Siemens LAL1.25 110V Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Siemens LAL1.25 110V is an automatic burner control unit optimized for atomizing oil burners of medium to high capacity. It orchestrates the entire burner operating cycle, including oil preheating, pre-purging, ignition, and continuous flame supervision via specialized photoresistive detectors. Essential for industrial oil-fired boilers, thermal fluid heaters, and heavy-duty furnaces, the LAL1.25 110V provides fail-safe monitoring and rapid shutdown in the event of fuel atomization or ignition failure. The LAL series stands out for its rugged construction, precise timing mechanisms, and extensive integration capabilities within complex industrial combustion safety chains.
