D-HG 500


High energy ignition device with max. 112 J/s for direct and reliable ignition of gas and liquid fuels. The ignition frequency and duration are variable.


  • 25% more ignition energy than the D-HG 400
  • Ignition power 112 J/s
  • Ignition frequency adjustable on site
  • 1 … 20 sparks/s
  • Modern electronic design: Microcontroller-monitored ignition, sustained short-circuit-proof, electronic protection in the event of a defective ignition tip
  • Wide temperature range: -40 … +80 °C
  • Relay contacts for ignition feedback and ignition readiness
  • 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, standardized ignition lances, ignition tips and high-voltage cables
  • Certified for the applications ATEX, IECEx, Ex d IIC and Ex de IIC
