The original resistance wire heating plate has relatively outdated working principles and heating efficiency.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 specifically designed for the bottom of vacuum deposition 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 of the diffusion pump to heat up naturally without heat conduction. The output power of the electromagnetic heater controller is controlled by a PID analog signal. The heating coil slightly heats up due to its own losses 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 it to heat up. Choosing an electromagnetic heater for the diffusion pump is an energy-saving method; modifying a 800MM diffusion pump for one hour can save 3-5 degrees of electricity. The electromagnetic heater replaces the original resistance wire heater, providing a more efficient and energy-saving heating solution. It brings a blessing to the vacuum deposition 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.

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: Reduces workshop temperature, saving cooling costs, heating disks require less frequent replacement, efficiency improved, good working conditions, stable work efficiency.

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

Industrial electromagnetic heating units' application in diffusion pumps has brought a blessing to the diffusion pump industry. The electromagnetic heating principle of diffusion pumps involves converting electrical energy into magnetic energy, offering a high thermal conversion efficiency. It is used in plastic spinning machines, granulators, coating machines, cables, profiles, pipes, chemical fibers, diffusion pump electromagnetic heating, heat transfer oil, pipeline heating, and more.
