Control methods for high-power electric heaters~
Thread Content
The company is planning to add another 2100KW electric heater for use in a different position; it’s the type made up of multiple electric heating elements. What would be the best way to control it? Is it better to use AC contactors for group control, or a thyristor voltage regulation cabinet? What are their respective advantages and disadvantages?
I’m not sure what your specific process requirements are; I have previously built 2000KW thermal oil electric heaters that used thyristor-based voltage control.

High-power electric heaters are all controlled in groups, with one or two of these groups being controlled using thyristor power regulation, via PWM! When the adjustable power set exceeds its regulation capacity, one set of non-adjustable power sets is increased or decreased.
Hello, I am also facing the issue that high-power electric heaters require AC contactors of relatively large size. Could you advise whether alternative electronic components can be used instead? Thank you!
