Dry ice blasting

Dry ice blasting is an innovative industrial cleaning method with a broad range of applications within the industrial sector. It is widely used in cleaning surfaces from oils, glue, rust, paint and other contaminants. At a first glance, dry ice blasting seems identical to abrasive blasting techniques. However, dry ice, as opposed to sand or other abrasive media has a much lower density/hardness and is able to remove contaminants without harming the substrate material.

Due to the special characteristics of the media used (solid CO2), dry ice blasting employs a totally different operating principle. The sudden temperature differential causes bond failure of contaminants, whereas the instantaneous sublimation of dry ice during impact creates a lifting force that removes them. Some of the most prominent advantages of dry ice blasting over other cleaning methods include the following:

  • Dry ice is nonabrasive, nontoxic and nonflammable
  • Fast and efficient cleaning without having to move/disassemble the equipment
  • Causes no harm to substrate material
  • Can be applied to any surface
  • Absence of secondary contaminants since dry ice sublimates after impact
  • It is environmentally friendly since there is no use of chemical additives
