TDM demagnetizer for demagnetizing large and complex components

Tunnel demagnetizer TDM

When to choose a tunnel demagnetizer:

Tunnel demagnetizers are designed for demagnetization of large components with a cylindrical or square shape or for bulk demagnetization of thin-walled components. The dimensions of the component should be similar to those of the tunnel opening. They are designed for continuous operation, so they can be used in industrial production in connection with belt-type or roller-type conveyors in automated production plants.


  • Solid aluminium structure
  • High power with the possibility of continuous operation
  • Overheating protection
  • Demagnetizing core firmly fixed by high-strength resin
  • 3 m power supply cable

Detailed description:

The TDM tunnel demagnetizer is designed for continuous operation. It is used for the elimination of residual magnetism in series produced workpieces and/or components such as moulds, bearings, and component parts in automated production plants. The tunnel demagnetizer operates on the principle of a gradually weakening alternating current, which eliminates the magnetism to a certain depth. For optimum performance, it is necessary to select a suitable dimension so that the workpieces are in as close as possible contact with the aperture of the device.

Important parameters:

  • Application: Electro
