Features

CFK device is designed to control gas burners in accordance with norm EN 746-2, for
intermittent or continuous operation. Different versions are available and many parameters are
configurable to have the best solution for every plant.

Applications

Available in BASIC or FULL version.
Flame detection via either UV cell or ionization rod, even shared with ignition.
Possibility to use either electronic or winding transformers.
Burner status is visualized via a 7-segment display and led-bar.
Parameter setting via PC and USB device.
Provided with advanced self-diagnostic to assure a safe operation.
Voltage supplied to loads equal to voltage supplied to the device.
Housing available in polymeric material or die-casted aluminium.
Supervision of the burner can be implemented by traditional electrical wiring, or through built-in
communication line.
Designed and manufactured according to EN 298.
