Flame control with ionisation sensor
or UV sensor
Ignition and monitoring with a single
electrode
The automatic burner control units ignite and monitor gas burners in intermittent operation, i.e. the burners must be shut down once in every 24 hours. They are used in directly ignited gas burners of any capacity (ignition power ≤ 350 kW) in which, for technical reasons, pre-purging is omitted or controlled by a separate control system. Typical areas of application are industrial thermal process systems to EN 746 in the iron, steel, glass, ceramics, plastics processing and chemical industries. In addition, the IFS 258 are also suitable for use with atmospheric burners in other heatgenerating systems. The units are type-tested and certified in accordance with EC Directive 90/396/EEC for gas appliances in conjunction with EN 298.
