Corrosion in cooling towers or air handling units is a problem that must be addressed in a timely manner to prevent serious problems developing with HVAC systems. If you choose to leave corrosion in your cooling tower untreated, then the corrosion will endanger the internal steel substrates, and as it progresses it will encourage the growth of micro-aquatic bacteria, including Legionella, Pseudomonas, Biofilm and similar contamination in the tower.
Why does corrosion occur?
The most common cause of corrosion is that the coating on the internal surfaces of the cooling tower has reached the end of its useful life and needs to be replaced. Sometimes it is the original infuse bonded powder coating that needs to be replaced, but in other cases, owners have had the cooling tower coated with an epoxy or with bitumen coating which lacks the right elongation properties or chemical resistance to cope with aggressive structures such as cooling towers.
Are there any other common problems with cooling towers?
One problem often experienced with cooling towers is the deterioration of the mastic between the joints. Over time, this mastic starts to lose elasticity, and the structure begins to leak. Only a quality cooling tower repair solution from a qualified expert offers a long-lasting solution to this problem. Don't try to effect a short-term repair. Look for a quality solution which offers a guarantee on all completed work.
