Detailed
Specific Introduction:
    KJ-1200X-4-C4 is a special dual-tube CVD system designed for coating thin film on the metal foil, especially for preparing flexible electrode on metallic foil on new generation energy research. Fast heating and cooling can be achieved by sliding the furnace. Please refer to the Operations Instructions section to see the operations of the furnace:

  • A dual quartz tube:100mm Dia. exterior tube and suspended by 80 mm Dia. interior tube. Metallic foil (Graphene Growth Substrate) will be wrapped around the inside the tube surface for CVD reaction. 
  • The flanges for the dual tube, which allow reactive gasses to flow between two tubes ( 10mm space ) and the inert gas flow inside the tube for cooling.
  • 4 gas channels controlled by 4 separate digital MFCs
  • The vacuum pump is included with KF25 adapter and pipe for plug and play
  • Sliding rail is installed on the bottom of the furnace, which allows for fast heating or cooling by sliding furnace from one side to the other side.
  • One slide stopping clamp is included for holding the position of the furnace.
Both the heating zone and vacuum system are selectable: Single or dual heating zone; High-Speed Oilless Dry Vacuum Pump - VBS-M1 or Two-Stage Mechanical Pump - VBS-ACP15.

Vacuum Flanges
Using dual-tube for inducing CVD growth on metal foil (wrapped around interior tube surface):
  • 1-1. Shown below, one pair of SS304 flanges to seal both the outside tube and space between the outside tube and inside the tube (this space is considered as a reaction chamber).
    • Left side flange: Barb fitting with needle valve as gas inlet, a digital vacuum gauge with measuring range 10^-4 to 1000 torr, water cooling inlet/outlet included
    • Right side flange: Right angle valve with KF25 flange fitting, a vacuum release needle valve, water cooling inlet/outlet included
  • 1-2. Leave both ends of the inside tube open for gas cooling.

Vacuum Pump Station and valves
 
  • Optional 1:
  • Pfeiffer's High Speed (226L/min) Oilless Dry Vacuum Pump, 10E-3 Torr Limit is installed inside a heavy-duty mobile cart.
  • KFD25 adapter and stainless steel pipe are connected between the pump and tube flange with a precision ball valve.
  • 10E-2 Torr vacuum can be achieved inside the processing tube
  • A digital vacuum gauge is installed on the left side flange.

  • For vacuum level to 10^-5 torr, please order below mobile turbopump
 
Water Cooling Function
 
  • Water cooling on the flange is mainly for cooling down the o-ring inside the flange to ensure the best-sealed chamber at high temperature:
  • Water cooling flanges require >= 10L/M water flow.
  • You may use tap water as the coolant, but we strongly suggest you use a recirculating water chiller for environmental considerations.
Optional Parts (building up a single tube furnace)
  • You can build up an 80mm Dia. single tube reaction by ordering extra sealing flanges and install them onto the interior tube:
  • Left side flange: Barb fitting with needle valve as gas inlet and 1/4'' feedthrough fitting for the customer to insert a measuring sensor (e.x. an insertable thermocouple for temperature calibration)
  • Right side flange: KF25 fitting with mechanical gauge and vacuum release valve
Dimension
  • Furnace: 550 x 380 x 520mm
  • Bottom mobile case x 2: 600 x 600 x 600mm (one for gas mixing station and the other for vacuum pump)
