Dry ice: gentle and effective at the same time
Fine dry ice granulate is blown onto the surface to be cleaned at high speed. Dirt (grease, release agents, coatings) become hard and brittle due to the cold (-79 degrees Celsius) and flake off.
Dry ice is CO2 (carbon dioxide) in solidified form. CO2 is an odorless, non-toxic gas. In the beverage industry, for example, it is added to beer and mineral water in order to keep the fresh taste longer and to extend the shelf life. CO2 is also used in the food industry or in airplanes: Here it is used to cool meat and sausage products.
Production: Liquid carbon dioxide is fed from a tank into a special machine and relaxed. This creates dry ice. This medium at a temperature of -78.5 ° C is then pressed through a die - the result: dry ice pellets the size of a grain of rice (about 1.3 or 3.0 mm).
The paintwork and the original underbody protection are retained (provided that the paintwork or underbody protection is not loose, for example if it is infiltrated by rust);
Electrical and fuel lines are not damaged and therefore do not have to be removed;
The ice-cold pellets sublimate completely after blasting, ie they completely dissolve in gas and go back into the atmosphere from which they were originally obtained. Only the removed dirt remains - this significantly reduces waste and saves time.
If you, too, want to clean your vehicle's underbody with dry ice: Contact us - we can usually offer you appointments at short notice. You should expect a treatment time of five hours or more, depending on the degree of contamination.
After cleaning, we offer (if required) a thorough underbody preservation (transparent) or the treatment of rust spots in the underbody area.
Dry ice is frozen CO2 and is around -80 ° C cold - it is absolutely environmentally neutral, non-toxic and contains no water. For cleaning, dry ice is pressed into rice grain-sized pellets and applied to the surface to be cleaned with dry ice cleaning machines.
Due to the cold and the high speed of the dry ice pellets, the dirt becomes brittle and cracks - the surface to be cleaned is not attacked because dry ice is not abrasive.
Upon impact, the dry ice pellets increase their volume by 760 times and "blast" the dirt particles off the surface.
Dry ice changes directly from the solid to the gaseous state (sublimation) and dissolves without residue. There is no moisture during cleaning and no contamination from the blasting material.
