Lamtec Gas Ignitors

LAMTEC America’s all-in-one design in gas igniter solutions are the industry-leading solution to cost-effective replacement of legacy equipment in terms of installed cost and operational improvements.

Igniters that consistently light off main burners, provide reliable transition support, and have proven, tested to compliance, service life, are absolutely must-haves for fossil power (boilers and HRSGs) generation competing against renewables. Igniters that ignite and support fired heater burners thus eliminating a significant source of nuisance trips drop savings directly to the bottom line.

For SIL 3 flame monitoring device F130I:



Pilot burners are necessary to secure ignition of main burners in the application of industry furnaces and combustion plants. The GFI model series in its standard design will be delivered with an integrated ignition transformer, ionisation electrode and ionisation flame scanner (both SIL 2 certified and EC type approved).

GFI models in their standard version, are approved for intermittent operation. The SIL3 flame scanner and protection class IP 65, this basic version can be applied almost anywhere.

The integrated components as well as material selection allow for use as a pilot burner. Through the application of SIL 3 flame monitoring, operator‘s requirements with regards to a modern, up to date safety technology can be met.
