The VCI Emitter is a lightweight disk that contains corrosion inhibitors to provide a corrosion-free environment. The corrosion inhibitor adheres to the metal surfaces, preventing the settling of salt, dirt, moisture, oxygen, and other contaminants from settling on the metal surfaces. Designed to be slim and compact, this allows the emitter to access tight and restricted spaces. Adhesive tape allows VCI Emitters to stay firmly on metal surfaces, walls, and cabinets. The unique nature of the corrosion inhibitor is formulated for steel and multi-metal parts. Capable of providing lasting protection for years even in humid conditions, the VCI Emitters are safe, easy to use, and economical.
