National standard urea freezes below -11℃, so in cold regions, urea often needs to be thawed before it can be used normally. This necessitates the use of urea tubes with heating functions. The main heating methods are resistance wire heating and PTC resistance element heating. Each method has its advantages and disadvantages: resistance wire heating offers stable and uniform heating but has a short lifespan and is prone to breakage; PTC resistance element heating is safe, energy-efficient, and has automatic temperature control, but is prone to uneven heating. Zhengyang Electronics can provide solutions for different heating functions of urea tubes.
