240v
LAL1:Yellow and Blue Flame Burners without air pressure supervision
For oil atomizing burners of medium to large capacity
• For multistage or modulating burners in intermittent operation
• With or without air pressure supervision for checked air damper control
• Flame supervision
– with photoresistive detector QRB
– or blue-flame detector QRC1
– or silicon photocell detector RAR9
• Suitable for use with air heaters (WLE)
Use
• For the control and supervision of oil atomization burners
• For burners of medium to high capacity
• For intermittent operation (at least one controlled shutdown every 24 hours)
• Can be universally used with multistage or modulating burners
• Suited for use with stationary air heaters (WLE)
The flame supervision is ensured via a Photoresistive detectors QRB,blue-flame detectors QRC1 or Silicon photocell detectors RAR9.
