Prosorb Humidity Control Panels (customisable)
Prosorb Humidity Control Panels (customisable)
To stabilize the relative humidity in painting frames and flat showcases. Price calculation depending on dimensions.
PROSORB is the proven silica gel for stabilizing the relative humidity (RH) in museum showcases. PROSORB can adsorb and release a large amount of water vapor between 30% and 60% RH. The humidity range for artworks made of organic materials is kept as constant as possible with PROSORB and moisture fluctuations are buffered. PROSORB will be delivered adjusted to the desired humidity value.
PROSORB panels are being used for very flat applications such as painting showcases.
Custom made panels: up to 800 x 1150 mm, special shapes possible
Thickness : 10 or 20 mm
Material : polypropylene honeycomb panel, polyester fleece, Marvelseal 360; alternatively: polyester fleece on both sides
Packing: aluminium barrier film
Application example: microclimateclimate frames for paintings
The 10 mm thick panels are filled with approx. 3.5 kg PROSORB / m². Total weight approx. 5 - 5.5 kg / m² depending on conditioning.
The 20 mm thick panels are filled with approx. 7.5 kg PROSORB / m². Total weight approx. 10.5 - 12 kg / m² depending on conditioning.
The fleece laminated honeycomb panels were Oddy-tested in 2011 and are suitable for permanent use in museum showcases. The aluminum composite film Marvelseal is sealed without additional materials. The edges are reinforced with 3M # 425 soft aluminum tape, also Oddy tested.

How much PRO SORB do I need?
The amount of PRO SORB that you need depends on a variety of factors. These include the tightness of the display case and the ambient climate. It is therefore diffi cult to make predictions. Basically, the more PRO SORB is used, the lower the fluctuations in humidity and the less frequently the display case will require maintenance. We recommend beginning with 2 - 4 kg of PRO SORB per cubic metre of display case volume and constantly monitoring the RH in each display case with a hygrometer.
Guideline values are:
- 2 kg/m³ for glass hood or large display cases > 2 m³
- 4 kg/m³ for very tall or small display cases (< 0.2 m³)
The amount required increases with:
- leakages in the display case,
- high moisture gradients between the display case and the ambient air,
- ong exhibition durations or permanent exhibitions,
- temperature fluctuations and air movements,
- hygroscopic display case installations that are drier or damper than the desired climatic range. The exhibits themselves may sometimes be drier or damper than stated by the lender.
