PTC Emitters are breathable pouches that contain Migrating Corrosion Inhibitor (MCI) powder. They can be placed in any void space enclosure where corrosion protection is needed. The MCIs vaporize through the pores of the pouch, diffuse throughout the space, and finally form a protective molecular layer on surrounding metal surfaces. Distribution of the MCI vapors in large spaces can be enhanced by blowing dry air through the pouches, if needed.
Adaptable to Protect:
- Tubular structures, pipes, and vessels
- Segmental concrete bridge tendons/cables
- Reinforcement inside box girder segments
PTC Emitters were initially designed to mitigate corrosion on suspension bridge cables. These cables are made of many metal strands twisted together with voids that can capture moisture and foster corrosion between the strands. Dehumidification systems are sometimes used to force dry air through these cables in an effort to reduce moisture and stave off corrosion. PTC Emitters are a perfect backup to the deficiencies of dehumidification. They can be easily placed in chambers added to the dehumidification piping for the purpose of blowing Migrating Corrosion Inhibitors throughout the intricacies of the suspension cable strands.
