Vapour Phase Corrosion Emitters Explained…

Vapour Phase Corrosion Emitters

Vapour Phase Corrosion Emitters Vapour phase corrosion emitters are small, specialised devices designed to provide corrosion protection for metal components and parts which are enclosed in non-ventilated control boxes. The Vapour phase Corrosion Inhibitor (VpCI) emits vapours that form a monomolecular protective coating on internal metal surfaces. This coating protects critical, complex and expensive electronic equipment from corrosion initiation during operation, shipping or storage.

Three products from Cortec provide long term protection against corrosion in the presence of adverse conditions including salt, moisture, airborne contaminants, H2S, SO2, NH3, and others. These products all provide a similar level of protection.

VpCI-101 is a small patented device from which Vapour phase Corrosion Inhibitors are slowly released.
VpCI-105 & VpCI-111 are small patented plastic emitters with a breathable Tyvek® membrane through which corrosion inhibitors are slowly released.

  • VpCI-101 will protect cabinets or tool boxes of up to 1 cubic foot (28 litres).
  • VpCI-105 will protect cabinets or tool boxes of up to 5 cubic feet (142 litres).
  • VpCI-111 will protect cabinets or tool boxes up to 11 cubic feet (312 litres).

Vapour Phase Corrosion Emitters - Easy To Install

VpCI emitters are simple and convenient to install. The devices should be installed at the earliest possible time, preferably during manufacturing or assembly.

To install, simply select a space within an enclosure where corrosion protection would be useful. Ensure that the surface to which the device will be affixed is clean and free of debris. Using the adhesive tape at the bottom of the device, affix the device to the clean surface.

For volumes greater than the emitter size, multiple devices may be used. If the enclosure is not totally airtight or if the access doors are opened frequently, replace the emitters more often than every 2 years. After periods of heavy maintenance replace the device.
