We offer water treatment service companies a line of Vapor phase Corrosion Inhibitor (VpCI) products to protect idle boilers, cooling water systems and related equipment.
Our Vapor phase Corrosion Inhibitors (VpCI) function by releasing or vaporizing into the air space of a system and bond to all metal surfaces to provide a protective film. This Cortec® based technology is suited for both dry lay-up and partially wet/flooded lay-up. Properly applied, the VpCI products can protect systems for up to two years. Anytime a boiler, cooling system or related equipment is non-operable for an extended period, is drained, or partially flooded, VpCI technology can be an excellent choice.
VpCI technology is particularly valuable in situations where equipment is taken offline but still requires reliable corrosion protection. In many facilities, boilers, cooling systems, and auxiliary equipment are periodically shut down due to seasonal demand changes, maintenance schedules, or operational interruptions. During these idle periods, internal metal surfaces become highly susceptible to corrosion, especially when systems cannot be fully dried or maintained under ideal lay-up conditions.
VpCI products provide an effective solution for protecting systems during both short-term and extended outages. They are commonly used when boilers are placed in lay-up, cooling towers are temporarily shut down, or systems are awaiting startup or commissioning. In cases where equipment is partially drained or remains in a wet or humid condition, vapor phase inhibitors offer an added layer of protection by reaching areas that traditional liquid treatments may not fully contact.
To achieve consistent results, proper application of VpCI technology is essential. System condition should be evaluated prior to treatment, as removing existing deposits or contaminants can improve inhibitor performance and surface coverage. Once applied, maintaining a sealed or controlled environment allows the vapor phase to distribute effectively and form a protective film across internal surfaces.
Dosage and product selection should be based on system volume, configuration, and lay-up duration. Dry lay-up and wet lay-up conditions may require different application approaches to ensure full system protection. With the right combination of product selection and application strategy, VpCI technology can provide reliable, long-term corrosion protection while simplifying lay-up procedures for water treatment professionals.
