Horizontal Tube Furnace

Kejia series horizontal tube furnace is designed for heat treatment of all types of new materials under air, vacuum or other gases condition. There are Rotary tube furnace, Vertical tube furnae, RTP tube furnace, high temperature high pressure furnace, multi-position tube furnace and sliding tube furnace for your choose. Our tube furnace can realize 1-7 heating zone.
It can be customized according to your needs.


Kejia horizontal tube furnace uses high purity alumina or quartz tube as tube furnace, which can achieve the rapid rise and cooling while heating the samples in air, vacuum or protection atmosphere, and the temperature field is more uniform, horizontal structure design makes gas emissions more smoothly. It is widely used for materials or chemical lab to sinter and anneal materials or semiconductor wafers under vacuum or other gases condition. The furnace is controlled by an intelligent temperature controller with accuracy +/-1°C and 30 programmable segments

Standard Features

  • 1200°C,1400°C,1600°C maximum operating temperature.
  • Double layer steel casing.
  • Two cooling fans are built inside to keep temperature of outside case < 60ºC.
  • High purity alumina fibrous insulation for max energy saving.
  • Two foam ceramic thermal blocks are included, which must be placed inside tube at two ends to block heat radiation.
  • PID automatic control via current limiting phase angle fired the resistor, e.g. SCR(Silicon Controlled Rectifier).
  • Power control with 30 or 50 segments programmable.
