Estro Q2 – Flame Controlling Device

Industrial Combustion

ESA ESTRO is a microprocessor operated device, designed to control gas and oil fired burners, which are discontinuously operated. This device warrants the safe operation of the combustion unit at one or two stages (pilot/main burners), it controls the air flow rate and allows the detection of flame presence through ionization (electrodes) or UV radiation (UV-scan). ESA ESTRO is equipped for serial communication, allowing a remote burner control and operation. The thermal resistant case of ESA ESTRO allows its installation on burner proximity, provided that the environment temperature remains below 60°C.
