Dry ice cleaning

The principle of dry ice cleaning:

When cleaning with dry ice, dry ice particles are used as a blasting medium. With the help of the dry ice blasting system COOLMASTER® these particles are being accelerated to an extremely high speed by compressed air and then are blasted onto the object to be cleaned through a nozzle.

This produces 3 effects which, when combined, enable an optimum cleaning process:

1. The kinetic effect: the dry ice particles being accelerated to high speed.

2. The thermal effect: the dry ice particles hit the dirt layer at -78.5° C, cool it down abruptly, it contracts and forms cracks. Due to the different coefficients of thermal expansion, the compound between the surface and the dirt is loosened.

3. The sublimation: on impact, the carbon dioxide directly transforms from a solid to a gaseous state and expands about 700 times the volume in a split second. This expansion literally ”blasts off” the dirt from the surface. As a result, only the dissolved dirt particles remain at the end of the cleaning process and can be easily disposed of.
