Cultural Heritage

EXPERIENCE SINCE 1970 IN THE DESIGN AND CONSTRUCTION OF VACUUM SYSTEMS FOR THE CULTURAL HERITAGE SECTOR.

Basi’s experience in lyophilization allows the implementation of this process with specific functionalites in the field of cultural heritage restoration.

Lyophilization is the only technological process authorized by MiBACT (Italian Ministry of Cultural Heritage and Activities and Tourism) for the drying of archival and library heritages. It is a dessication process by which a soacked support, generally because of water, is preventively freezing and then being subjected to high-vacuum application; in this way, the liquid immediately switch from solid phase to the gaseous one, through sublimation. Brizio Basi is leader in this technology.

Lyophilization has the advantage, compared to air drying, to reduce for approximately 75% time and materials to be used, minimizing the solubilization of inks and the creation of stains. Moreover, the chemical-physical materials charateristics remain unaltered, since the process occurs at a below -20°C temperature.
