KJ-1100X-III is a three-zone tube furnace that has passed CE certification and is manufactured using UL standards. The tube furnace is equipped with an 8.5-inch quartz tube and a water-cooled flange.
|Quartz tube size||Use high purity quartz tube
Size: 216 O.D x 206 I.D x 1300mm L (8.5" O.D x 8.1" I.D x 51" L)
Warning: Quartz tube is fragile, please keep it properly. Man-made damage is not covered by the warranty.
Two alumina fiber pipe plugs are provided as standard, which are used to block the heat radiation in the pipe (the pipe plug must be placed in the heating furnace when it is working)
Optional quartz tube plug to improve cleanliness and vacuum
|Heating zone||Total heating zone length: 900 mm (36")
Three zones: 300 mm + 300 mm + 300mm (12" each heating zone)
Length of constant temperature zone: 750 mm (The same temperature can be set for three temperature zones, with an error of +/- 2°C) Note: Due to the influence of the measurement method and the external environment, the measurement result may be deviated. This parameter is for reference only. As the technical indicators of the equipment. You need accurate constant temperature zone data to purchase products, please contact our salesmanager.
|Operating temperature||Maximum working temperature 1150°C
Continuous work: 200~1100°C
Maximum heating/cooling rate: 10°C/min
|Temperature control||Equipped with a touch screen to control the temperature
Three heating zones can be set up 30 sections of temperature rise and fall programs
Temperature control accuracy +/- 1°C
Each temperature zone is equipped with a K-type omega original thermocouple
|Vacuum pump system||A digital molecular pump system is equipped under the furnace
The highest vacuum degree can reach 10-5 torr
The vacuum pump is controlled by the touch screen
|Vacuum system and flange||Equipped with a pair of water-cooled sealing flanges (hinge flanges)
The left flange is equipped with: vacuum gauge and solenoid valve controlled by touch screen (used to control the atmosphere in the furnace)
The right flange is equipped with: KF40 vacuum interface, used to connect the solenoid valve on the vacuum pump interface
The outer end of the flange is equipped with a thermocouple socket with an outer diameter of 1/4" to facilitate temperature calibration
The bottom of the furnace is equipped with a 16L/min water cooler for water supply to the water-cooled flange
|Optional||Can be equipped with gas mixing system for CVD experiment|
|Rated voltage||Single phase, 220V AC, 50/60 Hz
Including AWG 8# power cord
|Maximum power||12KW (need 50A air switch)|
|Product Size||L 1700×W 750 × H1800mm|
|Warranty||One-year warranty period, lifetime maintenance (except furnace tube, sealing ring, heating element consumable parts)|
|Quality Certification||CE certification|
|Precautions for use||The air pressure in the furnace tube cannot be higher than 0.02MPa
Due to the high internal pressure of the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when passing gas into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The pressure reducing valve range of our company is 0.01MPa-0.1MPa. Time will be more precise and safe
When the temperature of the furnace body is higher than 1000℃, the furnace tube must not be in a vacuum state. The air pressure in the furnace tube must be equal to the atmospheric pressure and be kept at normal pressure.
The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heated quartz tube
Long-term use temperature of quartz tube <1100℃
For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
