Unité de commande de brûleur Kromschroeder BCU460-5/1LW3GB (88610019)

Kromschroder 88610019 BCU460-5/1LW3GB is an automatic gas firing device control for industrial burners. Its electronic design ensures quick response to process demands, suitable for frequent cycling. It handles burners of any capacity, reduces central furnace control workload, and guarantees safe ignition after restarts. The user-friendly visualization system aids maintenance, while a new power management scheme cuts installation costs. Power for valves and the ignition transformer is supplied through the control box's power supply, protected by a replaceable fine-wire fuse, simplifying signal processing compared to conventional systems.
