Definition - What does Desiccant Cartridge mean?
Desiccant cartridges are cartridges widely used for products and instruments that are sensitive to moisture and humid environmental conditions. These cartridges provide protection against moisture-related issues for a wide range of applications such as containers, cases, and electrical and optical devices. Desiccant cartridges have a molecular sieve fill or a silica gel fill.
Corrosionpedia explains Desiccant Cartridge
Some products such as hybrid roofing elastomers are stored in containers or drums that protect the elastomers from moisture. Desiccant cartridges are added before sealing the container's top cap. When the container's contents have been used, the desiccant cartridge can be used in another container. Cartridges can be transferred from container to container until the cartridge's color indicates that replacement is required.
