SERIES CODE: TF

High vacuum tube furnace with Φ240mm×L350mm working zone and far-infrared heating.

TF1000-250HV
Thumbnail 1
The TF1000-250HV high vacuum tube furnace utilizes far-infrared heating, with high-purity quartz tubes (dehydroxylated). This equipment consists of a vacuum system, heating element, electrical control system, and water cooling system. It is primarily suitable for vacuum annealing processes of semiconductor devices, vacuum brazing, vacuum degassing, refining and heat treatment of metallic materials, and annealing and shaping of nickel-titanium materials in the medical industry.
