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.
