Self-aspirating gas fired igniters
Tube Ø48.3 mm
Self-aspirating gas fired igniters guarantee the reliable and safe ignition of main burners in furnaces and boilers if no air supply lines are available. SMITSVONK gas igniters of size Ø48.3 mm can be equipped with up to four additional gas tubes for increased heat release.
The design is insensitive to moisture as the initial ignition is based on the proven high energy ignition technology of SMITSVONK. Integrated long-lasting spark plugs and ionisation electrodes assure a long service life with a minimum of downtime for maintenance.
The intake of combustion air is easily adjusted at all models. If needed the conversion to a forced-air gas fired igniter is possible with little effort.
