Key Features
High-pressure mechanical atomization uses a nozzle for light oil firing.
Combustion air and blast-pipe settings can be adjusted to tune combustion performance.
The atomization device can be removed directly for maintenance without removing the burner from the boiler.
Single-stage models use manual air-flow adjustment at first fire.
Two-stage models use hydraulic regulation for first-stage and second-stage air flow.
A flange and insulating sealing ring are used for boiler connection.
The combustion air inlet includes a flow-regulating device.
Sliding flanges allow the burner position to be adjusted for different boiler flanges.
The adjustable combustion head uses a steel blast tube and flame disc.
A single-phase motor drives the fan and oil pump.
Flame supervision is provided by a photoresistor.
Electrical protection rating is IP40.
