Integrated safety system based on an inlet chute with a counterweighted hinged flap, creating a physical barrier between the combustion chamber and the fuel feeder.

The counterweighted hinged flap automatically closes the feed chute, preventing flame backflow into the fuel feeder. The technology ensures safe burner operation without requiring additional power supply — it is a mechanical system, reliable even in the event of a power failure.

REVO line variant

Solution applied in REVO, REVO EC and REVO EC HG line burners.

ECOS line variant

Solution also applied in ECOS line burners (50–250 kW) — mechanical inlet chute with a hinged flap, adapted to a larger fuel inlet.
