Beschreibung
Zusammenfassung:	The heating device has heating elements (210,220) that are arranged in parallel and switched to provide a predetermined heating power over a predetermined voltage range of supply voltage to maintain a specific temperature range of aqueous urea solution. The heating element is formed meander-like or in grid shape. The temperature range of the aqueous urea solution is -40-+20[deg] C. The heating elements provide a maximum temperature of 120[deg] C. Eine Heizeinrichtung für ein Dosiersystem für ein flüssiges Medium, insbesondere eine Harnstoff-Wasserlösung ist dadurch gekennzeichnet, dass sie wenigstens ein Heizelement (210, 220) umfasst, das über einen vorgebbaren Spannungsbereich der Versorgungsspannung und einen vorgebbaren Temperaturbereich des flüssigen Mediums eine vorgebbare Heizleistung zur Verfügung stellt.
