The original resistance wire heating disk is relatively outdated in terms of working principle and heating efficiency. Our newly developed diffuser pump electromagnetic heater is a power-saving heating device specifically designed for the bottom of a vacuum deposition diffuser pump. Its heating principle involves directly generating a magnetic field at the bottom of the diffuser pump, which then generates heat. This causes the bottom to heat up on its own, without any heat conduction. The output power of the electromagnetic heater controller 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 on its own. Choosing an electromagnetic heater for the diffuser pump is a power-saving method; modifying a 800MM diffuser pump for one hour can save 3-5 degrees of electricity. The electromagnetic heater replaces the original resistance wire heater, offering a more efficient and power-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.

The advantages of an electromagnetic heater for diffusion pumps over resistance wire heating:

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

Environmental Protection: Reduces workshop temperature, saves cooling costs, heating disks do not need frequent replacement, improves efficiency, good working condition, stable work efficiency.

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

Industrial electromagnetic heating transformers for diffusion pumps have 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. They are applied in plastic filament extruders, granulators, coating machines, cables, profiles, pipes, chemical fibers, electromagnetic heating for diffusion pumps, thermal oil, pipe heating, and more.
