High energy ignition device

The SVECU ignition device is suitable for the reliable ignition of gases in pilot burners used for flares in long distances. Depending on the application and condition of the fuel also light liquid fuels can be ignited.

Available models are compatible with SMITSVONK pilot burners and are integrated in robust industrial made housings which allow an easy and durable installation.

Integrated flame detection is realized by a thermocouple relay. Specific adaptions and the installation of multiple SVECU high energy igniters for the operation of several pilot burners is projected on customer's request.


  • Reliable ignition of gaseous fuels
  • Ignition of light liquid fuels (e.g. diesel oil)
  • Perfect for flare ignition at longer distances 
  • Thyristor controlled and therefore non-wearing electronic
  • Direct control by integrated PLC




  • Chemical industry
  • Refineries
  • Waste water treatment
  • Land fill
