Industrial cleaning with high pressure
High-pressure water cleaning is the most effective technique for removing scale, paint, mineral residues
and stubborn grease from industrial equipment and surfaces. With pressures up to 2,500 bar, the water jet fragments contaminants without aggressive chemicals and minimizes downtime.
What is high-pressure cleaning?
Industrial high-pressure water (HPW) cleaning uses piston pumps to generate water jets exceeding 250 bar. At ultra-high pressures (UHP > 1700 bar), the water acts as a hydraulic scalpel, removing layers of rust, varnishes, and hard deposits without contaminating the substrate.
Hydrodynamic principle
The impact of the jet causes micro-fractures in the contaminant layer, and the tangential force drags away detached particles. The rapid expansion of the water upon impact generates shock waves that separate the dirt from the base surface.
Advantages for the industry
- Removes layers up to 10mm thick in a single pass
- Dust-free and abrasive-free process: reduces waste management cuts.
- Compatible with carbon steel, stainless steel, concrete, and composites.
- Ideal for maintaining exchangers, pipes, and large surfaces.
- Complies with environmental regulations by avoiding shot blasting and solvents.
