Controlled demagnetizer

These industrial demagnetizers consist of demagnetizing tunnel coils and power modules. The digitally controlled power module guides precisely the demagnetization process. This approach enables efficient solutions for different applications. The controlled demagnetizer machines are most often set for the pulse method. In the case of continuous or endless material flow, they can also be configured for a continuous demagnetization process. In some special cases best results are obtained by using both methods in combination (pulse demagnetization with continuous passage of the parts -> continuous pulse method).

The power modules and the demagnetizing coils are available in various sizes (see tables below). In cases where standard sizes can’t be used, customer specific variants may be designed.

Some typical fields of application of these industrial demagnetization machines: removing magnetism of:

  • parts in transport or washing baskets prior to cleaning machines
  • parts before eddy current testing
  • produced parts to meet residual magnetism limits
  • tools, clamping or gripping elements
  • semi finished steel products

The controlled demagnetizers are not only suitable for specific applications. They are also interesting in cases where an economical and universally applicable solution is required for shop floor and industrial production.

Demagnetizing coils:

The copper windings of the demagnetizing coils are calculated and designed for maximum field strength and lifetime. The coils are completely encapsulated, electrically insulated and protected against overheating with temperature monitoring. Connection to the power module is done by cables of customer specific length.

(1) The active area defines the volume of the coil enveloped by the copper winding.

(2) The performance data (field strength, frequency, demagnetization method etc.) is determined optimally in a project specific manner.

(3) Standard power modules for a coil. Other combinations on request.

Power modules:

The power module contains the power electronics for generating the controlled alternating current required in the demagnetizing coil. We trust for a long term worldwide availability of spare parts exclusively on hardware from leading electronics companies. Cestriom GmbH holds the core know-how in its own hands by designing the power modules, programming the PLC’s and setting the power electronics on its own.

Further development goals of our power modules are simple maintenance and high availability. All relevant settings and parameters are stored completely digitally. This concept not only allows know-how protection, but also permits easy restoring of the specific machine settings only by downloading software and parameters. The digital design with most recent electronics furthermore enables modern remote maintenance concepts by internet.

The power modules are designed by standard for manual and remote operation. Communication is done via 24V isolated signals in automated (remote) operation mode (further communication variants on request). The demagnetization process parameters are controlled by a PLC. If needed the parameters can easily be changed on a display (optional) within a wide range.
