Specific Introduction:
    KJ-1500X-II is a high-temperature two-zone splittable rotary tube furnace. It is designed for synthesizing inorganic compounds with better uniformity at an ultra-high temperature up to 1500ºC. This furnace can be upgraded to 1600ºC Max. with Kathal 1650 grade SiC heating elements.
Furnace Feature
  • Two-zone heating for longer constant temperature zone
  • Double shell casing with three cooling fans.
  • 1500ºC grade or 1650 grade SiC heating element.
  • High purity alumina fibrous insulation for max. energy saving.
  • The split cover enables faster cooling and easy operation.
Voltage 208 - 240V single phase (40 A Breaker required)
Power 6 KW Max
Furnace Tilt Angle -5 - 35°
Tube Rotating Speed 0 - 7 RPM variable
Production Yields 2 kg per batch
Max. Vacuum level 4.5x10-2 torr (<0.1mtorr/s leaking rate if close all the valves to airtight the tube chamber)

Heating Zone Length
  • Two heating zones: 195 mm for each zone, total  390 mm length
  • Constant temperature zone: 250 mm within +/-5oC. ( if two zones at the same temperature )
Heating Elements &
Working Temperature
  • 16 pcs 1500ºC grade silicon carbide rod (14mm Dia. x 150mm heating  x  420mm length)
  • The rods are considered consumables and won't be covered by the warranty.
    • 1400°C Max for continuous heating.
    • 1500°C Max for < 1 hour of heating.
Temperature Controller &

  • Two 30 segments programmable PID digital temperature controller 
  • Two built-in S type thermocouple
Processing Tube & Sealing
  • One Alumina processing tube with central block zone: 60mm OD x 54mm ID x 1200mm L with a max. the working temperature of 1500ºC is included.
  • One pair of 60mm SS sealing flange with needle valves and rotatable gas connector is included            
Gas Fitting
  • Inlet Fitting: Elbow push-in connector for 6mm O.D tube
  • Outlet Fitting: Elbow push-in connector for 12mm O.D tube
Continuous Powder Feeding & Retrieving System

  • The automatic powder feeder is mounted on the feeding system support via a feeding swivel coupling with pressure gauge.
  • Feed rate adjustable by the potentiometer knob, 97cm^3/min max.
  • One stainless steel tank is installed on the other end of the processing tube to gather the fired powder without exposure to air.
  • One Alumina processing tube (60mm OD x 54mm ID x 1200mm L) with gear is required.
Warranty One year limited warranty with lifetime support (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
  • NRTL (UL61010)  or CSA certification is available at extra cost. 
Product Net Weight 200Kg
Shipping Weight & Dimensions 675 lbs; 53" x 40" x 77" 
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.
  • For CVD coating, you may choose our multi-channel Gas delivery system
  • The tube furnaces  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 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
