Key Features
Dual fuel configuration supports gas firing together with light oil firing.
Air and gas mix at the blast pipe, while light oil is atomized mechanically at high pressure through a nozzle.
Combustion air and blast-pipe settings can be adjusted during commissioning to tune combustion performance.
The mixing unit and atomization unit can be removed for maintenance without removing the burner from the boiler.
Electronic proportional control uses three-phase servo motors to manage the gas, oil, and air ratio.
The hinged body opens naturally for easier inspection and service access.
Combustion air intake includes an air-flow adjustment device and a noise-reducing inlet design.
A high-temperature stainless steel flame disc is used at the burner head.
An independent motor drives the oil pump.
UV flame supervision is provided by an ultraviolet phototube.
Electrical protection rating is IP40.
