Industrial demagnetizer

Cestriom industrial demagnetizers are made of high power demagnetizing coils and optimally adapted power modules. The digitally controlled power modules guide precisely the demagnetization process. This approach enables efficient solutions for demanding applications. In high field applications, the demagnetizer machines are usually set for the pulse method. In continuous or endless material flow applications, the machines are configured for a continuous demagnetization process.

The product range includes many variants of power modules and demagnetizing coils (see tables below). When standard sizes do not fit, Cestriom Engineers can design specific systems.

Typical applications of these industrial demagnetization machines are:

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

Our industrial demagnetizers are not only suitable for very specific applications. They are also interesting where an economical and universal solution is required for industrial production.

Demagnetizing coils:

The windings of the demagnetizing coils are designed for maximum field strength and lifetime. The coils are completely encapsulated, electrically insulated and protected against overheating by temperature monitoring.

(1) The active area defines the volume of the coil enveloped by the winding. The dimension WxH corresponds to the passage of the coil.

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

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

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 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.

Our power modules are designed for 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 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. All relevant parameters can be easily changed on a digital display.
