Hegwein was established in 1948, and is since 1996 member of the DURAG GROUP. More info about DURAG GROUP you can find here.

Hegwein develops and designs combustion equipment. Hegwein manufactures series e.i. produced components for OEMs in the combustion business and bespoke igniters, burners and pilot burners.


Why choosing Hegwein products ?

  • Design based on a vast experience of more than 60 years
  • No moving parts (retraction) ensure low maintenance
  • Low maintenance costs and low operational costs due to high combustion efficiency
  • Highly reliable pilot flame ignition and monitoring
  • Long, stable very powerful pilot flame for absolutely reliable main burner light-off at different load conditions
  • Long service life, even under the most adverse conditions
  • Very short delivery times
  • Burners and igniters are of the "nozzle-mixing type" - No danger of internal fire, flashback or conflagration
  • Igniters have no turn-down ratio and can therefore be operated within relatively narrow limitations only.
           At first sight this seems to be a disadvantage but is in fact a decisive safety asset!

    • Compact, integrated design offers striking advantages

  • Spark transformer and flame monitor integrated into cast aluminium enclosure with small dimensions
  • Lightweight, yet sturdy construction
  • Guaranteed electromagnetic compatibility
  • No high-voltage cable laying required at site, eliminates interference problems
  • Very short commissioning times
  • Stable 90 V flame signal that can be connected to a flame relay or burner control
  • Integrated flame relay with dry SPDT contact, also available with NAMUR contact wiring
  • IP 65 and Ex-versions also available
  • Low-maintenance design
