Dry Lay Up Products Oil Additives Corrosion Control Water Treatment Corrosion Control
Cooling Towers and Boiler Seasonal Lay Up
In this day of modern technology most cooling towers are laid up dry. Towers and/or boilers are drained out to avoid water freezing in the system. Big and small water treatment companies usually treat cooling water, for a cooling tower, through out the year. When it comes to seasonal lay-up, most conventional methods do not provide the advantages of VCI Corrosion Protection.
Our VCI Lay Up Products Are
Corrosion Prevention Problem:Conventional seasonal lay-up programs often use an oil-based product that does not apply evenly; they can cause significant gunk balls in the equipment and oil products can be a challenge for disposal. This practice is environmentally difficult. Another problem with using oil-based products is that they may react with polymers in the water system or with other materials. Oil-based products van be a source of nutrients for various kinds of bacteria, including anaerobic bacteria. This leads to promoting microbiological growth in the water system and hence bacterial corrosion. The major shortcoming of conventional lay-up products is that they are strictly contact corrosion inhibitors (CCI*). A Contact Corrosion Inhibitor protects only the parts of the system that comes into direct contact with the corrosion preventative. The overhead spaces, crevices and other hard to reach volumes that do not have direct contact with the CCI may be left unprotected. These parts of the system tend to corrode during the down time because they lack lack corrosion and rust protection. Due to all of the above reasons it becomes important that a thorough cleaning of the system, using additional chemicals, is scheduled before commissioning the water system back into production when using conventional layup methods. Corrosion Protection Solution:A systematic and easy approach to lay-up of water systems during down time utilizing an environmentally safe, inexpensive and easy to apply VCI Corrosion Protection that is typically superior to conventional methods of oil-based products in water systems. These products will eliminate the use of hazardous chemicals for this process. VCI Powders & VCI LIQUIDS are two products that contain VCI. (Vapor Corrosion Inhibitor) VCI powders can be applied by 'dry fog' and they are also water-soluble materials perfect for seasonal or long-term lay-ups. VCI consist of blend of compounds that volatilize and create a VCI environment in the system. VCIs are adsorbed onto the metal surfaces forming a monomolecular layer. These protect both the anode and cathode sites of the metal surface. VCI Liquids are added to water and applied by circulating, spray or 'wet fogging'. Compared to conventional corrosion inhibitors, additionally provide: Vapor Phase Corrosion Inhibitors VCIs protect metals both in the in liquid contact state* AND in the vapor state* AND the interface of water and vapor, to protect surfaces in contact with air.*CCIs = Contact Corrosion Inhibitors require direct contact with metal to be effective*STATE = The physical state of the water molecule. i.e.. Solid, Liquid or GasA systematic VCI approach enables VCIs to protect even small crevices from corrosion. Our VCI water system products are multi-metal formulations that protect various metals including galvanized steel. Click here to see How VCI's WorkMethod of application:Dry Lay-up:

Summary:VCI Corrosion Protection Products Provide:
There are many opportunities to improve cooling tower system efficiency through the use of chemical treatments. Protecting a cooling tower properly during a lay-up period is an important aspect of cooling tower operation. It can improve efficiency of the system during the operation and save the maintenance engineer time and money if applied properly.
