Moisture Control Solutions for Document Storage

Moisture control is a critical factor in preserving documents, especially for libraries, archives, museums, and record-keeping institutions. High humidity can lead to mold growth on documents, causing irreversible damage. This article explores the role of dehumidifiers in document storage.
Why is Document Storage Important?
Protecting Document Quality: Properly preserved documents retain their original appearance and avoid deterioration or decay. For essential materials such as financial records, contracts, and confidential data, maintaining the quality of documents is crucial for safeguarding valuable information. Effective storage also helps eliminate health risks for users.
Enhancing Work Efficiency: Neatly and systematically organized documents make retrieval easier. This is especially beneficial for research-related materials, aiding in the study of history, culture, economics, and society.
Paper documents turn yellow when not stored properly
Ensuring Continuity: Document storage is vital for passing down and building upon the achievements of previous generations.
Supporting Policy Planning: Document preservation is a fundamental task that serves as a foundation for governmental and organizational control, management, and the development of plans and social projects.
The Impact of Humidity on Document Storage
Mold Growth: Vietnam’s tropical monsoon climate results in consistently high humidity levels, typically around 80%, and even higher during the rainy season. When humidity exceeds 60%, mold begins to form, damaging paper, photographs, and other materials, and producing unpleasant odors.
Paintings are adversely affected by high humidity
Fading and Warping: Ink and paint used on books, documents, and artworks are susceptible to fading or smudging in high humidity, leading to loss of content. Moreover, paper can become warped or decay when exposed to excessive moisture.
Corrosion: Many documents and images contain metallic elements that are highly prone to corrosion in humid conditions, leading to severe damage.
Books are deformed by high humidity
Paper-based materials, such as books, newspapers, photographs, and artwork, are highly hygroscopic, making them vulnerable to deformation and damage. Therefore, preserving paper materials is particularly critical for important documents, books, and images housed in museums, tax departments, and archival centers. Different types of materials require different levels of humidity for optimal preservation, specifically:
Document type | Safe humidity |
Paper documents, manuscripts | 40-55% |
Documents made of papier-mâché | 40-55% |
All kinds of movies and tapes | 40-60% |
Black and white photo | 20-30% |
Documents made of leather/parchment | 55-65% |
Lacquer painting | 50-60% |
Picture on canvas | 35-50% |
Picture /papyrus | 35-55% |
With these humidity levels, the best way to preserve them from mold is to use devices that can adjust humidity as required. This will help ensure quality archived documents with standard humidity levels while also keeping the storage space dry.
Dehumidifiers – Optimal Humidity Control for Document Storage
Dehumidifiers are known for their role in humidity control across warehouses and their applications in drying processes. They are also an ideal choice for handling moisture issues in document storage at museums, libraries, archives, and similar facilities, offering numerous practical benefits:
Maintain Appropriate Humidity Levels
The optimal humidity range for document storage typically falls between 45% and 55%. Dehumidifiers help maintain stable humidity levels, minimizing the risk of mold growth and issues related to document deformation.
Prevent Damage from Humidity
High humidity can cause paper to decay or warp, while low humidity makes paper brittle and prone to cracking. Dehumidifiers maintain a balanced humidity level, protecting paper and other stored materials from damage. Beyond paper, materials like wood are also highly sensitive to moisture and require appropriate humidity for preservation.
Protect Machinery and Equipment
Modern storage facilities often include equipment like scanners, electronic document readers, and digital preservation devices. These machines must operate in dry conditions to ensure efficiency and longevity. Dehumidifiers not only protect documents but also help maintain the lifespan of these devices.
Ensure Human Health
In museums, libraries, and document storage offices, high humidity not only affects documents and equipment but also impacts the health of staff and visitors. With dehumidifiers, the space becomes safer, healthier, and more comfortable.
