Product Overview

Vacuum heat treatment furnace features a sealing chamber with high alumina content fiber insulation and powerful heating elements up to 1600 degree C. We build the vacuum furnace structure with dual steel structure, welded and oil leak tested chamber to ensure air tightness. Dual door design make the chamber sealing condition much better. Max vacuum level reach to 10-5 torr with Diffusion vacuum pump unit. Multiple gas inlets and outlets with stainless steel ball valves. The vacuum furnace provides the perfect heat treatment environment for various procedures in many laboratories, providing the controlled temperature and atmosphere specific projects require.

Main Features
  • Tmax 1700°C (in air)
  • Dual steel structure, air tight chamber
  • Multiple gas inlets and outlets with stainless steel ball valves and mechnical gauge.
  • High vacuum level up to 10-5mbar
  • Water circulation device for furnace cooling
  • Powerful MoSi2 heaters heating from two sides ensure uniform temperature
  • Precise PID controller with progrmmable 30 segments
  • Long life type B thermocouple
