The basis for reliable induction heating
Sophisticated rectifiers, robust IGBT inverter modules, highly efficient resonant circuit components combined with the microprocessor-based highspeed eldec control architecture provide a product that is unrivalled on the market in terms of matching range, efficiency, energy metering as well as reliability. Built many thousands of times. Continuously developed.
The PICO, ECO-LINE EEI², SYSTEM-LINE, RACK-LINE and CUSTOM-LINE product lines include medium-frequency and high-frequency generators from 5 to 1,500 kW as well as DF and SDF® generators from 50 to 3,000 kW.
How induction generators work
Induction generators produce an alternating magnetic field which induces eddy currents in electrically conductive materials. Heat is generated as a result of the material’s electrical resistance and demagnetisation losses – and this occurs without contact, directly within the component.
This contactless energy transfer enables efficient, precise and technically sophisticated applications whilst maintaining high levels of efficiency.
The penetration depth, heating rate and temperature profile can be precisely controlled via the frequency and power of the input current.
Depending on the frequency range, a distinction is made between:
- Low-frequency generators (LF)
- Medium-frequency generators (MF)
- High-frequency generators (HF)
At eldec, the product range is further expanded to include DF generators and SDF® generators:
Dual-frequency generators:
Switchable dual-frequency generators
Simultaneous dual-frequency generators:
Patented dual-frequency generators that can be operated simultaneously. During the SDF® process, the medium-frequency fundamental oscillation is superimposed by a high-frequency oscillation.
Our induction generators are used in a wide range of applications and processes, such as heating, brazing, annealing, deburring, etc., across a variety of industries.
