Detailed
Specific Introduction:
    KJ-1700X-HV furnace consists of a high-temperature alumina tube furnace and a high vacuum system.
It can be heated up to1700°C by a different type of MoSi2 heating elements and achieve vacuum pressure up to 10^-4torr with a diaphragm pump. It is widely used for material or chemical lab to sinter all types of new material samples under vacuum or other gas conditions. The temperature of KJ-1700X tube furnace is controlled by 30 segments programmable high precision SCR power controller with accuracy +/-1°C.

Heating element 1700 grade MoSi2 
Working Temperature 1700°C (2912°F) Max.  <1hr
1600°C continuously
Normal Working Temperature 800 -1700°C (2732°F)
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 protection.
Over-temperature protection and alarm allow for operation without attendant(s).
+/- 1 ºC temperature accuracy.
RS485 Communications Port.

  • Advanced Temperature Control (Optional)

High Vacuum Station Structure Mobile cart size:  600 (L) x 600 (W) x 700(H), mm
Max. Loading:       600 Lbs on top
Molecular pump control Panel:   LCD digital
Inside:   Pfeiffer vacuum pump 
Vacuum sensor is included
Vacuum sensor Two vacuum gauges are installed in this system.
1. Mechanical vacuum gauge
2. High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar) is installed in the whole high vacuum system for monitoring the high vacuum status when operating the furnace with HV station support.
Control Panel One button operation - the diaphragm pump and the turbomolecular pump will start after pressing the "start" button.
System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber.
Self-protection - the system will protect the pump from damage by overheating and over-current if the leaking rate of the reaction chamber is too high to achieve a high vacuum.
LCD screen - double lines parameters checking interface make the working easier to be handled.

Warranty One year limited warranty (Consumable parts such as processing tubes, o-rings, and heating elements are not covered by the warranty, please contact us to order the replacement.)
Compliance
  • CE Certified
  • All electric components ( >24V) are UL / MET / CSA certified
  • The furnace is ready to pass TUV(UL61010) or CSA certification at extra cost. 
Note
  • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
  • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. 
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
  • The flow rate for gases 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
