Large Vacuum Drying Oven



Large scale vacuum drying oven designed for treatment of large-sized parts

Performance and functions

  • Vacuum pump can be installed inside the oven
  • Quick connect / disconnect of vacuum pipes for easy vacuum pump maintenance
  • Because the exhaust system is improved to significantly shorten the time to reach vacuum, working efficiency is improved.
  • Use specialized function menu key and ▲▼ key to set. With program operation function, use submenu key to operate overheat protector, deviation correction, etc.

Safety features

  • Self-diagnostic functions (abnormal temperature sensor, heater disconnection, auto overheat prevention, SSR short circuit), overheat protector, ELB to prevent overcurrent, key lock, etc.
  • For safety, resin protection panel is installed at the observation window
