We have compiled the answers to the most frequently asked questions about cleaning with dry ice and our dry ice blasting machines in Germany.
The dry ice is controlled in a controlled air stream. Due to the enormously high speed achieved by the air-ice mixture in the jet nozzle, the dry ice hits the contaminated surface, freezes the dirt and blows it off the surface. The solid dry ice evaporates and becomes gas. The gas is non-toxic and neutral. The removed dirt is carried away by the compressed air from the cleaned surface. The dirt can be sucked or filtered.
