Cooling Tower Repair Solutions
Cooling Tower Repair Solutions - A cooling tower is a prime target for corrosion as it is almost constantly exposed to moisture increasing its corrosion potential.
Most towers are constructed from galvanized sheet metal. The galvanizing [or factory-installed anti-corrosion coatings] last about as long as the manufacturer’s warranty.
ENECON coatings provide a robust anti-corrosion coating, as well as non-corrosive polymer paste repairs to seams and corrosion holes that develop over time.
- CHEMCLAD GP - General Purpose High Performance Polymer Composite Coating System for Industrial/Commercial Applications In Standard Chemical Environments
- CHEMCLAD SC is a two component, 100% solids, polymer system used for creating an outstanding corrosion and chemical resistant protective coating on all types of potable water equipment and structures.
- DurAlloy is a two-component, 100% solids, multi-purpose polymer composite which can be easily machined on a lathe, drilled, tapped, filed, sanded and polished.
Case Study
Above is a typical “before” picture of a Marley cooling tower. The supports for the return screen are rusting out, and there is corrosion everywhere.
“After” ENECON CHEMCLAD GP has been applied. There is long-term corrosion protection to all surfaces. The picture does not tell the complete story. A similar-looking picture could be made from applying a simple rust-resisting paint. However, paint would result in a coating system of about 4 mils thick. The ENECON system results of a strong, 2-part polymer coating of 12-20 mils. Thickness is life!
Another Example:
May 2006 – a tower leaking so badly that they have a hose from the building almost constantly adding water to keep operating. Here's why...
Grit blasting surface preparation reveals hundreds of holes, from pea to nickel size.
ENECON’s METALCLAD DurAlloy™ applied to seal all holes.
Followed by two coats of CHEMCLAD SC.
RESULT – This work was completed in May 2006. The tower remained in service [with no need for a water hose!] until May of 2013, when it was replaced due to mechanical/motor/fill failures unrelated to corrosion.
