Alternatives for traditional cleaning
Dry-ice blasting
Dry-ice blasting is at the core competence of DELETE. It is based on the particle method and can be used instead of, for example, water, steel bead or chemical washing. The dry-ice method is best suited for fragile surfaces and targets that are easily damaged or vulnerable to water.
Dry-ice blasting is a so-called dry washing method; no water or detergent is used. Dry-ice blasting does not require water or detergent, and the dry ice itself sublimates during the process. Waste may nevertheless be generated from the material removed from the surface. It can remove soot, bitumen, grease and other deposits, depending on the surface and contamination.
The method can be used for cleaning paper and printing machines, different production equipment and machinery, silos, transformers, electrical equipment, etc., as well as for removing paint.
Glass-bead blasting
DELETE has extensive experience in glass-bead blasting. The glass bead method is suited for cleaning the turbines of power plants and other high-precision cleaning. Glass-bead blasting can be used to remove deposits such as iron and lime while limiting damage to suitable surfaces.
One of the benefits of bead blasting is that unlike sand or silica, the round glass beads to not block the potential cracks in the target.
In bead blasting, the glass beads are mixed with water in a wet blasting pressure vessel where the mixture is pressurised and fed into the nozzle through a hose. Due to the precise output and adjustments of the system, 0.5–4 bar will suffice as the blasting pressure. The glass bead mixture can be utilised more than once, which saves time and costs.
