Winter layup is a perilous time for cooling systems: Cooling towers and pipes that are shut down risk severe corrosion. This can take a toll during spring startup. Flaking metal and chip scale from rusting interiors can plug equipment, interrupt operation and even cause asset failure — despite traditional corrosion-inhibiting treatments.
Vapor-phase corrosion inhibitors (VpCIs) help protect systems in both wet and dry layup. These treatments are effective and may be safer than traditional corrosion inhibitors. They offer the flexibility of continued use after startup and during operation.
