Dry Ice Blasting
The usage of small dry-ice pellets has proven to be an excellent opportunity for cleaning various surfaces. In comparison to the usage of water, sand or synthetic materials, dry ice as a means of blasting device does not leave any kinds of remains. Carbon Dioxide volatilises without residue, moreover it is non-toxic as well as odour- and tasteless and therefore particularly suitable for effectively cleaning heavily dirty industrial facilities and machines during maintenance. As a results, dry ice blasting is not only highly ecological but also preserves the treated surfaces and your very own resources. Thus, dry ice blasting is most suitable for all kinds of applications as we will happily point out to you in a personal conversation.

A preserving process with extraordinary results
The dry ice blasting is based on pneumatic processes: fine dry-ice-pellets, with a diameter of about 3mm and a temperature of -79°C, are blasted with high speed on the surface to be cleaned. During the impact the kinetic energy of the dry ice particles is transmitted to the layers of soil, which leads to an efficient abrasion. Nonetheless, dry ice is a rather soft blasting material, which in fact cleans the soiled surfaces but does not work abrasively. Another big advantage is the complete evaporation of the dry ice after the impact - in specialist jargon called sublimation.
Thermal effects – thorough cleaning
This so called sublimation heavily cools down the treated surface which results in thermal shock and a shear stress: the layers of dirt cool down more heavily than the underlying surface, contract and, as a result, become brittle. Consequently, the thermoelectric voltage cleans layers of soil from the surface. The continuous high speed blasting eventually removes all remaining particles of dirt. Certainly, both the level of soling and the surface’s material do influence the efficiency of the cleaning process. Scientifically speaking, particularly the microscopic shock waves that are initiated because of the change of the aggregate state (from solid dry ice to gaseous CO2) during the impact ensure the efficient cleaning of the treated surface.
Dry-ice-blasting without any remains or moisture
Even the sublimation of dry ice does not lead to any remains or all kinds of moisture, what especially qualifies the dry ice blasting process for the thorough cleaning of electrical components. Regarding safety precautions our processes can also be used in sterile and highly sensitive facilities such as laboratories or hospitals. In contrast to cleaning processes based on sand or water, the dry ice blasting does not leave any remains behind apart from the treated layers of soil, as a common room temperature leads to the fast sublimation of the used carbon dioxide.
