The structure, function and welding process of electric heater

The duct type electric heater is different from ordinary electric heaters in terms of structure and function. Of course, its production will also have a series of strict requirements. In addition to understanding the basic composition of the duct type electric heater, we also To be familiar with its function and production process.

The air duct type electric heater is mainly composed of the main body and the control system. The heating element is made of stainless steel pipe as a protective sleeve, and a series of materials such as high temperature resistance alloy wire and crystalline magnesium oxide powder are placed inside, which are formed by a compression process. And its control part is composed of advanced digital circuits, integrated circuit triggers, high back pressure thyristors, etc., which realizes an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.
