Dingli New Energy Equipment Co., Ltd. specializes in the research and application of electromagnetic induction heating technology. Its rotary electromagnetic heating equipment features innovative design and superior performance, delivering efficient, energy-saving, and environmentally friendly solutions for industrial heating, drying, pyrolysis, and calcination. This enables enterprises to achieve green production while significantly reducing costs.
In the fields of industrial heating, drying, pyrolysis, and calcination, electromagnetic induction heating technology is rapidly replacing conventional methods thanks to its superior efficiency, energy savings, and precise temperature control. As a leading Chinese enterprise in electromagnetic heating technology and equipment, Dingli New Energy’s independently developed rotary electromagnetic systems offer substantial technological advantages and strong market value across these applications.
Conventional heating, drying, pyrolysis, and calcination processes typically rely on coal, gas, oil, or resistance heating, which suffer from high energy consumption, poor temperature control accuracy, and significant environmental pollution. In contrast, Dingli’s electromagnetic heating equipment utilizes high-frequency electromagnetic induction to directly heat materials internally, achieving rapid and uniform heating with thermal efficiency exceeding 90%. This substantially reduces energy use and production costs while eliminating open flames and exhaust emissions, enabling truly clean production.


Utilizing the principle of high-frequency electromagnetic induction, electromagnetic heating equipment acts directly upon the interior of metallic or non-metallic materials to achieve rapid and uniform heating; with a thermal efficiency exceeding 90%, it significantly reduces both energy consumption and production costs.
