Rising quality demands on surface quality and the increased use of multifunctional machine tools, e.g., with integrated grinding processes, lead to an ever-increasing load of fluid media with fine dirt or fine debris.

Conventional centrifuges or filter systems can only separate contaminants of 5 – 15 μm or, in the case of lightweight materials, only with enormous effort or, in extreme cases, not at all from fluid media.

The cause of this lies in physical laws or the critical limits of the possible filter fineness or centrifugal forces, where either the performance is too strongly limited or the medium's composition is altered.

With the High Tension System (HTS), AQON has developed an efficient and retrofittable solution for cost-effective and high-performance filtration of fine contaminants. (see Fig. 1)

The HTS alters the adhesion and binding behavior of particles through dipole induction. Particles agglomerate and form larger composite structures. The contaminants enlarged up to a factor of 30 can thus be safely and easily mechanically filtered with existing fleece or endless filter systems, even with nominal filter finenesses of 40 or 60 μm. (see Fig. 2)

The load caused by particles, especially those in the size range of 5 – 15 μm, can be improved by several ISO 4406 cleanliness classes or reduced by up to 70%. Using filter fleece with an average fineness of < 40 μm, the load can be reduced even by up to 90%. Simultaneous improvement of the filter cake structure significantly reduces the consumption of filter material. (see Fig. 3)

Practical significance: Besides a significant improvement in filtration quality, the use of HTS mainly leads to a reduction in ongoing filtration costs of up to 80% and a space saving of up to 55% when designing filter systems. (see Fig. 4)

Additional advantages of the High Tension System

- Universal: Integrable into all existing systems in full or partial flow, for individual machines, groups, or central systems
- Sustainable: Energy requirement for a filter capacity of 10 m³/h is only 50 watts
- Safe: Without mechanical or rotating parts
- Process optimization: No restrictions on the necessary filter performance
- Cost-saving: Enables the omission of expensive auxiliary equipment and the use of costly fleece or endless filters that restrict performance

The High Tension System is suitable for:

- Coolant lubricants (KSS), washing, degreasing, grinding, blasting, and electroplating media
- Contaminants from all metals and non-metals (e.g., aluminum, graphite, ceramics, glass, silicon, plastics, and more)
