Humidity Controller Art Sorb


The Humidity Controller Art Sorb is made to protect artwork, cultural assets and artefacts from damage caused by climatic changes in temperature and humidity. These changes result in the pieces of arts and artefacts degrading over time, causing cracking, colour fading and deformation. The Humidity Controller ArtSorb, a moisture-sensitive silica material is hence, able to prevent the mentioned damages by adsorbing and desorbing moisture to create a constant optimal humidity in a sealed environment. Although air conditioning can prevent damage caused by humidity and heat, a stable microclimate is still necessary for the preservation of artworks and artefacts.

Humidity Controller Art Sorb vs Silica Gel

Regular Silica Gel is only capable of adsorbing moisture, leaving an arid environment that is not optimal for artworks. However, the Humidity Controller ArtSorb can react to the humidity changes, providing precise humidity control in environments between 40-70% relative humidity.


The Humidity Controller Artsorb is applicable in display cases and performs best when in an airtight environment. When a heat source such as light is present, use a heat shield to block the light or place the light outside the box. For the Humidity Controller to be effective, there must be adequate contact with air, be in an airtight environment and is spread out evenly. The Humidity Controller should also not be in touch with the artefact. Depending on the environment, the lifespan of the Humidity Controller ArtSorb typically lasts for about 5 years. However, during these 5 years, a process known as humidification is needed which takes place after two to three years after use. A hygrometer can be used to check for dehumidification.
