The VpCI-101 (Vapor Phase Corrosion Inhibitor) device is designed to provide anti-corrosion protection for metal parts and components located in unventilated control boxes, furniture or tool boxes. A VpCI-101 device protects up to 28 liters in volume. VpCI-101 is a small, patented device that releases Vapor Phase Corrosion Inhibitors (VpCIs). VpCI emits vapors that form a molecular film on metal surfaces to protect critical, complex, and expensive electronic equipment and other metal components during handling, shipping, or storage. VpCI-101 provides long-term protection against corrosion even in harsh conditions including salty, humid, airborne pollutants, H2S, SO2, NH3, and others.
