Abstract: Disclosed is a heater of a ureaaqueous solution supplying system for a selective catalyst reductor. The disclosed heater of the ureaaqueous solution supplying system for a selective catalyst reductor is mounted on a ureasolution tank which stores a ureaaqueous solution in order to defrost the ureaaqueous solution frozen under a low temperature condition. The heater of the ureaaqueous solution supplying system for a selective catalyst redactor comprises i) a PTC heater mounted inside the ureasolution tank to generate thermal energy by receiving electric power from a battery; ii) a piezoelectric sensor which is electrically connected with the battery and the PTC sensor, senses expansion pressure due to freezing of the ureaaqueous solution, generates electric energy according to the expansion pressure and applies a switching signal between the battery and the PTC heater; and iii) a cut-off sensor which is electrically connected with the PTC heater to cut off electric power applied from the PTC heater by increasing resistance when the temperature of the PTC heater is over the Curie temperature.
