ABSTRACT:
A recirculation/drying unit is provided for connection to a sealable enclosure. The unit and the enclosure form a closed circuit through which the gaseous medium of the enclosure is circulated, filtered, dehumidified or optionally, humidified, and returned to the enclosure. A vapor decontaminant is carried into and through the enclosure by the gaseous medium for a predetermined period of time sufficient to sterilize, disinfect or sanitize the gaseous medium, the enclosure and its contents. The decontaminant is returned to the unit for conversion into a form suitable for release into the atmosphere. The unit preferably includes filters, an air pump, a drier, a reservoir of liquid decontaminant, a reservoir of water, an injection pump, at least one vaporizer and at least one converter.
