Dry ice pellets have been used for cleaning for more than 30 years. Their acceptance in production and maintenance is quite unsatisfactory, due to the complex logistics involved and the high price of the dry ice pellets. In addition to the high investment and operating costs and the susceptibility of the blasting equipment to malfunctions, many sensitive components such as conveyor belts, switch cabinets, plastic parts and polished tools have also been damaged. Although dry ice blasting has many advantages over conventional cleaning methods, the disadvantages in terms of occupational safety and handling are of great importance for many companies. CO2 snow blasting is significantly more flexible and cost-effective. CO2 pellets and electric power supply are not required to operate the CO2 snow blasting machines. The power supply is provided by compressed air and liquid CO2 from single cylinders or bundles, each with a dip tube. A CO2 tank can also be installed for stationary applications. CO2 snow blasting is used in particular for sensitive surfaces and automated applications.
