Dry ice blasting

Applications in Technical Projects

  • Surface cleanings (stone, wood, marble)
  • GRAFFITI removal
  • Rehabilitation from natural disasters

Dry ice blasting is an innovative industrial cleaning method with a broad range of applications in engineering projects. It is widely used in cleaning marble, stone, wooden or other surfaces from a broad range of contaminants such as oils, glue, rust, paint as well as in the rehabilitation of natural disasters.  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
