Maintaining stable environmental conditions is essential for preserving valuable collections and protecting irreplaceable artifacts. DriSteem provides humidification, dehumidification, and water treatment solutions that help museums, galleries, archives, and cultural institutions maintain precise humidity levels throughout exhibit spaces, storage areas, conservation labs, and special collections environments.
Fluctuations in humidity can cause wood, paper, textiles, paintings, and other sensitive materials to expand, contract, crack, warp, or deteriorate over time. By maintaining consistent relative humidity, museums can help preserve collection integrity, extend artifact life, and protect investments in cultural and historical preservation.
DriSteem solutions help museums achieve the stable environmental conditions needed to support long-term preservation while providing reliable, energy-efficient operation.
Issues caused by uncontrolled humidity
Humidity can cause wood to expand and contract, metals to rust and paint to peel if not controlled.
- Porous and fibrous materials like wood contract and expand as humidity levels fluctuate. In high levels of humidity, wood, which has been a material used by artists throughout the centuries, loses its strength and becomes very flexible, while in low levels of humidity, it may become stiff and brittle.
- In humid climates, the corrosion of metal artifacts is much more rapid and severe. Rust and other oxidizing-type corrosion reactions, as a general rule, will not occur when the RH is maintained at or below 40%.
- High levels of humidity encourage pests and support the growth of mold on paper, textiles, and parchment. Eradicate pests and stop the spread of mold spores by optimizing the relative humidity level.
Preserving and protecting an exhibit is a costly undertaking for museum owners, including the cost of insuring the collections.
- Coverage for damages due to temperature, heat, or humidity issues may be excluded from insurance policies. Although many exclusions are negotiable, in some situations, like lack of environmental control, the cost of coverage may be excessively high.
Illness and discomfort to staff, volunteers, and visitors.
- Dry indoor air not only causes discomfort for visitors, volunteers, and staff, but it also allows easier transmission of airborne viruses such as SARS-CoV-2 and seasonal influenza.
- There are real costs associated with health-related issues caused by dry air, including a higher occurrence of infections and increased rates of staff and volunteer absenteeism.
Are you already using relative humidity to protect your collection?
For best performance and highest efficiency, existing humidification systems should be checked to determine if any replacement parts are needed, if any other maintenance needs to be performed, and whether there is a software update available.
