Library, Museum & Archive Dehumidification Systems
At Desert Aire, we pursue the mission of preserving your permanently valuable records, materials and archives with our dehumidification systems for museums, libraries and any other building storing archives.
Desert Aire’s dehumidification solutions help Libraries, Archives, Museums and Galleries prolong the lives of their records and materials by creating finely tuned indoor environments within buildings and repositories that are the perfect condition for whatever material is being stored.
Conventional air conditioning cools the air temperature, but fails to properly control humidity. Our energy-efficient museum, library and archive dehumidification systems remove excess moisture to protect the contents of libraries and archives from mold, mildew, yellowing, curling and more.
Additionally, when building codes require outside air, Desert Aire's dehumidifiers remove excess humidity and supply the air at the temperatures and humidity levels you specify.
Materials That Need Proper Dehumidification to be Preserved:
|Material Type||Relative Humidity|
|Most photographic materials||
|Teeth, bone and shell||30-55% (lower than 30% can result in mechanical damage)|
Stable pyrite and pyritic specimens
Unstable pyritic specimens
|Freeze dried specimens||<40%|
Unstable or corroding metal
|Naturally mummified animal remains||15-20%|
The relative humidity for most National Park System collections is 45 – 55% relative humidity, ideally ± 5% from the set point.
What Happens When Materials Aren't Stored in The Proper Humidity?
Archive environments with excessive relative humidity (above 65%) are subject to mold and/or swelling and deformation of organic materials, metal corrosion and increased pests.
Excessively dry conditions can cause drying of materials that results in shrinking and cracking in materials such as ivory, teeth or wood, and dehydration of some minerals.
Fluctuating humidity causes cycles of shrinking and swelling of organic materials and can potentially result in deformation or/and fractures, causing layered materials to delaminate and/or buckle, and loosening of joints of components.
Desert Aire has been providing commercial dehumidifier solutions since 1978 and have installations throughout North America. We look forward to assisting with your next project!
