LFL1.322 gas burner for fixed air heater, t1=36s, TSA=2s, t9=2s, AC230V minimum order quantity 10 pieces
LFL1... burner control device is specially designed for forced air burner control and monitoring. It can be used for direct ignition or medium and high power burners with ignition burners. Fuel gas is universal and can be used for fixed preheated air burners WLE according to DIN 4794 standard
The difference between 01 series and 02 series is: ① the safety time of ignition burner with ignition gas valve is different; ② the controller of high-power atmospheric combustion is LFL1.638; if the burner needs continuous operation control, ③ the safety time of burner with ignition gas valve is different.
After the allowed afterburning time of LFL1, the detection electrode and flame simulation test are immediately restored. The fuel valve that is not closed or not completely closed will lock the controller unit of the burner immediately after the allowed afterburning time. The detection electrode and flame simulation inspection only ends when the pre-purge time at the next burner start is completed- During each start-up of the burner, the correct action of the flame monitoring circuit is automatically checked- The controller contact used to release fuel shall be inspected within each post-purge time to ensure that the contact is not closed- A built-in fuse unit protects the contact of the controller from overload.

Combustion controller • Medium and large capacity burners for forced ventilation of fuel oil, gas or dual fuel • Intermittent operation burners for multi-section or continuous proportion • With damper detection • Flame monitoring – UV flame detector QRA... – The ion probe LFL1... series controller is particularly suitable for OEMs integrating combustion control into their products Purpose - monitor the forced draft burner with expansion flame or pilot fire (ignition) interruptible structure - medium to large capacity - intermittent operation (at least one controlled shutdown every 24 hours) - multi-section or continuous proportional burner - dual fuel burner - fixed air preheater 01 and 02 series. For pilot fire (ignition) burner with pilot fire gas valve, the main reason is the length of safety time. LFL1.638 is suitable for large-capacity atmospheric burner |
