Delta-Elektrogas CFK Burner Control System

Delta-Elektrogas CFK Burner Control System is an advanced, microprocessor-based management unit designed to automate and monitor the ignition and flame supervision of atmospheric or fan-assisted gas burners. Engineered to comply with the rigorous safety standards of EN 298, the CFK series provides a comprehensive “all-in-one” solution for sequence control, managing critical phases from pre-purge and spark ignition to continuous flame monitoring via ionization or UV sensors. By integrating failsafe logic and diagnostic status indicators into a compact, plug-in design, the CFK system ensures maximum operational safety and minimized downtime for industrial thermal processing equipment, including boilers, ovens, and space heaters.

Features Of Delta-Elektrogas CFK Burner Control System

Automated Sequence Control: Manages the entire burner lifecycle, including pre-purge (cleaning the combustion chamber), ignition timing, and safety intervals to prevent gas buildup.
Dual Flame Supervision: Offers flexible monitoring using either an Ionization Probe (flame rectification) or a UV Sensor, providing a failsafe lockout if the flame is not detected or is lost during operation.
Integrated Ignition Transformer: Certain models feature a built-in high-voltage ignition system, which simplifies installation by reducing external wiring and the number of components in the gas train.
Airflow Verification: Includes a dedicated input for an Air Pressure Switch, ensuring the combustion fan is functional and providing sufficient oxygen before the gas valves are permitted to open.
Visual Diagnostics & Reset: Equipped with a multi-color LED button that communicates the system status (Operation, Standby, or Lockout) and allows for both local and remote resetting of the controller.

Application Of Delta-Elektrogas CFK Burner Control System

Forced-Draft Gas Burners: Managing the complex startup sequence of fan-assisted burners, where the system must verify airflow via a pressure switch before initiating the ignition spark.
Industrial Steam Boilers: Serving as the central safety controller for boilers in food processing or textile plants, ensuring immediate gas shut-off if the flame is extinguished during high-demand steam production.
Commercial Cooking Equipment: Providing reliable flame supervision for high-capacity industrial ovens, rotisseries, and large-scale catering grills where safe, automated ignition is required for non-technical staff.
Atmospheric Heating Systems: Controlling the ignition cycle of natural-draft furnaces and space heaters, using ionization probes to monitor flame stability in warehouse or workshop environments.
Process Drying & Curing: Automating the burner cycles in paint booths, ceramic kilns, and grain dryers where precise timing of the pre-purge and ignition phases is critical to prevent the accumulation of volatile vapors.
