Kromschröder BCU 4 Series burner control system's space-efficient design allows mounting the control unit close to burners, enabling better system integration. BCU 4 Series 460, 465 and 480 models offer options to increase utility and effectiveness of the control solution: 460 controls, ignites and monitors modulating or stage-controlled gas burners for intermittent or continuous operation; 465 incorporates airflow monitoring and pre-and post-ventilation for use with recuperative burners; and 480 can monitor pilot and main burners independently.
