A high-pressure pump and additional spraying bars provide solvent-based cleaning at 10 bar to 16 bar pressures. The spray pressure is adjusted via a high-pressure pump controlled by variable-frequency drive (VFD). Pressure, spray duration, spraying mode (simultaneous or alternating), and product movement can be defined in a part-specific cleaning program and stored in the machine controller.
Throughout the process, the spray jet dislodges contaminants from the part surface, the high fluid exchange rate flushes away dislodged foreign matter, and injection flood washing is performed with more intense turbulences, improving cleaning.
For cleaning processes requiring only external spraying and/or no high-pressure application, the central spray bar can be removed.
