The new RL BLU series represents Riello’s last step of innovation in terms of Low NOx technology applied to light oil burners.

The series includes three models, with an output rangingrom 116 to 598 kW. Those burners have been e-designed

for use in hot or superheated water boilers, hot air, steam generators or diathermic oil boilers.

A servomotor with three adjustable positions guarantees correct air output and air damper closing when the burner is turned off. The burners are fitted with a microprocessorbased control panel, which supplies indication of burner status and fault causes.

A new, more compact and handable case has been designed, keeping overall dimensions compact in order to ensure an easier servicing and maintenance.

The elevated performance of the forward-blades fan, together with a new innovative combustion head, guarantee flexibility of use and excellent working at all firing rates always with Low NOx emissions.

Guidelines for installation of burners in conformity to EU Regulation:

A RIELLO burner (Heat Generator), where it is matched with a water-based boiler (Heater Housing) with a nominal output ≤ 400 kW, providing heat for heating purposes and heat to deliver sanitary hot water, can be installed:

- With boilers (heater housings) already in service in the field, for replacement of identical products, in conformity to Article 1, paragraph 2, point (G) of the EU Regulation No. 813/2013;

- With boilers (heater housings) on a new installation, if they have emissions complying with the requirement of Annex II, paragraph 4 of the EU regulation No. 813/2013.
