1.Kinetic Energy Transfer

Dry ice pellets are accelerated by compressed air to high speeds fracturing the top layer of dirt/residue.

2.Micro-Thermal Energy Transfer

The different materials contract unequally and the adherence between them decreases. This thermal difference helps to separate the dirt/residue from the substrate.

3.Sublimation Energy Transfer

After the dry ice makers 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.
