Energy and resource efficiency as well as cost savings are among the driving topics for process optimization in the industry. When it comes to cleaning before painting or coating, the dry quattroClean technology from acp systems AG (Hall 3, Stand 3521) can be used to exploit significant efficiency and sustainability potential. The process uses recycled, liquid carbon dioxide as a cleaning medium, which is a by-product of chemical processes and energy generation from biomass. It is accelerated with compressed air and blasted onto the surface to be cleaned.
Rotating two-material ring nozzle for particulate contamination
Various solutions are available to suit the task at hand: When removing loosely adhering, particulate contamination, the newly developed rotary two-material ring nozzle enables a high surface performance with minimized carbon dioxide and compressed air consumption. The rotary unit can be equipped with several blades, the diameter and jet angle of which can be adjusted to suit the specific application. This means that even complex interior contours can be cleaned, for example.
quattroClean snow blasting technology for filmic contamination
If, in addition to particulate contamination, filmic contamination also needs to be removed reliably over the entire surface or partially, quattroClean snow blasting technology is the ideal solution. With this alternative, the liquid carbon dioxide is also fed through a patented, wear-free two-substance ring nozzle and expands into fine snow as it exits. This is bundled by a sheath jet of compressed air and directed at supersonic speed with precise focus onto the contamination to be removed. acp systems has developed the quattroClean power jet technology for the complete or partial removal of stubborn particulate and film contamination. Here, the liquid carbon dioxide is compressed into granular cleaning granulate in an integrated system and blasted onto the surface to be cleaned in an accelerated manner using compressed air. The usual external pellet production required for classic dry ice blasting is no longer necessary, meaning that a fully automated, uninterrupted cleaning process can be realized.
