1 TWO STAGE DUAL FUEL BURNERS RLS SERIES 1/ kw 116/ kw RLS 5 145/ kw RLS 7 232/ kw RLS 1 349/ kw RLS / kw The RLS series of burners covers a firing range from 1 to 1395 kw, and they have been designed for use in hot or superheater water boilers, hot air or steam generators, diathermic oil boilers. Operation is "two stage"; the burners are fitted with an electronic device LED PANEL, that, in every moment, shows burner operational modes. Optimisation of sound emissions is guaranteed by the use of fans with forward inclined blades and sound deadening material incorporated in the air suction circuit. The elevated performance of the fans and combustion head guarantee flexibility of use and excellent working at all firing rates. The exclusive design ensures reduced dimensions, simple use and maintenance. A wide range of accessories guarantees elevated working flexibility.
