Dry ice cleaning - dry ice blasting

What is dry ice?

Dry ice is the term used for frozen, solidified carbon dioxide (CO2) with a temperature of -78.5°C. In its gaseous state, carbon dioxide is a normal part of our atmosphere. It is thus obtained from natural sources and turned from liquid form into pellets in a special process (using a pelletiser).

Where do you get dry ice?

Commercial dry ice pellets with a diameter of 3 mm can be obtained from the worldwide dry ice supply network.
The pellets are supplied in special thermal boxes and can be stored in them for several days.

Advantages of dry ice cleaning?

• Clean and residue-free - when they hit the surface to be cleaned, the pellets sublimate and revert directly to the gaseous state. Neither moisture nor blasting agent residues are created in this process.
  
  
• Effective- The dry ice pellets are accelerated to supersonic speed and produce lots of mini-explosions (impact energy) which releases the unwanted substance from the substrate (thermal energy) without damaging it (non-abrasive).
  
  
• Safe- Dry ice blasting is non-conductive. As a result, even live components can be cleaned directly (e.g. control cabinets, engine parts, etc.)
  
  
• Environmentally friendly- There are no residues left behind. Cleaning without chemical additives. Furthermore, dry ice is non-toxic, non-flammable, tasteless, odourless and bacteriological.

THE PROCEDURE:

In principle, dry ice blasting equipment is similar to sandblasting equipment. However, dry ice pellets are used as the blasting medium. These are accelerated in the dry ice blasting machine to extremely high speeds with a jet of compressed air and directed onto the item being cleaned through a blasting hose and gun. Because of the resulting mini-explosions and the resulting cold shock (-78.5°C), dirt particles are released from the substrate.
