REDUCTANT SUPPLY LINE HEATING SYSTEM

A system including a reductant tank, a receiver, a first valve, a reductant supply line, a plurality of sensors, and a controller is provided. The reductant tank is configured to store a reductant. The receiver is configured to receive a supply of the reductant from an off-board reservoir. The first valve is in communication with the reductant tank and is configured to control a reductant flow into the reductant tank. The reductant supply line is in fluid communication with the receiver and is configured to provide the reductant flow to the first valve. The plurality of sensors is configured to generate a signal. The controller is in communication with the plurality of sensors. The controller is configured to issue a command to a heating element to modulate a temperature of the reductant supply line based, at least in part, on the signal generated by the plurality of sensors.
