ADVANTAGES

Free of Chlorides: PRO Sorb contains no lithium chloride, a potentially harmful chemical for many metals. This salt can be transferred to metals in dusts or by human touch. PRO Sorb consists of 97% SiO2 and 3%Al2O3.

Low Abrasion: PRO Sorb beads produce less dust than other silica gels (abrasion <0.05 weight,—% according to MIL-D).

High Bulk Density: 1 kg PRO Sorb only needs a volume of ca.1.51, much less than some other silica gels.

Long Term Stability: PRO Sorb maintains the greater part of its capacity well beyond 2— 5 years, when other silica gels have lost a large portion of their capacity.

Economical: PRO Sorb is much cheaper than the other products sold for the same purpose.

Temperature Dependency: PRO Sorb is conditioned in relation to temperature. PRO Sorb reacts in the same way as organic materials do. Therefore there will be no, or little transfer of water vapour between organic materials and PRO Sorb if the temperature changes. Under fluctuating temperatures this property protects wood and other organic materials from swelling or shrinking. The conditioning indicated on the labels refers to 20°C. At 10°C the conditioning of the cassettes will be around 1-1.5% RH lower, at 30°C around 1-1.5% RH higher.

PRO Sorb Cassettes are much easier to handle than beads. They don’t need trays or containers and are exchanged quickly. Re-conditioning to their original RH value can be done easily by weight within the first 1-2 years. After a longer period of time, due to the slow degradation shown by all types of silica gel, conditioning must be checked with a calibrated hygrometer. The cassettes consist of PET and vapour permeable TYVEK non-woven. They are filled with PRO Sorb beads. Full size and half size cassettes are available. Full size cassettes: Content: 950 g beads. One or more cassettes per cubic metre of air volume are required depending on circumstances of application. Half-size cassettes: Content 500g beads. One half size cassette will be sufficient for 0.7m3 depending on circumstances of application. Beads and cassettes can be ordered without supplement at 40%, 45%, 50%,55% or 60% RH — please indicate when ordering. If no conditioning is specified, the standard is RH 50%. The conditioning refers to 20°C, with a tolerance of ±2%RH.
