A renowned automotive supplier from Germany has recently started using the AQON Hi' Tension System and the Hi' Pure Filter to improve the cleanliness of the coolant circulation during grinding of carbide materials. Previously, there were recurring quality issues caused by grinding comma, sediment formation, and frequent coolant changes. The Hi' Tension System now effectively filters out particles in the range of 5 µm - 15 µm. The Hi' Pure Filter even removes particles down to a fineness of 1 µm.

Hi' Tension: The difference is noticeable after just 1 hour

Comparison of the filter results without (left) and with (right) integrated Hi' Tension System in the feed of the vacuum belt filter (see Fig. 1 and Fig. 2).

Without Hi' Tension

The particles from the grinding process are finely distributed in the coolant. Due to the fineness of the particles, they can only be inadequately separated by the separation boundary of the vacuum belt filter (Fig. 1).

With Hi' Tension

The particles agglomerate, forming a cohesive structure. As a result, the existing filter (here: vacuum belt filter) can remove significantly more and finer dirt particles (Fig. 2).

Hi' Pure: 6.5 kg of fine dirt filtered out in just 2 hours

The existing filtration system, consisting of a magnetic separator and hydrocyclones, was integrated with the Hi' Pure Filter in the bypass (see Fig. 3 and Fig. 4).

Coolant purity increased

After filtration through the Hi' Pure Filter, particle contamination is no longer visually perceptible. The coolant purity has been effectively increased (Fig. 3).

Effective filtration

The filter element of the Hi' Pure Filter effectively separates particles down to 1 µm due to its design and the agglomeration effect of Hi' Tension (Fig. 4).

Advantages of Hi' Tension and Hi' Pure

- Performance enhancement of existing filter technology
- Reduction of grinding comma formation
- Higher coolant purity
- Increased cleanliness of machines and pipelines
- Separation of fine debris that cannot be separated by magnetic separators or hydrocyclones due to their design
