Emission-free into the production of the future: Heat inductively!

In many industrial processes it is important to generate heat. Often, this heat must be available quickly and it must be possible to turn it off just as quickly. In addition, this heat must be distributed evenly and must be able to be controlled dynamically and according to demand. The heating should also require as little energy as possible.

With inductive heating systems from Kendrion you can expect efficient, precise and clean solutions for your heated tools. Find out more now!

    Induction heating - The superior heating strategy in industrial processes

    Connectable to PROFINET ETHERCAT CANopen or another fieldbus system.
    The modular heating system (MHS) consists of a controller and up to seven generator modules that supply inductors with optimally adapted power.

    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°) 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.

    Kendrion offers energy-optimised induction heating systems whose components are precisely matched to each other.

    The Kendrion induction generators are designed as a modular system. They consist of a controller and up to 7 stackable induction generators. The controller can be integrated into the control of a machine via a fieldbus interface (e.g. Profinet®). The control of the individual induction generators and the retrieval of status messages is carried out for all connected generators via the central controller. Depending on the configuration, the controller can also control the heating channels with integrated PID controllers. The units are designed for installation in control cabinets.

              FAQs: Inductive Heating

              What is induction heated in industrial processes?

              Induction heating is a fast and non-contact method of heating metals, preferably ferrous metals.

              What is inductive heating used for?

              Inductive heating systems from Kendrion are used in machines where process heat is required, such as heating rolls or tools. They are used in food processing, the textile industry or the printing and paper industry.

              How does induction heating work?

              A high-frequency alternating current is applied to an induction coil, which generates an electric field. The workpiece to be heated is placed in this field. The resulting eddy currents generate heat directly in the workpiece.

              What does an induction heating system consist of?

              An industrial induction heating system usually consists of an induction generator and an inductor. With Kendrion's Modular Heating System, systems with up to seven generators and 42 inductors can be built.

              What are the advantages of induction heating?

              Temperature, heating time and heat pattern are reproducible. With inductive heating systems, you can convert 90% of the expended energy into usable heat without burning fossil fuels. Process temperatures are reached in a very short time for typical workpieces thanks to high surface power and low masses. By designing the inductors and using multiple heating zones, a very precise surface temperature can be achieved, while the entire heating process can be controlled by induction generators and process control software.
