VpCI®-111 emitters are unique devices designed to provide corrosion protection for metal components and parts enclosed in non-ventilated control boxes, cabinets or tool boxes up to 11 cubic feet (312 liters).


The Vapor phase Corrosion Inhibitor (VpCI®) emits vapors, which form a molecular layer on internal metal surfaces to protect critical, complex, and expensive electronic equipment during operation, shipping, or storage. VpCI®-111 is patented with a breathable Tyvek® membrane cover through which corrosion inhibitors are slowly released. VpCI®-111 provides long term protection against corrosion even in the presence of adverse conditions including salt, moisture, airborne contaminants, H2S, SO2, NH3, and others.

VpCI®-111 is extremely simple and convenient to install. VpCI®- 111 emitters should be installed as early as possible, preferably during manufacturing or assembly. Simply select a space within enclosed device where corrosion protection would be useful. Verify that the surface on which the device will be installed is clean and free of debris. Peel off the protective peel strip from the bottom of the device and attach it to the clean surface. The peel strip can be separated to reveal a self-adhesive sticker on which the installation and replacement dates can be noted. VpCI®-111 emitters can be installed in any position. For volumes greater than 11ft3 (312 L), install more than one VpCI®-111. If the enclosure is not totally air-tight or if the access doors are opened frequently, replace the VpCI®-111 emitter more often than every two years. After periods of heavy maintenance, replace the emitter. For additional protection, spray the enclosure very lightly with ElectriCorr® VpCI®-238.
