General benefits

The dry ice is fed into a compressed air stream in a controlled manner. Due to the
enormously high speed that the air-ice mixture reaches in the jet nozzle, the dry ice hits
the contaminated surface, freezes the dirt and blasts it off the surface. The solid dry ice
sublimates in the process and becomes gas. The gas is non-toxic and neutral. The
removed dirt is carried away from the cleaned surface by the compressed air. It can then
be vacuumed, swept or filtered.
