Dry ice sandblasting
One of the disadvantages of sandblasting is the accumulation and removal of the abrasive waste material from the channel. Therefore, an alternative method that produces no abrasive residues was developed. The so called “Jetty Robot” system uses dry ice as an abrasive, and is predominantly used for the cleaning of air ventilation ducts ranging from DN 400 (16 in) to DN 1,300 (52 in).
