The RDB series of one-stage light oil and kerosene burners, based on different ventilation structures, is available with output ranges from 12 to 110 kW.

The models of this series are available in versions with combustion air suction from the installation environment (conventional flue "CF") or external air intake (balanced flue "BF"); both versions can be fitted with a fuel pre-heater.

All models are characterised by their compact size and share the same components, designed by Riello exclusively for the RDB series.

RDB burners are equipped with:

• a volumetric pump designed to be used with kerosene, low-sulphur kerosene, and ultra-low sulphur light oil (ULSD). 
• a Low NOx head, capable of guaranteeing high reliability of operation and stable combustion.
• a blast tube (84mm diameter)
