Honeywell introduced the next-generation Kromschröder BCU 4 Series, an all-in-one control solution for multi-burner applications. Replacing an earlier product line, the BCU 4 Series 460, 465, and 480 models incorporate a range of refinements and new features designed for simplified engineering, installation, and start-up. They are also designed to provide various options to increase utility and effectiveness of the control solution — including a space-efficient design that allows the unit to be mounted close to a burner versus in a separate cabinet, enabling better system integration.

The BCU 4 Series offers industrial designers, engineers, operators, and service technicians a multi-functional, modular control solution. It is designed for directly ignited or pilot/main burners of unlimited capacity in intermittent or continuous operation, and for modulated or step-controlled gas burners. The BCU 4 Series was developed for furnace builder OEMs, burner manufacturers, and end-users in sectors such as metals, ceramics, food, and automotive.

The three models in the series provide different functions:

  • The BCU 460 model controls, ignites, and monitors modulating or stage-controlled gas burners for intermittent or continuous operation, making it ideal for frequent cycling operations; 
  • The BCU 465 incorporates airflow monitoring and pre- and post-ventilation for use with recuperative burners; and
  • The BCU 480 can monitor pilot and main burners independently.

The BCU 4 Series comes equipped with an ignition transformer, burner control, and an embedded human machine interface (HMI) — all arranged within compact housing. The four-digit display shows vital information such as program status, unit parameters, and flame signals. All models possess a manual mode to adjust the burner and its diagnostics.
