Kinetic energy
The process incorporates high velocity (supersonic) nozzles for surface preparation and coating removal. Since kinetic impact force is the product of pellet mass and velocity over time, the delivery system achieves maximum impact force from a solid CO2 pellet at the highest velocities achieved.
Even at high impact speeds and direct impacts, the kinetic effect of solid CO2 pellets is minimal compared to other methods. This is due to the relative fluidity of solid CO2, which is not as dense and solid as other consumable media. Also, pellets change phase from solid to gas almost instantly upon impact,
- which effectively provides an almost non-existent coefficient of recovery in the impact equation. Very little impact energy is transferred to the coating or surface, so the dry ice cleaning process is considered non-abrasive.
