The original resistance wire heating plate has relatively outdated working principles and heating efficiency. Our newly developed diffusion pump electromagnetic heater is a energy-saving heating device for the bottom of vacuum coating diffusion pumps. Its heating principle involves directly generating a magnetic field at the bottom of the diffusion pump, which then produces heat. This heat causes the bottom to heat up internally without heat conduction. The output power of the electromagnetic heater controller is controlled through PID analog signals. The heating coil, due to its own losses, becomes slightly warm but does not transfer heat to the iron. High-frequency alternating current passes through the heating coil, generating strong eddy currents within the iron, causing the iron to heat up. Choosing an electromagnetic heater for the diffusion pump to heat is an energy-saving method; modifying a 800MM diffusion pump for one hour can save 3-5 degrees of electricity. The electromagnetic heater for the diffusion pump replaces the original resistance wire heater, providing a more efficient and energy-saving heating solution. It brings a blessing to the vacuum coating industry, addressing the drawbacks of traditional resistance wire heating, such as slow heating speed, frequent breakage, low heating efficiency, high energy consumption, and frequent maintenance.

The advantages of the diffusion pump electromagnetic heater over resistance wire heating:

Energy-saving: Electromagnetic heating saves 40% more energy than resistance wire heating.

Environmental Protection: Reduced workshop temperature, saving cooling costs, heating plates requiring less frequent replacement, improved efficiency, good working conditions, and stable work efficiency.

Fast heating, stable operation, precise temperature control, quick installation, easy to operate.
Service Life: Over 5 years of normal usage.

Industrial electromagnetic heaters' application on diffusion pumps has brought a blessing to the diffusion pump industry. The electromagnetic heating principle of diffusion pumps converts electrical energy into magnetic energy, achieving high thermal conversion efficiency. It is used in plastic spinning machines, granulators, coating machines, cables, profiles, pipes, chemical fibers, diffusion pump electromagnetic heating, thermal oil, pipe heating, and more.
