Foreign metal particles are the cause of many problems in the non-food industry. Magnets remove these often tiny metal particles and ensure that the basic properties of the raw materials remain intact.

The consequences of metal contamination

Discolouration of detergents or coatings if rust is present. They can also cause major damage in the processing of gas and oil, during combustion in a turbine or motor.

Undesirable metal particles can also change the product properties. Like the conductivity of carbon black, for batteries.

When fabricating plastics, unwanted metal particles reduce the insulation value of cables.

These negative effects can be avoided by applying magnets.

Magnetic filters

Magnetic filters meticulously and efficiently remove rust and small weakly magnetic metal particles our of chemicals. They help to recover ferromagnetic catalysts.


This prevents damage and results in significant savings. The material choice of the magnet is particularly important. The product may be caustic and damage the seal or housing.


The system must also be completely self-cleaning and be able to be used in high-pressure processes. We have developed various magnetic separators to choose from.
