Overview
- Controlling and monitoring of gas and oil burners/igniters of any capacity.
- Suitable for intermittent operation (D-GF 75-10, ASD-75 POI) and continuous operation (D-GF 75-20, ASD-75 POD)
- Prepurge of the boiler with changeable prepurge time and optional air pressure check
- Changeable safety times
- Input for external flame monitor
- Optional re-cycling after flame loss in operating position
- (for D-GF 75): Integrated ionisation flame monitor
- (for ASD-75): Input for a 90-110 VDC flame signal
Applications
- Chemical industry
- Refineries
- Cement plants
- Waste incinerators
- Steam generators
- Heating plants
