MICROPROCESSOR OPERATED BURNER CONTROL DEVICE
ESA ESTRO SERIE
INTRODUCTION
ESA ESTRO is a microprocessor operated device, designed to
control gas and oil fired burners, discontinuously operated.
This device warrants the safe operation of combustion unit at
one or two stages (pilot and 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 the environment temperature will remain below 60°C.
APPLICATIONS
- One or two stages (pilot and main) discontinuous burners;
- Flame detection by means of rod, unirod and UV scan (also
combined);
- Packaged burners managing a complete ignition cycle
(blower, air damper, air pressure switch);
- Burners with air valve control for furnace purging, burner
ignition and thermoregulation (heating/cooling) via external
regulation device;
- Combustion plant with burners controller via digital signal or
ECS serial communication;
- Customized burners operation through programmable
expansion cards.
