As a primary desiccant or blended with other desiccants in any application where visual control of moisture is required, such as compressed air dryers, gas drying, breathers, for protection of non-consumable packaged goods, drying and storage of flowers and seeds, etc.
Silica gel products are widely used in retail applications, added to the packaging of everything from electronics to medicines to absorb moisture. Desiccant packets containing blue indicating silica gel are also utilized in compressed air systems. It is possible to prevent mechanical failures due to moisture buildup by circulating the compressed air through a silica gel packet, so that the moisture in it is adsorbed. This technique can be used in railway locomotives, as well as in industrial settings. Compressed air systems with moisture absorbers are used in conjunction with high-frequency satellite and radio transmission systems, too, to prevent radio signals from weakening.
