The original resistance wire heating plate is relatively outdated in terms of working principle and heating efficiency. Our newly developed diffuser pump electromagnetic heater is a energy-saving heating device specifically designed for the bottom of vacuum coating diffuser pumps. Its heating principle involves directly generating a magnetic field at the bottom of the diffuser pump, which then produces heat. The heat causes the bottom of the diffuser pump to heat up on its own without any heat conduction. The output power of the electromagnetic heater is controlled through PID analog signals. 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 the iron to heat up and spread the heat. Choosing an electromagnetic heater for the diffuser pump is a way to save energy. Refurbishing a 800MM diffuser pump for one hour can save 3-5 degrees of electricity. The diffuser pump electromagnetic heater replaces the original resistance wire heater, providing an energy-saving heating device with better heating performance. 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.

Advantages of the diffusion pump electromagnetic heater over resistance wire heating:

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

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

Quick heating, stable operation, precise temperature control, easy installation, and user-friendly operation.
Life span: Over 5 years of normal usage.

Industrial electromagnetic heaters' application on diffusion pumps brings 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.
