The induction heating systems are designed for manufacturing processes involving electrically generated heat. This includes applications in the plastic processing industry and the textile industry as well as drying processes in the paper industry. Induction heaters are increasingly being used to heat the tools such as rollers, rolls or cylinders. Not only are they emission-free, they can also provide the heat quickly and switch it off again just as quickly. The inductive heat (up to 250°C) can be evenly distributed and allows dynamic control exactly as required. Heating according to the eddy current principle The technology is based on the eddy current principle, in which a magnetic alternating field is generated with the help of high-frequency alternating current, which is introduced into the metal in a defined manner. The resulting eddy current losses generate a thermal power that can be precisely dosed by changing the current flow. Due to the exact controllability of the temperature, the heating process can be reproduced exactly, which ensures a high quality of the process. The temperature is measured directly in the jacket with up to four measuring points. In addition, uniform heating is achieved by a multi-zone design of the surface and roller inductor.
