Protection of Electrical Controls

Zerust Vapor Capsules are portable capsules that contain patented Zerust VCI technology. Use to protect metals in hard to reach areas of control panels, electrical cabinets, and other enclosed spaces, even when they are in operation. Use Vapor Capsules to protect multiple metal types from corrosion in almost any enclosure or sealed packaging. Zerust diffusers emit Vapor Corrosion Inhibitors (VCIs) that prevent oxidation of the metal surface that causes rust. They provide targeted corrosion protection in hard to reach spaces and additional protection to metals in Zerust VCI packaging applications. Zerust capsules are quick and easy to install. Simply peel back the protective paper from the adhesive tape and install securely in the desired location. Tightly seal the enclosure to trap protective vapor inside. Metals will be protected from rust and tarnish for up to one or two years depending on the capsule model and environment.


Problems caused by electrical equipment corrosion include resistivity changes and intermittent contact failures in critical alarm and control functions, added local heating and power loss in critical components, solderability issues for circuit boards, changing the calibration of analog meters and, ultimately the integrity of cabinets are compromised.


The specific solution recommended for electronics and electrical control boxes is NTIC’s line of Zerust ICT® Vapor Capsules. These capsules are available in various sizes to suit multiple applications Zerust ICT Vapor Capsules are easily installed in a matter of seconds without tools or specialized labor.
