Pink Indicating Type Gel Beads help the users to quickly determine whether the desiccant needs to be replaced or recharged. It provides a rapid detection method by changing color as it absorbs moisture and eventually saturates. This is mainly used in absorbing moisture from gas and air. This gives an easy visual indicator of when the gel has started to become saturated with moisture. Pink Indicating Type Gel Beads are also used to dry the air in industrial compressed air systems. Air from the compressor discharge flows through a bed of silica gel beads. The silica gel adsorbs moisture from the air, preventing damage at the point of use of the compressed air due to condensation or moisture.
