Industrial Burners for Energy Efficiency & Low NOx Emissions | Stiefel

Stiefel’s LED models visually confirm flames using low power (≤5W) white light in commercial boilers, while UV pilot lights verify ignition in harsh industrial furnaces with 254nm radiation. Both types integrate with flame sensors for a fail-safe ignition sequence: the pilot light first initiates, and main burner ignition occurs only after confirmation through UV/IR sensor. In a hotel’s boiler room, our LED pilot lights increased visible confirmation of attempted ignitions by 90%. The robust aluminum housing along with anti-vibration mounts endured over 5 years of uninterrupted operation.
