Cooling towers are generally the greatest option for powerful, industry-grade temperature management. These specialist heat exchangers use modern water-cooling methods to keep your systems cool in even the most demanding applications. Unfortunately, because cooling towers regulate temperature with water, they are vulnerable to contamination and maintenance concerns, necessitating regular water treatment to remain functioning.
However, any water purification procedure will not suffice. The majority of cooling tower issues are caused by ultra-fine particle that gradually coalesces in the water of your cooling tower over time. These impurities must be handled with and correctly removed on a regular basis, or your cooling towers will have performance and efficiency concerns, eventually causing your system to fail.
What makes ultra-fine particles risky?
Cooling towers cleanse various impurities that are present in your airstreams as they attempt to keep your systems cool. The contaminants wind up in the cooling tower's water supply, where they will remain until the water is appropriately treated or replaced. Even with the latter, some particle can be difficult to remove because it adheres to the impellers, pumps, and other internal components of the tower.
The harder it is to remove fine particles, the more difficult it is. Due to their increased surface areas, ultra-fine particulate, especially those in the submicron range, can more easily cling to and become stuck in the inner components of your cooling tower, causing larger and larger problems over time as that particulate accumulates.
This is especially problematic for your tower's heat transmission surfaces. Particle accumulation obstructs surface heat exchange, resulting in severe performance and efficiency losses.
What Are the Most Common Cooling Tower Issues?
One of the most serious problems with ultra-fine particulates extends beyond the immediate harm that these particles can inflict. Ultra-fine particles can cause a slew of additional serious cooling tower issues, such as:
1: Biofilm and fouling:As your cooling tower runs, contaminants from the outside air will be drawn in. This comprises microbiological deposits such as fungi, algae, and bacteria, which can form a slime or "biofilm" on the heat transmission surfaces of your cooling tower. Fouling and cooling inefficiencies result as a result of this. As the biofilm grows, it has the ability to weigh down the structural parts of your tower, causing serious structural damage.
Inorganic ultra-fine particulate build-up can help microbiological deposits form by providing a better surface for them to adhere to, which can exacerbate the problem if ultra-fine particulate is not filtered out. Biocides and other essential water treatment chemicals can be harmed by ultra-fine particles, making biofilm and fouling more difficult to regulate. Furthermore, some organic deposits fall into the ultra-fine size category.
2: Scaling and corrosion: Corrosion is inevitable when water comes into touch with metal. Cooling towers, in particular, are prone to corrosion when compared to other industrial equipment. Corrosion on the inside components of your cooling tower can also be caused by ultra-fine particles and biofilm, laying the framework for scale.
Scale can be caused by calcium sulphate, calcium phosphate, and other calcium salts that your tower picks up from the air. Scale affects the performance and efficiency of your tower by dampening its heat transfer surfaces, similar to biofilm and ultra-fine particulate build-up.
3: Foaming:Excessive foam can cause the sump in the tower to overflow or force the fans to evacuate foam. Fouling can also occur because foam has greater levels of microbial pollutants.
Once any of these issues arise, you'll find yourself in a vicious cycle of cooling tower issues, as each one adds to and builds upon the others. Regardless of the sort of cooling tower you have, they all use comparable water-cooling technologies, making these difficulties a major source of frustration for everybody who owns one.
