The method used in the design process of electric heating tubes is fundamentally different from the design steps of ordinary mechanical or electrical components. It focuses on the practicality of closely matching the environment with the functions used, while the design work of electric heating tubes includes two parts: product technical design and product manufacturing process design. In these two major design contents, the technical design of the product mainly focuses on the work of all state-owned characteristic indicators of the product. As a designer, the thinking mode and actual work ability level can be fully utilized and demonstrated through specific product design. The main content of process design is to determine the process operation methods and process assurance measures to ensure that the end product meets the design indicators during the production process. In the process of process design, attention should be paid to the operation methods used to meet the technical performance of the product and the auxiliary design of process engineering to improve operation efficiency.

The electric heating tube auxiliary heater is equipped with a temperature controller from a well-known domestic brand, which can set high and low temperatures independently. It is also equipped with an overheat protection device to control the water temperature of the equipment and prevent damage to components due to water shortage and high temperature protection.
