Zerio AutoFog A-Series is a revolutionary Flash Corrosion Inhibitor (FCI) that diffuses in a matter of minutes to provide corrosion protection for bare metal surfaces. The rapid diffusing auto-fogging action allows corrosion inhibition of pipelines, voids and other enclosed spaces without the need for power sprays or fogging of powders.
The FCI action is especially important when welding shut voids and enclosed spaces where sweating due to trapped humidity inside the void can cause immediate corrosion.
Zerion AutoFog is ideally suited for prevention of corrosion in large metal voids and enclosures. AutoFog is especially effective when these enclosures contain pipelines, interstices, recesses, etc. which are difficult or impossible to access. AutoFog is an inexpensive and easy-to-implement alternative to Nitrogen purging in most cases. Typical applications include:
Voids and Enclosed Spaces:
Zerion AutoFog diffusers can be placed inside a void or enclosure before it is welded shut or sealed. They can be fixed in place with a wire mesh basket. In certain applications the diffuser packaging may be slit and the Zerion powder poured into the void to provide protection.
The asset to be preserved should first be cleaned and then enclosed. The enclosure could be either a containment packaging of Zerust corrosion inhibiting film or an integral self-sealing piece of equipment. Zerion AutoFog diffusers are then placed inside a void or enclosure before it is sealed.
*Zerion AutoFog A-Series is light tan, off-white powder in a breathable sachet contained in an outer leakproof bag.
