC to control the furnace in distance (< 5 meter)  

    Tube & Flange

    • One pair stainless steel vacuum flange is included with quick assembling flange ( a outside clamp for quick installation). Left flange with needle valve with 1/4" pipe port for gas inlet and one pressure gauge; Right flange with KF 25 port for vacuum pump connection as shown below
    • The furnace can accept quartz or mullite tube with 1" - 4" diameter  (Optional)
    Dimensions Furnace: L2800mm x W500mm x H950mm
    Temperature Controller: L700mm x W500mm x H1100 mm
    Warranty One year limited warranty for electrical parts. (Consumable parts such as processing tubes,  o-rings and heating elements are not covered by the warranty, please order the replacement at related products page.)  

    • CE Certified
    • All electric components ( >24V) are UL / MET / CSA certified
    • The furnace can pass TUV(UL61010) or CSA certification after minor modification at extra cost. Certification fee is charged separately.
    Shipping Weight & Dimension Furnace: 1250 lbs; 114"x39"x52"
    Controller: 315 lbs; 48"x40"x56" 

    • Tube furnaces with quartz/mullite tube are designed for using under vacuum and low pressure <0.2 bar/ 3 psi/ 0.02MPa
    • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. 
    • * Vacuum pressures may only be safely used up to 1500°C  
    • The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
