:: TWO STAGE HEAVY OIL BURNERS ::

The PRESS N series of burners covers a firing range from 85 to 1140 kW and they have been designed for use in civil installations of average dimensions, like building areas and large apartment groups or for use in industrial applications, like small or medium plants.

Operation is two stage; a servomotor adjust automatically air damper opening, to obtain the right air delivery on both stage. The burners are fitted with a microprocessor control panel which supplies indication of operation and diagnosis of fault cause.

The combustion head, that can be set on the basis of required output, allows optimal performance ensuring good combustion and reducing fuel consumption and is available in two different length to be selected on the basis of specific application requirements.

In basic version the burners are supplied for use with heavy oil 7°E viscosity, but they can be supplied with higher viscosity oil with a specific heaters kit. Simplified maintenance is achieved by the slide bar system, which allows easy access to all of the essential components of the combustion head.

:: MODULATING HEAVY OIL BURNERS ::

The PRESS P/N series of burners cover a firing range from 400 to 5130 kW. Operation can be “two stage progressive” or, alternatively, “modulating” with the installation of a PID logic regulator and respective probes, which gaurantees a turn down ratio of 3:1.

The versatility of this range makes the burner well suited for use on steam boilers where the load factor is subject to wide variations, on diathermic oil boilers and on boilers for particular heating plants, as hospitals or similar.

In basic version the burners are supplied for use with heavy oil 7°E viscosity, but they can be supplied with higher viscosity oil with a specific heaters kit. Simplified maintenance is achieved by the Riello designed slide bar system, which allows easy access to all of the essential components of the combustion head.

:: TWO STAGE HEAVY OIL BURNERS ::

The RN series of burners covers a firing range from 114 to 1481 kW, and has 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, which supplies Information about burner working. All necessary components of hydraulic heavy-oil circuit are assembled in a separate structure, called BAG, for easy and fast installation.

Optimisation of sound emissions is guaranteed by the use of fans with forward curved 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.
