Honeywell Kromschröder® Flame Detector Unit

Honeywell’s all-new Kromschröder Flame Detector Unit (FDU) series provides OEMs, burner manufacturers and end users with a state-of-the-art flame monitoring capability for gas burners across a wide range of applications – from hot-air furnaces and gas-fired boilers to industrial furnaces and excess-gas flaring installations.

Replacing Kromschröder’s IFW 15/50, R4343 and BC1000 flame relay models, the new FDUs enable multi-flame control or multi-point monitoring in conjunction with burner control units (BCUs) such as the Kromschröder BCU 560 or a failsafe PLC with a standard-compliant flame monitoring device.

There are two FDU models to choose from: the FDU 510 monitors gas burners in intermittent operation (applications of less than 24 hours) while the FDU 520 monitors gas burners in continuous operation (applications of more than 24 hours). The compact footprint of these units means that they can be easily integrated and mounted with other equipment in a cabinet, providing convenient access for maintenance and repair.
