Function - The Basics
 The method in brief

Blasting methods such as sand blasting for remove paint, dirt, grease and similar coatings from surfaces are well known. The industry is using dry ice pellets for many years as an effective blasting agent. The main advantage of this cleaning method is that the dry ice pellets sublime completely after blasting. Only the removed soiling remains. This makes dry ice blasting a particularly effective, environmentally friendly cleaning method, which is not abrasive to the materials to be cleaned.

 What is Dry Ice?

The blasting agent which consists of dry ice is the solid form of CO2 (carbon dioxide) at a temperature of -79C. The carbon dioxide is an odourless, non-toxic gas which is used in the drinks industry as an additive in beer and mineral water, for instance. The addition of carbon dioxide means the fresh taste and the shelf life of the drinks can be guaranteed for longer. It is also used in the food industry for cooling meat and sau-sages.

 How is Dry Ice Produced? 

Liquid carbon dioxide is directed from a low-pressure storage  CO2 Tank into a special machine the Pelletizer , and depres-surised using a dispenser valve. This procedure forms dry ice snow at a temperature of -79C. The interactive piston in the pelletizer presses the dry ice snow through a die to form, dense Dry Ice Pellets the size of grains of rice (3 mm).O2

 Where do you get Dry Ice Pellets from?

The easiest way is to produce dry ice pellets yourself with the DIS Dry Ice Systems pelletizer. If your requirement is low, dry ice is available from gas suppliers nationwide and can be stored for around seven days in special insulated boxes. Simply request our list of suppliers.
