1. How does CRYONOMIC® Equipment accomplish cleaning?
Small dry ice pellets are accelerated through one of a variety of cleaning nozzles, using compressed air variable in pressure up to 230 psi.
When the pellets hit the surface to be cleaned, their kinetic energy causes them to penetrate to the base material, at which point they shatter, blasting fragments laterally in all directions, releasing the contaminant from the base material.
Instantaneously, the dry ice fragments sublime, i.e. turn directly from solid to gas. The expansion of the CO2 from solid to gas adds a lifting force "MUSHROOM EFFECT" to speed removal of the contaminant.
The debris falls away, and the CO2 gas returns harmlessly to the atmosphere.
