Modulating Dual Fuel Burner
The GI/EMME 1400-4500 series of burners covers a firing range from 407 to 4650 kW. They have been designed for high output users and they are suitable for matching with all kinds of boilers, with normal or pressurized combustion chamber. Operation can be two stage progressive or, alternatively, modulating with the installation of a PID logic regulator and probes. Two operating options, gas or light oil, are available at the touch of a switch. The light oil circuit comes with its own electric motor: so the pump is stopped during gas operation to prevent pump seizure and to avoid oil in circulation. A wide range of accessories and gas trains guarantee maximum working flexibility.
