UHP Technology

The FineJets technology used for manual or automatic cleaning tools fragments the impact force required for the process into a multitude of jets with extremely high kinetic energy and minimal mass.

Nozzles with extremely small orifices, even as small as 0.08 mm, allow for supersonic water speeds (at 2300 bar, the water speed is 2.5 times the speed of sound). Very limited amounts of water are typically sufficient for good efficiency.

The nozzles are mounted on rotating heads that differ in imprint diameter and number of jets. The assembly also includes specific inclinations for each jet and rotations on different orbits.

Rotation is ensured by high-torque pneumatic motors integrated into the tools, allowing for the selection of the correct speed based on the process.

This setup produces a circular imprint with extremely high pressure and high rotational speed, which, with variable angles, effectively removes coatings or process residues.

The UHP water technology offers many benefits compared to conventional surface removal and restoration processes. First of all, the use of only water represents an extremely eco-friendly, environmentally compatible, and highly respectful choice for the environment.

The possibilities for using UHP technology with only water are countless, with a multitude of different application sectors and in non-binding environmental conditions.

For residues resulting from manual or automatic process operations, it is sufficient to collect the debris in simple bags or filtration systems.

The use of water also ensures the possibility of normal channeling and collecting 100% of the removed material. Typically, it is sufficient to apply a treatment with an appropriate filtration and retention level, allowing the water to be discharged directly into the network. The filtered water in some cases can be reused directly in the process.

In other cases, for continuous cycle reuse, a second and specific treatment is necessary (dedicated Airmation systems for multi-stage filtration and retention).

As for other types of residues, the systems typically leave nothing in the air, neither suspensions nor debris that could be transported.

The most common traditional removal technologies typically involve the use of chemical products or baths, abrasives, and in some cases, mechanical removal with tools.

Chemistry is slow and costly in terms of overall management and safety, and very expensive from an environmental perspective and for the work environment itself. It can also create latent incompatibilities and unclear results, especially in the subsequent processes the product is intended for.

The use of water free from chemicals ensures the treated surface is clean and residue-free, allowing for reproducibility of results.

The use of abrasives, generally faster than chemical processes, is also expensive due to the need for disposal, containment, and collection of the abrasives. Additionally, the environment usually needs to be controlled because of the significant dust and gas in the air. The surface cleaned using only water ensures a very deep clean, without inclusions or sediments between the micro-ridges of the surface, allowing for better adhesion of coatings, making them more durable.

Even with mechanical removal using tools, there is usually a need to reprepare the product with new sandblasting and/or grinding. In both cases (sandblasting and mechanical removal), it becomes impossible to differentiate between the coating to be removed and the substrate; typically, these methods also remove the substrate, often excessively.
