Dry ice blasting uses compressed air to accelerate frozen carbon dioxide (CO2) pellets to a high velocity. A compressed air supply of up to 16 Bar (80 PSI/50 scfm) can be used in this process.
Dry ice pellets can be made on-site or supplied.
Carbon dioxide in all its states is non-poisonous. Dry ice is recycled carbon dioxide, which is both inexpensive and can be easily stored at work sites.
Instead of using hard abrasive media to impact and damage a surface, the dry ice blasting method uses dry ice pellets, accelerated to a high velocity, which then collide with the target surface.
Harnessing the power of the kinetic energy and rapid change of state causes a so called “thermal shock”, propelling the undesirable contamination off the underlying target surface.
