Dry Ice Blasting

Dry ice blasting is a process whereby kinetic and thermal energy is transferred when the accelerated dry ice pellets strike the surface being cleaned. Dry ice and air combine to remove the unwanted material and leave a clean surface free of any contaminant.

1. Kinetic Effect

2. Thermal Effect

3. Sublimation

4. After Blasting

Dry ice pellets are accelerated by compressed air to high speeds, fracturing the top layer of dirt and residue. The thermal difference helps to separate the dirt and residue from the substrate.

After the dry ice makes its initial impact, it instantaneously turns from a solid to a gas. The volume expansion (by a factor of 700) causes a micro explosion that detaches the dirt/residue from the substrate. The substrate is clean, dry and completely intact. We supply the 3mm pellets that you need for this process.

The process of Dry Ice Blasting uses ice pellets to remove unwanted debris, it is not harmful to the substrate being cleaned or to the environment. Dry Ice Supply Dry Ice Blasting pellets are able to remove most graffiti within one session of cleaning. And because it leaves a completely dry, odourless surface, it is ideal for the interiors of buildings as well!
