Three coil challenges The induction coil, also known as an ‘inductor’, is essential to induction heating. Many factors contribute to a coil’s effectiveness: the care taken to make it, the quality of the materials used, its shape, its maintenance, its correct matching with the power source, etc. That’s why it’s so important to insist on professionally made and maintained coils. Here are just three of the many hurdles to be overcome in order to make safe and efficient coils: Challenge one: water flow and speed It is generally important to achieve an adequate flow of cooling water through the...

Designing and making induction coils is technically challenging. The details of every single EFD Induction coil are entered into a constantly updated database. As a result we can quickly and smoothly replace or repair any coil, anywhere—without compromising quality or productivity. Challenge three: magnetic flux concentrators Concentrators focus the current in the coil area facing the workpiece. Without concentrators much of the magnetic flux may propagate around the coil. This flux could engulf adjacent conductive components. But when concentrated, the flux is restricted to precise areas...

You’re never far from EFD Induction coil expertise and support services. From coils to complete solutions We’ve been developing induction-heating solutions for more than 65 years. Today, we’re one of the world’s largest industrial induction equipment makers, with sales and service companies, manufacturing plants and R&D centers around the world.
