ZERUST® Provides 2 Years of Corrosion Protection During Outdoor Storage

Problem

A global chemical and specialty materials company that engineers and manufactures large industrial chillers contacted ZERUST® as they were looking for a corrosion control company to assist with the corrosion protection of industrial chillers while they are stored outdoors for up to 2 years. The internal surfaces of the chillers were protected via nitrogen purge, but the external surface area also needed protection. The external surface area was composed of mixed metals, including carbon steel bolts that were the most susceptible to corrosion. Additionally, an electrical control box was attached to each chiller. The customer initially thought plain shrink film would provide sufficient corrosion protection on the external surface, and the desiccant would be enough to protect the electrical box.

Solution

After explaining the potential failures involved with using plain poly shrink film and desiccants for the protection of metals, the customer decided to try ZERUST® ICT®510-OPS Outdoor Preservation VCI Shrink Film, ZERUST® OPS Preservation Tape, Axxanol™ Spray-G, and VC2-2 Vapor Capsules. Next, Axxanol™ Spray-G was applied to the critical carbon steel components, and the Vapor Capsules were centrally placed inside the electrical boxes. Lastly, the OPS film was used to protect the exterior of each chiller, and the seams were covered in OPS Preservation Tape.
