1200℃ Three Zones Split Tube Furnace

1200℃ Three Zones Split Tube Furnace

Model:KJ-1200X-III

Description:

KJ-1200X-III series are long, and split-able three-zone tube furnace with tubes up to 127mm (5") O.D capable of quickly heating up to 1200°C. The multiple zones also enable the user to create different thermal gradients by varying the temperature of the three zones.

Detailed
Specific Introduction:
    KJ-1200X-III series are long, and split-able three-zone tube furnace with tubes up to 127mm (5") O.D capable of quickly heating up to 1200°C. The multiple zones also enable the user to create different thermal gradients by varying the temperature of the three zones. The furnace includes one fused quartz tube, one pair of vacuum sealing flanges with pressure gauge & a ball valve for immediate use. Three 30 segments temperature controllers are installed with a K-type thermal couple. Microprocessor-based self-tuning PID control provides excellent temperature control without overshooting along with an accuracy of +/- 1 °C. It is an excellent furnace for annealing, diffusing, and sintering samples under various gas atmospheres.
Parameters:
Furnace Structure
  • Double-layer steel case with two cooling fans, which ensure low surface temperature;
  • Energy-saving high purity fibrous alumina insulation;
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating
  • Split cover with interlock protection
  • Quartz block (Optional) is ideal for more cleanness and a higher achievable vacuum.

Quartz Tube Size
OTF-1200X-80-III-UL OTF-1200X-4-III-UL OTF-1200X-5-III-UL
80ODx 72IDx 1400L mm (3.14"D x 55" ) Quartz Tube: 101 OD x 92 IDx 1400L mm (4" x 55") 130 ODx120 IDx1400L mm (5"x 55")
Warning: The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.12 MPa (absolute pressure)
Heating Zone Length 3 zones: 900mm (36") in total  
300mm  (11.8") for each zone
Temperature profile Constant Temperature Zone: 25" (625 mm) length 
(Three zones are heating at equal temperature simultaneously)
Dimensions 1030 x 430 x 580 mm  (not included flange and tube)
Rated Voltage AC 208-240V Single Phase, 50/60 Hz (40A breaker required)
The power cord is included without plug
Power Consumption 7 KW Max.
Heating Elements Fe-Cr-Al Alloy doped by Mo
Heating Temperature
  • Max. Heating Temperature: 1200°C
  • Continuous Heating Temperature: 1100°C
  • 1000°C under vacuum
  • Max. Heating Rate: 20°C/min
Temperature Controller
  • 3 digital temperature controllers certified by MET and CE Certified
  • PID automatic control with 30 programmable segments for control of heating & cooling rate and dwell time.
  • Built-in overheating & broken thermocouple protection.
  • Over-temperature protection and alarm allow for operation without attendant(s).
  • +/- 1 ºC temperature accuracy.
  • RS485 Communications Port.
  • Optional:
    • The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at an extra cost. 
    • If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us to avoid software installation problems. 
Eurotherm Temperature Controllers (optional upgrade)
  • 1 heating channel
  • 1 program 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.
Flange Fittings
 
  • One pair of SS 304 vacuum flange with double high-temperature silicone O-ring  is Included
  • 2 needle valves are installed with flange
  • One Vacuum/ pressure gauge is installed one side flange
  • The vacuum level: 10-2 torr by the mechanical vacuum pump and 10-5 torr by the turbopump.
  • Optional: You may choose flange with a KF25 vacuum port for a faster and better vacuum, and click the picture below to order a vacuum pump separately
  • You may order flange support to avoid tube rotating
Dimensions 1700 x 430 x 580 mm  
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 Contact us to order the replacement at related products.)
Compliance
 
  • CE Certified
  • NRTL (UL61010)  or CSA certification is available at extra cost. 
Shipping Dimensions 65x40x45"
Shipping Weight 385lbs

Application Notes
 
  • Attention:  A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure below 3PSI for safe operation. 
  • We suggest accommodating an FH-60 fume hood with this furnace
