They are designed for combustion of Biogas only and of Biogas and an alternative fuel ; combustion of the two fuels is alternately and not contemporary and the fuel change need the burner re-start. The Low NOx combustion head allow to comply the emission requirement of operating standard with both fuels Biogas and Methane natural gas. Operation is modulating with the installation of a PID logic regulator and respective probes. The RS 25÷200/E-EV burners are equipped with a Digital Burner Management System, which can manage the air-fuel ratio by independent servomotors, based on a specific adjustment curve per each fuel, and allows both, local and remote gas selection . The RS /EV models are available to operate with the motor speed variation technology based on the control of a Frequency Inverter, in order to optimize the energy consumption. All the models are equipped with UV flame sensor and the burners for dual fuel are also equipped with a double max pressure switch (based on power output) to assure a safe operation on all modulation range.
