Z 726 K
Burner control
Self-monitoring and fail-safe burner controls for the integration into the Hegwein burners and igniters.
Overview
- Controlling and monitoring of gas and oil burners/gas and oil fired igniters of any capacity
- Suitable for intermittent operation (Z 726 K2...) and continuous operation (Z 726 K3..., Z 726 KH..., Z 726 KE...)
- Optional pre-purge of the combustion chamber with changeable pre-purge time and air pressure check
- Optional changeable safety times
- Optional input for external flame monitor
- Optional re-cycling after flame loss in operating position
- For Z 726 KH... und Z 726 KE...: Bargraph display and config-switch
- For Z 726 KE...: Complete function range with 16-pin plug connector for not safety-related 4 - 20 mA output signal
Applications
- Chemical industry
- Refineries
- Cement plants
- Waste incinerators
- Steam generators
- Heating plants
- Industrial furnaces
