BWO

High energy ignition device

The BWO ignition device is suitable for the reliable ignition of gases in ignition burners and pilot burners used in furnaces, boilers and incinerators in various industries.

The electronic unit is equipped with a fail-safe ionisation flame relay which allows to connect easily to the ionisation rod of the designated ignition burner and realize the flame detection of the burner hassle-free. In addition the contact for remote start can be used for convenient operation out of the control room.

The main electronic is installed in an explosion proof housing of type Ex d while simple wiring is possible due to the terminals located in an Ex e housing. Both are industrial made and robust for long-lasting installations.

Overview

  • Ignition of gaseous or light liquid fuels
  • Suitable for ignition or pilot burners
  • Integrated flame relay for ionisation flame monitoring
  • Ready-to use contact for remote start
  • Thyristor controlled and therefore non-wearing electronic

Applications

  • Chemical industry
  • Refineries
