The OFID/ methanator control box is designed to shut off the heater of the OFID cracker while the gas loss is pursed. When the purge pressure is lost, the power to the OFID heater will turn off and the LED will light up to indicate that the purge is lost. When the purge pressure is re-established, the LED will turn off and the timer LED will light up. once the reactor is properly purged, power is restored to the OFID heater circuit. The system includes a timer bypass button that allows the user to bypass the cleaning timer.
