D-HG 400-51 high energy igniter with push-button

D-HG 400
High energy ignition device

High energy ignition device with 90 J/s for direct and reliable ignition of gas and liquid fuels.


Functionality: Thyristor-controlled capacitor discharge, microcontroller-monitored ignition

  • Technology and design proven over more than 30 years
  • Ignition power 90 J/s
  • Microcontroller-monitored ignition
  • Sustained short circuit-proof and electronic protection in the event of a defective ignition tip
  • Relay contact for ignition feedback
  • Optional retraction unit for retracting the ignition tip from the hot area
  • Reliable and safe ignition: High ignition power for direct ignition of gas and prepared oil

  • Cost savings due to wear-free igniter (thyristor-controlled)
  • Flexible system design: Exchangeable electronics module for compact and separate design and standardized ignition lances, ignition tips and high voltage cables
  • Certified for the applications ATEX, IECEx, Ex d IIC and Ex de IIC

  • Coal-fired power plants with oil pilot burners: Reliable direct ignition with well-prepared oil (steam-atomized)
  • Marine: Ignition of auxiliary and special boilers on ships using gas and/or oil as fuel
  • Refineries: Use in potentially explosive atmospheres for ignition of gas, oil or other liquid fuels
  • Technical data
  • Explosion protection
