The disclosure relates to an apparatus for sterilizing a sealed enclosure (1 ) comprising a fan (8) for circulating a gas through a preparation circuit (11 ) and through the enclosure. The preparation circuit includes an evaporation chamber (10) for dispensing a decontaminant gas and water vapour mixture int o the circulating gas to flow therewith through the enclosure and to reach a concentration in the enclosure above the dew point for the ambient temperatu re in the enclosure and thereby to condense onto surfaces in the enclosure to sterilise such surfaces. A monitor (15) measures gas temperature and dew point/condensation are monitored (17, 18) in the enclosure and the resulting signals led to a control module (19) for controlling the rate of dispensing of the decontaminant gas and water vapour into the gas in the preparation circu it in response to the levels determined by said monitoring to provide a require d level of condensation of the decontaminant gas and water vapour in the enclosure.
