Cortec Provides a Solution for Corrosion Protection During Dry Layup of Cooling Systems
To effectively protect cooling systems from corrosion during dry layup, Cortec has developed Cooling Tower Frog, which features Vapor phase Corrosion Inhibitors packaged in polyvinyl-alcohol water-soluble bags.
With fall and winter on their way in many parts of the world, maintenance engineers will soon be thinking about shutting down cooling systems for the season. Since winter often brings subzero temperatures, this means water treatment professionals often must drain the water to prevent freezing.
To effectively protect cooling systems against corrosion problems from clogging, leakage, or system failures that can increase downtime and repair costs, and lead to shortened equipment service life, Cortec has developed Cooling Tower Frog®, which provides an added layer of corrosion protection.
Although specifically designed for seasonal, short-term, or long-term dry layup of cooling tower systems, Cooling Tower Frog® can also be used for protection of closed loops.
Cooling Tower Frog® protects multi-metals in enclosed spaces through the use of Vapor phase Corrosion Inhibitors packaged in polyvinyl-alcohol (PVA) water-soluble bags. When these bags are slit open, the corrosion inhibitors vaporize and disperse throughout the enclosed system, forming a strong, self-replenishing protective molecular layer on all metal surfaces, including recessed areas and interior cavities.
Cooling Tower Frog® is easy to apply, reduces chemical consumption and cost, and avoids direct worker contact with chemicals. Little or no surface preparation is necessary.
How Cooling Tower Frog® worksAfter the cooling tower or closed loop has been drained according to normal layup procedures, workers simply have to slit open the water-soluble bags and place them flat inside the equipment, making sure all internal spaces are closed off from the outside atmosphere.
Two bags treat over 1,000 gallons (3,800 L or 3.8 m3) of enclosed space.
At the end of layup, the Cooling Tower Frog® does not have to be removed, as it dissolves in the makeup water as the system refills.
