Burner Management Systems
The burner control unit QBK [cubic] is suitable for the control of pilot burners up to 350 kW and main burners of unlimited capacity, pursuant to EN 7462, for intermittent or continuous operation.
Flame control by means of UV scanner or ionization rod (even shared with ignition) and high temperature option for flame surveillance bypass. Specific output for air valve or fan, following cycle or independently controllable.
Times and cycle are configurable: the same device can be used to control different types of gas, oil and mixed burners. User interface providing a ledbar flame signal indicator, seven segment status display and reset / shutdown button. Remote control and supervision of the burner can be implemented by means of digital inputs/outputs or through serial communication.
The unit is integrated into an aluminum enclosure, available in 3 versions.
Fault code acquisition from a smart phone, programming from a laptop.
