This is a non-used untill now method for cleaning surfaces from mechanic and organic unwanted materials. This newest development is used in more and more countries and areas. It is a method that uses small size pellets of dry ice shooting them out of a jet nozzle with compressed air. This causes the surface unwanted material to shrink and loose adhesion from its base.

This method was applied in the early 70-th years from the engineer Kalvin Fong, who was trying to improve the parameters of the airplanes engines. The technology was a priority of the company Lockheet-Martin and Boing for a long time. Because of the dry ice unlimited opportunity, after 1987 year the cleaning technology is in large usage.

The use of carbon dioxide (CO2 ) industrial cleaning has taken on major significance. Since the development of dense dry ice pellets that are shot at high speeds against surfaces to be cleaned. The CO2 dry ice pellet cleaning creates and delivers a high velocity stream of non-toxite, non-harardous, non-explosive, dence CO2 pellets that travel at a very high speed per second. Upon impact, the dry ice pellets sublimate to a harmless gaseous state, leaving the surface cleane, dry and undamaged, while keeping the area free from secondary waste and debris.

When the jet of dry ice passes through the material, it comes in contact with the underlying surface causing some of the dry ice to convert back into carbon dioxide gas.

RADICALLY ADVANTAGES OF THAT SYSTEM

• much befter that cleaning by hand;
• reduce the cleaning time;
• cleaning the surfaces with dry ice leaves them cleane without damages;
• free from use of hazardous and chemical solvents;
• the equipment is easy for use and transport. Whitout usage of exterior energy supply;
• without secondary waste;
• the main components as CO2 and compressed air are part of the ecology cycle.
