ESTRO Flame Control Device

The ESA ESTRO is a microprocessor operated flame 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 ionization sensors (electrodes) or UV radiation (UV-scan), continuously performing a periodic check of the flame sensor. The flame control device features a serial communication which allows remote burner control.

ESTRO units have inputs and outputs for controlling and supervising burners with permanent functioning, fit for applications in which the burners remain running longer than 24 hours.

The case is made of a durable glass fiber, allowing the application of the control device near the burner.
