Provided with Progressive and Modulating operations, the dual fuel burners series NOVANTA represents the max achievement of our experience on medium-large burners, the range runs from 480 kW to 4100 kW. Like all other dual fuel models they combine all mechanisms to work with two different fuels separately. This is possible because of a separated circuit for the oil pump motor; it means that the oil pump motor is not running when burner is working on natural gas.
They are equipped with a high performance combustion head designed to achieve the max efficiency when working on natural gas; combustion head is also equipped with a by-passing nozzle which, using a pressure regulator, can reach a turndown ratio 1:3.
The control panel facia is printed with a mimic diagram fitted with neon lamps to indicate the different stages of the burner operation. The burner is provided by an UV photocell to detect the flame during operation. 

Burners "VS" series are equipped with multiple firing heads in order to achieve a shorter flame.

Unlike other burners available on the market today, these burners have been designed with four combustion heads to produce a "soft " and compact flame , whereby the thermal energy contained in the flame is better distributed throughout the combustion chamber.

This feature allows the use of the burner in very short combustion chamber boilers.

Each system can be further distinguished by the equipment provided:
