Estro B2 – Burner Management Box
ESA Estro is a device for two-stage burners (pilot and main gas valves). Remote control via electric and serial signals with powered output when the burner is on.
The 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. Additionally, the thermal resistant case of ESA ESTRO allows its installation on burner proximity, provided that the environment temperature remains below 60°C.
