THREE ZONE ALUMINA TUBE FURNACE Three Zone Alumina Tube Furnace with Vacuum Flanges is a CE certified 60mm OD three zones tube furnace with complete vacuum sealing flange. Each heating zone is 12" in length and controlled by three precision 30 segments digital temperature controllers independently.

One zone (centre zone) is heated by Super-1800 MoSi2 elements up to 1700째C, and another two zones are heated by SiC elements up to 1400째C. The tube furnace can create various thermal gradient by adjust three zones temperature. It is excellent furnace to prepare functional materials under thermal gradient, and also can be used for epitaxial film growth by CVD. Its structure is made up of Double layer steel case with two cooling fan, which ensure low surface temperature. High purity fibrous alumina insulation is for energy saving purpose.

Three heating zones are provided in the furnace. A stainless steel vacuum sealing flange with valve and meter is included. You may replace the standard barbed hose fitting with the KF25 adapter. For supplying high pressure gas, you may replace the standard barbed hose fitting with the VCR Face Seal Fitting, Three digital controllers with microprocessor-based PID control and self-tuning.

Microprocessor-based self-tuning PID control provides excellent control without overshooting and +/- 1 o C accuracy. It is an excellent furnace for annealing, diffusing and sintering sample in various atmospheres. Each has 51-segments programmable with protection for overheated and broken thermo-couple is included for immediate use.

Furnace structure Double layer steel case with two cooling fan, which ensure low surface temperature. Energy saving high purity fibrous alumina insulation. Max. 80 mm stainless steel vacuum sealing flange with valve and meter is included. Two porous ceramic blocks are included for protect flange from heating radiation. Vacuum pressure can reach to 10-4 torr with proper vacuum pump. Digital programmable control is provided with 30 segments per program. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.
