Research Goal

Simplification of filtration (optimization of filter system performance), reduction of residual dirt load – higher purity – safe quality – lower fluid costs

Since early 2016, successful experiments at the Tool Laboratory (WZL) of RWTH Aachen have demonstrated the effect of pulsed high voltage* on particulate contaminants in water-based cutting fluid emulsions. Metallic particles reached sizes of up to 36 μm. The filter cake formation could be improved by a factor of three. The laboratory experiments were supplemented by an additional installation at a well-known automotive company on Lake Constance. Particulate-relevant contaminants could be reduced by up to 75%.

The advantages of pulsed high voltage: High Tension System (HTS)

- Achieving higher purity classes with simple filter technology and filter cloth structure
- High, consistent filter performance
- Optimal cleanliness, protection of tools, workshops, systems, and pipelines
