The Gel 1kg desiccant is a powerful container desiccant. Using a calcium chloride and starch mixture each 1kg bag can capture 3 litres of moisture. Calcium chloride is a hygroscopic salt able to attract and bind large volumes of water. Moisture is captured in the form of a gel, an irreversible reaction eliminating any possibility of leakage. Easy to install, the Absorb King features a hook enabling the unit to be hung discretely around the container walls.
