SE + DN Demagnetization plant. Optimized for common washing basket sizes. Demagnetization in pulsed or continuous operation.
  • Reliably reduces residual magnetism of bulk, layer material and settled material, preventing ferromagnetic particles from adhering to surfaces, which otherwise are not washed off during parts cleaning
  • Especially designed for the high residual magnetism requirements relating to safe washing processes
  • As compared to continuous flow systems, the SE coil reaches a field strength that is multiple times higher thanks to pulse demagnetization
  • The coil openings are optimized for common laundry basket sizes and a productive and efficient demagnetizing
  • Two demagnetizing coils (Helmholtz coil) are combined in order to efficiently and reliably demagnetize even long baskets with only one demagnetizing pulse
  • Space-saving integration, because no discharge run is needed

Maurer Magnetic

Magnetically pure

Today, cleaning system manufacturers only guarantee residual soiling targets up to a specific residual magnetism limit for ferromagnetic components, making it necessary to integrate powerful demagnetizing processes into the technical process. Maurer Magnetic is positioned for this sector with its SE + DN series. The performance capability depends on the current requirements of the cleaning system manufacturers.
The SE series is designed for general demagnetization. The requirements of the demagnetizing performance are higher in cases where the demands are increased because limit values need to be observed. For fine and ultra-fine cleaning, residual magnetism values of < 2 A/cm are critical. Here, we recommend the high-performance VE or HLE series.

In 2001, Maurer Magnetic developed the Maurer Degaussing® demagnetizing process, for which a patent was applied for. With our many years of experience and the expertise we have acquired over time, our technology has been continuously enhanced, while our new relevant patents supplement it. Our in-house production also allows us to implement customer demands quickly and unimpeded, while ensuring our quality standards at the same time.

Applications

Cleanliness under control

Demagnetizing as process preparation prior to industrial cleaning processes

The effect of residual magnetism that is too high is that an attraction force acts upon ferromagnetic dirt particles. The magnetic attraction forces increase disproportionately closer to the component surface, which makes cleaning even more difficult despite modern and efficient washing processes. The cleaning methods are not able to effectively remove these particles. So, process reliability can only be achieved by demagnetizing the parts before they are cleaned.
