LAVASONIC HI: NEW GENERATION OF BOTTLE WASHERS

As an exhibitor at the ALLFORPACK EMBALLAGE PARIS 2026 trade fair, Krones is highlighting a major innovation in the field of bottle washing with the introduction of the Lavasonic HI.

In bottle return lines, the washer is a key element in terms of both hygiene and resource management. The machines in operation today are based on proven technology, but their large size makes them difficult to integrate into installations optimised for compactness. At the same time, increasing variations in the level of soiling, the continuous rise in energy costs and high sustainability targets are redefining expectations for washing equipment. It is in this demanding environment that Krones is introducing the Lavasonic HI, designed to combine efficiency, flexibility and a measurable reduction in environmental footprint.

The pre-treatment zone incorporates ultrasonic technology using targeted cavitation. Tiny bubbles form in the wash bath before imploding in a controlled manner, effectively removing dirt and label residue. This dynamic promotes better diffusion of the cleaning product, accelerates the removal of residues and reduces the amount of particles transported to the soda. It also helps to reduce chemical consumption and extend the bath's usage cycles, thereby stabilising the entire process.

Beyond pre-washing, the Lavasonic HI incorporates a high-intensity module, which has become an integral part of the process. Its ability to finely adjust treatment parameters allows it to adapt to bottles with varying degrees of soiling depending on retrns. This flexibility plays an essential role when the origin of the bottles or the collection conditions differ from one batch to another. The module guarantees reliable treatment, even in contexts where requirements fluctuate rapidly from one cycle to another.

The Lavasonic HI also stands out for its quantifiable operational benefits. Processing times can be reduced by up to 40%, which can translate into increased throughput or reduced thermal load. The energy required for heating is reduced by up to 30%, while fresh water consumption can be lowered by around 20%. Overall, the machine's carbon footprint can be reduced by 35%. These improvements reinforce the relevance of this generation of washers in a context where environmental efficiency plays a central role.

The internal structure has been designed to minimise downtime. The circulation pumps, positioned horizontally in the scrubber, are more easily accessible for maintenance. In addition, a hygienic fresh water spray option can be integrated to increase microbiological safety and reduce maintenance requirements, particularly for areas exposed to sensitive residues.

A digital platform for real-time control

The Lavasonic HI is also part of the digital transition of industrial facilities. Equipped with an advanced touch interface and a modernised PLC control system, it allows process parameters to be quickly adjusted according to the level of contamination observed. Operators can select the appropriate programme in a matter of moments and immediately adjust the key factors of the washing process, such as the intensity of the ultrasound, the control of the high-intensity module and the internal circulation. This responsiveness supports consistent performance in a production environment where variability in returns is now the norm.
