Humidity and Moisture Problems in Preservation and Storage

Dehumidifiers for Preservation and Storage

moisture control and Humidity Problems

As the weather warms so does the humidity. Often indoor humidity can be higher than it is outside. This can be caused by a variety of, or culmination of several factors. Poor ventilation, overworking AC with an inadequate outlet, walls or windows not properly sealed allowing moisture to invade.

Photograph and film storage and preservation


Many materials are more susceptible to moisture than they are to temperature. There is a direct correlation between high relative humidity (RH) and moisture damage to stored products.

Dehumidifiers Control Humidity and Moisture

Specialised climate conditions are required when storing organic materials. Humidity, temperature, and pollutants are important factors to consider when archiving.

It is commonly acknowledged by preservation experts, that inappropriate water vapour in the air is a real threat to the preservation of documents, artefacts, and relics. Once damaged, the items will never return to their former condition.

Paper with damage caused by moisture issues in storage

Paper is a fibrous product. Naturally hygroscopic and vulnerable to temperature and humidity changes. In attempt to reach a balance with its surroundings, paper collects and releases moisture, which can affect its shape, dimensions, strength, and performance. If the paper neither absorbs nor loses moisture, then it remains in its optimal state.

There is an easy solution that once set up, frees you from constantly monitoring your indoor climate. Many use heaters, however this is costly and increases your energy consumption considerably.  

Refrigerant or Desiccant Dehumidifier?

Depending on the room's natural climate, either a desiccant or refrigerant (mechanical) dehumidifier will create and maintain the ideal climate for your products.
