Estro PO – Flame Controlling Device

Industrial Gas and Oil Burner Controller. Available in three types:
Estro B2

ESA ESTRO is a microprocessor operated industrial burner control device that controls gas and oil fired burners for continuous operation. This device safely controls one or two stage burners (pilot and main), combustion air, and is able to detect the flame signal via ionisation sensors (electrodes) or UV radiation (UV-scan), continuously performing a periodic check of the flame sensor. The flame control device is equipped with a serial communication which allows remote burner control. The case is robust allowing the application of the control device near the burner.
