Product Profile of Burner Control Devices
ESA-Pyronics offers ESA ESTRO a microprocessor operated flame-controlling device equipped with inputs and outputs for the ignition and control of industrial burners. There exist 3 different versions of the same device. ESTRO B 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. ESTRO C is for one-stage burners [only one gas valve]. Remote control via electric and serial signals with normally open output when the burner is on. ESTRO Q is for one-stage burner [only one gas valve], remote control via serial signals. On the front panel there is a lock/reset button, a cycle display, a flame-signal indicator and two LEDs to send and receive the infrared signal. A fixed luminous code corresponds to normal operating conditions whereas a blinking code means there is some lockout conditions or flame failure, requiring the intervention of an operator.
