Dry ice blasting is environmentally friendly, cost efficient, high-speed and an effective High Pressure Cleaning Solution.

What is Dry Ice Blasting?

Dry Ice is the solid form of pure carbon dioxide.  Dry Ice Blasting uses small dry ice pellets as the blasting media – and they are made from 100% carbon dioxide (Co2).

The dry ice pellets are formed by a machine that cleans the Co2 and turns them into 3mm pellets. The pellets are then injected into the high-pressure blasting machine and combined with compressed air – similar to other high-pressure blasting cleaning methods.

There are a few events happening when the Co2 pellets are blasted:

• Thermal – the extremely low temp. of the dry ice (-79c) shock freezes the contaminant making it brittle and weak.
• Kinetic – the bond between the contaminant and the surface that is being cleaned is loosening and cracking.
• Sublimation – the dry ice then penetrates the contaminant and instantly changes from a solid to gaseous state – sublimates – which lifts the contaminant from the surface

Fast & effective

Dry ice blasting machines have exceptionally high cleaning speeds, and can get deep into the nooks and crannies, of even the most inaccessible parts of what is being cleaned. The residue does not become trapped and no chemicals or materials are left behind – unlike other high-pressure cleaning methods.

For this reason, dry ice blasting is ideal for cleaning machinery, electrical installations, surfaces and moulds. Machines can often be cleaned while still in operation – eliminating the need for dismantling and re-assembling the machine in question.

Environmentally friendly

High-pressure dry ice is completely non-toxic. and requires no hazardous chemicals or solvents. It eliminates the risk of operators being exposed to hazardous fumes during cleaning.

The quantity of waste material is greatly reduced – with only the waste that has been blasted needing to be cleaned up afterwards. Costs associated with the disposal of hazardous solvents and chemicals is also eliminated – as well as the risk of polluting drains and sewerage systems.

Dry ice blasting is suitable for a large range of industries and functions.Dry Ice Blasting is ideal for removing coatings such as varnish, grease, oil, adhesives – just to name a few. They are ideal for industries that require high level of hygiene – such as pharmaceutical and food industries.
