System and method for controlling humidity in a cryogenic aerosol spray cleaning system

摘要

Humidity within the workspace of a cryogenic aerosol spray cleaning system is controlled by circulating the workspace atmosphere through a dehumidifier. Advantageously, the need for purging of the workspace atmosphere prior to each cleaning cycle is eliminated. A system and method are thereby provided for cleaning of large workspaces. The system amd method of the invention are especially well-suited, economical, and practical for cleaning operations in which a dry air or inert gas purge of a large volume cleaning chamber would be impractical.
