Abstract

A method for producing a delivery module having an electric PTC heater, for installation into a tank for storing a liquid additive, includes: a) fixing a maximum electrical power that is made available to the delivery module; b) determining a thermal conductivity of the delivery module from a location of the electric PTC heater into the tank; c) calculating a switching temperature of the PTC heater based on the maximum electrical power and the thermal conductivity; and d) mounting a PTC material with a corresponding switching temperature for the PTC heater at the location.
