Specific Introduction:
KJ-1500X-6Z is a six-zone split tube furnace with alumina tube and vacuum-sealed flange working up to 1500°C. Six 30 segments temperature controllers are installed with S type thermal couples and +/ - 1°C accuracy. It is an excellent furnace for high-temperature CVD and annealing application
Parameters:

Working Temperature	Max. temperature： 1500°C ≤30 minutes Continuoustemperature: 800 -1400°C
Recommend Heating rate	5°C/min.
Processing Tube	Material: Alumina Size: 60 O.D x 51 I.D x 1800mm L Other specifications available upon request
Heat Zone Length	Six heating zones: 12" +8" + 8" + 8" + 8" + 12" Total heating zone length: 1422 mm ( ~ 56") Constant Temperature Zone: 800 mm +/- 5ºC. ( If set 6 zones at the same temperature, without zone spacer. If you don't need the zone spacer, you shall inform us in advance) The Built-in heating zone space to create a thermal gradient up to 100ºC/ cm
Temperature Controllers	6 digital temperature controllers for controlling each heating zone PID automatic control with 30 programmable segments for precise control of heating rate, 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 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. For more information please .
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.
Vacuum Level	10E-2 torr by quality mechanical vacuum pump 10-5 torr by molecular pump
Thermal Block Placement	Two thermal blacks are included. Please click the picture below to learn how to place them inside tube You may order flange support to avoid tube rotating
Heating Elements & Thermal couples	48 pcs 1500ºC grade Silicon carbide rod (14mm Dia. x 150mm heating x 413mm length) The heating element is consumable, Six S-type thermocouples (one for each zone).
Application Notes	The tube furnaces with mullite tube are designed for use under vacuum and low pressure < 0.02 Mpa Never use graphite crucible and the 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. The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min ) Vacuum pressures may only be safely used up to 1300°C for all mullite tube furnaces: Customized long heating zone up to 1200 mm L with 700 mm uniform temperature zone ( ± 5°C) ，1800mm mullite tube is available upon request;
Warranty	One year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products page).
