Inert Oven

DN411IE/611IE

Description

Inert ovens suitable for temperature test and heat treatment in a non-oxidizing environment, by introducing N₂ gas into the chamber

Performance and functions

  • Heat resistance test and heat treatment of up to 360°C
  • Simple operation by interactive key input
  • Standard equipped with various operation modes such as program operation and calibration offset function, power failure recovery mode selection, and user configuration information saving
  • Repeatable operation function up to maximum 99 steps, 99 patterns controller with repeat function
  • N₂ gas flow amount controllable

Safety features

  • Enhanced safety countermeasure, including self-diagnostic functions,  digital  setting,  independent  overheat  prevention device and electric leakage breaker
  • In case of door opening during operation, fan and heater turn OFF by door switch
