Ultrasonic Spray Pyrolysis Furnace w/ 4" Tube & Spray Nozzle and Powder Feeder



KJ-1200X-VT is Two Heating Zone Split Vertical Tube Furnace with vacuum sealed 100mm diameter quartz tube. It can introduce gas flow or liquid/ water atomization to the heating furnace, also be used for PVD, CSS or CVD coating.

Specific Introduction:
    KJ-1200X-VT is Two Heating Zone Split Vertical Tube Furnace with vacuum sealed 100mm diameter quartz tube. It can introduce gas flow or liquid/ water atomization to the heating furnace,  also be used for PVD, CSS or CVD coating. Two precision temperature controllers provide 30 segments heating and cooling program with +/- 1°C accuracy independently. The vertical tube furnace is installed in a heavy-duty mobile cart for easy moving.
Furnace Structure
  • Two Heating Zone Split Vertical Tube Furnace for longer and uniform constanttemperature zone
  • The ultrasonic spray nozzle can make liquid/water atomized via gravity and low-pressure compressed air.
  • Volumetric Feeder for feeding solid powder into a furnace to form core/ shell structure 
  • If you need a horizontal furnace, we will change to the same specification tube furnace at no cost.
  • You could upgrade from 40KHz to 3 KW and 120 KHz,  Ultrasonic Spray Nozzle at extra cost.
Power for Furnace 6KW (total) / each zone: 3KW
Voltage AC 208-240V Single Phase, 50/60 Hz
Max. Temperature 1200°C (<1 hr) each zone
Continuous Temperature 1100°C for each zone
Max. Heating Rate <= 20°C/min.
Temperature Accuracy +/- 1°C

Tube Size and Materials
  • One 1000mm length quartz tube is included
  • OD: 100 mm, ID. 95 mm
  • Foam ceramic blocks with alumina coating are included, which is hanged on top of flange to protect O-ring damaged by heat radiation
  • Upgrade note:( Processing tube can be replaced by mullite tube from 60 mm OD to 100 mm OD at extra cost, then furnace can be used up to 1250°C )

Heating Zone Length
  • 200mm ( bottom )
  • 200mm ( top )
  • 400mm ( total )
Constant Temperature Zone
  • Constant temperature zone: 300 mm (+/-1°C) if two heating zones are at the same temperature

Temperature Controller
  • MET certified 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Built in PID Auto-Tune function with overheating & broken thermocouple broken protection.
  • Over temperature protection and alarm allows for operation without attendant(s).
  • RS485 Communication Port.
Vacuum Sealing Flange
Two stainless steel flanges with vacuum gauge and valves included
A hook ring is welded inside the top flange for hanging thermal block or crucible by wireYou may choose any connectors (KF25D adapter, 1/4'' Swagelok Tube Fitting) as shown in the picture left at extra cost.

Application Note Customers may calibrate temperature before use to obtain accurate temperature inside tube furnace
  • The tube furnaces with quartz tube are designed for using under vacuum and low pressure <0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200ml/min) for reducing thermal shocks to the tube.
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
