The Cryoclean Snow cleaning system from Linde LLC uses compressed air and a high-pressure nozzle to eject a stream of carbon dioxide (CO2) dry ice particles and remove dirt and surface residues from plastic parts prior to painting.

The solvent-free, automated system is said to reduce energy usage and costs compared with aqueous and solvent-based cleaning systems. It also avoids handling issues associated with dry ice pellets and requires little maintenance, the company says. In addition, CO2 is inert, so there are no ozone-depleting solvents and no potential for oxidizing metal, and because the snow sublimates directly after use, there are no cleaning agent residues. Treated parts also are dry because the system doesn’t use water.
