Furnace Structure

• 
       •  Double layer steel case with two cooling fans which ensure low surface temperature
•      •  YSZ fibrous insulation is used as internal refractory
•      •  High purity fibrous alumina insulation is used as external refractory
•      •  Included vacuum flange with 30 mm quartz window. The laser beam can penetrate the furnace
           through the window and sapphire thermal block.

       •  15 KW max (75A air breaker required )
•      •  8 KW for normal working temperature
  
  

Max. Temperature

• 
       •  Each zone: 1800 °C max. (< 2 hours )
•      •   1750°C continuous

Normal Heating/Cooling Rate

Heating Zone Length

• 
       •   Three zones: total length:  610 mm  （ Z1 & Z3 = 195  Z2 = 220 mm )
•      •  Constant temperature zone:   300 mm ( if set up three zone at 1600°C )

Tube Size & Vacuum Flange

• 
       •  99.8% purity Alumina Tube
•      •  60 OD x 54 ID x 1200mm L
•      •  60 mm stainless steel  water cooling vacuum sealing flange with valve and meter is included
  
  
•          º  special quick clamp flanges for easy installation
•          º  30mm Dia x 3 mm double side polished single crystal window installed on the flange,
              which allow laser beam go through the tube
•          º  In order to block heating radiation and make laser bean transparent,  Two sapphire
              rods with two end polished must be placed inside furnace ( please order separately )
•          º  16L/min water chiller is required for cooling flange, please click picture -right to order
               separately
  
  

                 

   

• 
       •  Three digital controller via SCR (Silicon Controlled Rectifier) power control with phase angle
           fired,
•      •  Each controller is 30 programmable segments for precise control of heating rate, cooling rate
          and dwell time.
•      •  Built in PID Auto-Tune function with overheating & broken thermocouple protection.
•      •  Over temperature protection and alarm allows for operation without attendant(s).
•      •  +/- 1 ºC temperature accuracy.
•      •  Three B-type thermocouples (one for each zone).
•      •  RS485 Communications Port.
  
  

• 
       •  1 heating channel
•      •  1 programs of 8 or 24 segment
•      •  Alarm Relay: Form 'A' and Form ‘C’ built-in
•      •  Digital Communications: RS485
•      •  Temperature Accuracy:  ±  0.1ºC
•      •  Recipes: Using a PC tool recipes can be created that can be used to change the operating
          parameters of the 3000 simply by selecting a new recipe via the HMI. This is very useful
          where multiple products are processed using the same controller but require different
          parameters to be set.
  
  

• 
       •  A 10 feet length 8-3 AWG heavy duty UL approved power cable is included
•      •  Extra length cable can be ordered by click picture left
•      •  The plug is not included, but you can order from your local hardware store according to
          female plug in your lab

• 
       •  The tube furnaces with alumina tube are designed for using under vacuum and low pressure
          < 0.02 Mpa / 0.2 Bar/ 3 PSI
•      •  Never use graphite crucible in alumina 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. 
       Click here to learn the installation of a gas regulator. 
  
•      •  The gas flow rate should be limited to < 200 SCCM ( or 200ml/min )
•      •  Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely
          used up to 1500°C
