Suntec energy systems presents a wide range of oil burners from riello bruciatori, italy.

They have twin nozzle two stage firing operation as standard, the combustion air is controlled by a three position hydraulic ram which allows the air damper to fully close when the burner is at rest.

Rl/m series burners can perform as progressive two stage operation or by the addition of temperature or pressure probes, as fully modulating.
