ABSTRACT:
For sterilizing a tight enclosure (10) equipped with a ventilation and filtration circuit (14), said enclosure is isolated and the internal relative humidity level is lowered by means of an assembly (50) incorporating a drying cartridge (54). The sterilizing agent (46) is then introduced through a closed circuit (30) until a relative humidity level close to the dew point is obtained. The sterilizing agent is kept in the enclosure for a given contact time, before scavenging said agent by means of the ventilation and filtration circuit (14).
