Descriere

RS 45÷55/E BLU
The RS/E C05, BLU and RS/EV BLU burners series covers a firing range from 44 to 2400 kW, and it is based on a new Digital Burner Management System, Riello REC27-37 or Siemens LMV52, which is able to manage the air-fuel ratio by independent servomotors in order to obtain a perfect output control and to assure a correct combustion and safe operation on all modulation range. Operation can be “two stage progressive” or, alternatively, “modulating” with the installation of the dedicated probe (with burner models equipped with REC27-37 control box, an additional PID logic regulator is required). RS/E BLU burners series guarantees high efficiency levels in all the various applications, thus reducing fuel consumption and running costs; specifics versions are available to operate with Variable Speed Drive technology base on the control of a Frequency Inverter that modifies the air flow through the motor speed variation.

Optimisation of sound emissions is guaranteed by the special design of the air suction circuit and by incorporated sound proofing material. Finally, new RS/E-EV BLU burner models, equipped with Siemens LMV52 control box and compatible with combustion optimization based on the residual O2 content in the exhaust fumes, are now available.

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.
