Kromschroeder BCU460-3/1W3GBS3 (88610022) burner control unit

Kromschroder BCU460-3/1W3GBS3 88610022 is an automatic gas firing device control, managing, igniting, and monitoring gas burners for both intermittent and continuous operation. With a fully electronic design, it swiftly responds to diverse process requirements, making it suitable for frequent cycling.

Krom schroder BCU460-3/1W3GBS3 88610022 gas burner safety control box accommodates directly ignited industrial burners of any capacity, whether modulating or stage-controlled, and is installed near the burner for monitoring purposes. On industrial furnaces, it reduces the central furnace control workload by handling burner-specific tasks, ensuring safe ignition after restarts.

Service personnel benefit from a user-friendly visualization system for input/output signals and error history. A new power management scheme lowers installation and wiring costs, with power for valves and the ignition transformer supplied via the control box’s power supply, safeguarded by a replaceable fine-wire fuse. This setup contrasts with conventional systems used in industrial furnace and kiln construction, which require extensive signal processing over large distances.
