Art Sorb

This desiccant controls relative humidity level around artwork and artefacts to prevent deterioration in art pieces.

A humidity controller is specially designed for artwork, artefacts & cultural assets; Humidity Controller is a moisture-sensitive silica material that adsorbs and desorbs moisture to maintain constant humidity in a sealed environment. Climatic changes in temperature and humidity can degrade pieces of art and historical artefacts over time, causing colour fading, cracking, and deformation. Although air conditioning mitigates the effects of heat and humidity, a stable microclimate is still required to preserve your artworks and artefacts. Humidity Controller minimises the deterioration of fine pieces of art and history from climatic fluctuations, protecting your heritage items for future generations.

Art Sorb Humidity Controller vs Silica Gel 

Ordinary silica desiccants only take in moisture, resulting in an overly dry environment that is not optimal for precious artworks. Able to react fast enough to humidity changes, Humidity Controller provides precise humidity control in environments between 40 – 70% relative humidity.


Humidity Controller can be used in display cases and performs best when it is airtight. When there is a heat source, use a heat shield to block the light or place it outside the box. This humidity controller must have adequate air contact to be effective while being airtight and has to be spread out evenly. It must not be in contact with the artefact.

Depending on the environment, the longevity of the Humidity Controller is practical for about five years. However, it will require humidification during the period. On average, it requires humidification after two to three years, making it a great reusable product. Furthermore, a hygrometer can be used to check for dehumidification. 

  • Works well with artefacts and arts
  • Lasts for a lengthy period of 5 years and needs to be re humidified after 3 years
  • Maintains relative humidity between 40%-70%
