Zerust^® ActivDri^™ Capsule protects ferrous and aluminum metals in enclosed spaces. It utilizes Vapor Corrosion Inhibitors (VCI) to prevent corrosion and silica-gel desiccant to combat humidity that affects metals and electronics. It is designed to protect large voids inside of critical items during shipping and storage.

The ActivDri Capsule features a durable coated steel cable to aid inserting and retrieving the unit from the center of a void space. The cable is affixed to the capsule in multiple points to provide a secure hold. When the protected item is ready for service or final assembly, simply remove the capsule.

Use ActivDri to protect electronics, equipment and assets in corrosive environments such as in salty air, sewage treatment plants or power plants. ActivDri corrosion inhibitors form an invisible shield that provides powerful corrosion protection. The capsule reduces flash-rust and corrosion incidents, even in contaminated and challenging environments.

Do not place capsule in direct contact with yellow metals and test before use with copper and brass.

*Specifications are rated for an airtight enclosure with a relative humidity level of less than 40%. For more humid, contaminated and/or frequently accessed enclosures, use multiple capsules or replace more often.
