Silica gel desiccants remove moisture from the air by adsorption. Their performance in tough conditions can be lower than other desiccants. Silica gel is usually granules or beads Some grains may contain small amounts of indicator substance that changes color when they have absorbed some water. Silica gel is also used to dry the air in industrial compressed air systems. Air from the compressor discharge flows through a bed of silica gel beads.
