Art Sorb

A Humidity Controller is specially designed for artwork, artifacts & cultural assets. It is a moisture-sensitive silica material that adsorbs and desorbs moisture to maintain constant humidity in a sealed environment. Art Sorb can sustain a stable high relative humidity due to its vast interior surface and ability to absorb and emit water vapor from the surroundings. It also has lithium chloride as an additive, which allows it to reduce humidity in high-humidity conditions. The entire humidification procedure is completed without any abrupt fluctuations in moisture levels.

Climatic changes in temperature and humidity can degrade pieces of art and historical artifacts 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 artworks and artifacts. The Humidity Controller minimizes fine art pieces’ deterioration and history from climatic fluctuations, protecting 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, the Art Sorb Humidity Controller provides precise humidity control in environments between 40 – 70% relative humidity.

Applications

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

Depending on the environment, the longevity of the Art Sorb 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 is 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%
