MOISTURE STABILIZER - PROSORB

Prosorb Moisture Stabilizer Description

The Prosorb moisture stabilizer allows you to control humidity by keeping it at a certain desired value between 30 and 60% relative humidity. Due to its large internal surface and its ability to absorb and release water vapor from the environment, Prosorb can maintain a stable relative humidity. The entire humidity stabilization process is carried out without sudden changes in humidity.

Depending on the climatic conditions that are drier or wetter than the desired humidity range, the PRO SORB preconditioning will need to be adjusted to the upper or lower end of the desired RH range.

As already mentioned, the Prosorb moisture stabilizer allows the humidity to be regulated between the ranges of 30% and 60% relative humidity, ideal for maintaining collections in museums since the relative humidity for conservation is usually within this range. Therefore, it responds precisely to the needs of museum curators.

It is an ideal product for the transport and storage of products that need to be kept in a controlled humidity between certain values, being able to act without changing it for several months. It is capable of absorbing a quantity of water, within the range already mentioned, superior to other moisture stabilizing products, reaching a water absorption of 22.6% by weight.

Available in two formats: large cassette 950g and medium cassette 500g.

The dimensions of the large 950g cassette are 333 x 110 x 43 mm and the dimensions of the medium 500g cassette are 333 x 110 x 24 mm.

Applications

Prosorb moisture stabilizers can be used in all those closed spaces where humidity must be kept stable, without fluctuations. Some of the most common applications are the following ones:

• Conservation Sector Works of Art and Cultural Assets: Allows active climate control
• Pharmaceutical industry
• Capital Goods Sector
• High value-added freight transport
• Military industry
• Construction

It is a very versatile range of products that can adapt to different applications through their various forms of supply (cassette, bulk, bags or panels).

Prosorb Specifications

Some characteristics of the product are:

• It is recommended to use between 2 and 4 kg for each cubic meter of volume. The amount required is increased if there are entrances and movements of air in the cabinets, if there is a very large difference in humidity between that inside the cabinets and the exterior, if it is a question of long-term exposures or if there are temperature fluctuations.
• The different Prosorb products can be reconditioned for reuse, simply by adding or removing excess or missing water. This reconditioning process must be done inside a plastic bag following the manufacturer’s instructions.
• Prosorb products have a useful life of between 10 and 20 years, depending on the materials with which they are stored. It is recommended to store the moisture stabilizer in aluminum bags to avoid water vapor permeability.
