What is Dry Ice Blasting ?
Dry Ice Blasting is similar to sand blasting, bead blasting or soda blasting, where 3 mm dry ice pellets are accelerated in a pressurised air stream to impact the surface to be cleaned. Once in contact with the surface, the dry ice evaporates. This process is called sublimation and is a unique characteristic of dry ice, which makes it ideal for cleaning a variety of industrial equipment in the automotive industry.
HOW MUCH AIR IS REQUIRED?
A typical plant air system of 6 - 12 bar with a minimum of 180 cfm is sufficient. The size of the supply line must be a minimum of 25 mm (1”)
Dry Ice International is the supplier of the locally designed and manufactured Brilliant BlasterTM, as well as supplier of Europe’s best available blasting equipment. Visit our website for more information.
DRY ICE STORAGE
Dry ice pellets are delivered in specially designed dry ice polystyrene containers. Depending on climatic conditions, the pellets will last four to six days in this container.
Dry Ice International carries out deliveries countrywide on a 24-48 hour basis. Dry ice may be ordered on our website and be delivered to your doorstep. Dry ice can also be collected at any of our retail outlets.
PROFESSIONAL DRY ICE BLASTING SERVICE
We have well trained professional teams that do the dry ice cleaning of welding fixtures or tyre moulds on site on behalf of our customers on a daily or weekly basis. These teams are lead by professional artisans. From our experience we have seen improvement of downtime of more than 80% in some cases!

HOW DOES IT WORK?
Unlike other blast media, dry ice is frozen carbon dioxide (CO2) at a temperature of -78.5 °C. Dry ice blasting utilities 3 mm dry ice pellets, which are accelerated in a pressurized air stream and subsequently directed at the surface to be cleaned. The dry ice freezes the dirt on impact, then rapidly sublimates while the CO2 gas removes the frozen dirt without causing damage or abrasion to the surface. Because of the temperature difference between the dry ice particles and the surface being treated, thermal shock occurs during the process. This causes a breakdown of the bond between the two dissimilar materials. The dry ice pellets are accelerated up to 300 m/s by the compressed air and then blasted onto the surface to be cleaned. The second part of the cleaning process is the impact of the kinetic energy.
REASONS WHY YOU SHOULD CONSIDER DRY ICE BLASTING
- Eliminates equipment damage, as a result of zero abrasion.
- Increased safety: the process is dry, non toxic, non-abrasive and is suitable for use on welding fixtures and tyre moulds.
- A faster, more thorough clean, including complicated cavities where typical grit blast media will become trapped.
- Reduce or eliminate the use of permanent blast media, solvents, acids or chemical detergents.
- Reduce waste disposal and is more environmentally friendly.
- Decreased down-time, increased productivity and bottom line savings.
