The compatible flame detection photocell for biomass pellet burners is an extremely useful accessory that ensures the proper and safe operation of your burner. Using photoresistance technology, it monitors the combustion flame, providing immediate feedback on the status of the combustion process. If a flame is detected inside the boiler, the photocell interrupts the burner's operation before the activation of the electromagnet valve, thus offering additional protection to the system. Its autonomy and technology make it ideal for your burners.
