D-HG 5x0-51 high energy igniter with push-button

D-HG 500
High energy ignition device

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.

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

  • 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
  • Coal-fired power plants with oil pilot burners
  • 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
