Your Guide to Buying a Cooling Tower

Top 3 Essential Features of a Cooling Tower System Unit

May 30, 2019

Cooling towers vary a lot in terms of their features, making the buying process intimidating for many purchasers. While there are many decisions to make when choosing a cooling tower, there are three major factors that will narrow down your options to a much more manageable number.


Cooling Tower System Capacity and Performance

This is the headline specification for any cooling tower system, but different manufacturers measure it in different ways. Getting a large enough capacity is essential as returning overly warm water will prevent cooling equipment from working properly, and may even damage it.


The heat rejection capacity of a cooling tower system is often measured in tonnes. This measures the number of tons of ice that could be melted by the heat removed by the cooling tower over 24 hours. A cooling tower’s capacity is also often measured in terms of flow rate, which measures the amount of water that it can handle in gallons per minute. The capacity of your cooling towers needs to be enough to handle all of the water flowing through your cooling system.


A cooling tower’s performance is often measured by its approach. This is the difference between the output temperature of the water and the wet bulb temperature of the air used to cool the water. The other common measure of cooling performance is the range, which is the difference in temperature between the hot water entering the cooling tower and the cooler water exiting it.


Cooling Tower Size

Your cooling tower needs to fit into the space that you have set aside for it. Remember that not all locations will be suitable for a cooling tower as the air intakes should not be close to a structural wall, and the tower as a whole should not be near the building’s air intakes.


The cooling tower system’s footprint is very important no matter where you want to place the cooling tower. Height matters more for indoor cooling towers than outdoor ones, but care should be taken to ensure that the fan discharge is above the level of any nearby walls.


Cooling tower product users looking to save space often opt for counterflow cooling towers. These use pressurized nozzles to spray water vertically downwards through the cooling tower fins against an upwards flow of air. This type of cooling tower system can have a smaller footprint than a crossflow cooling tower system, but will be less energy efficient and require more regular servicing. They also have more limited maintenance access, making cleaning cooling tower basins more difficult.


Open Circuit or Closed Circuit?

Open circuit cooling towers pass water from the cooling system directly through the cooling tower, exposing it to outside air. Closed circuit cooling tower systems use a separate heat exchanger loop between the water circuit used to cool the building and the flow of air from outside.


Open circuit cooling towers are simpler designs and therefore tend to cost less up front. The simpler design also saves on space. On the other hand, they can allow contaminants from outside into the entire cooling circuit, so they may not be suitable for high-pollution areas.


In a closed circuit cooling tower, the cooling circuit water is kept inside a coil that is cooled by spraying it with water, keeping it separated from any outside air. This makes fouling less likely, meaning that cooling tower maintainers can use up less time cleaning cooling tower fins.

Preventing Disease From Cooling Towers

June 1, 2019

Moisture, warmth, and biofilm. A poorly maintained cooling tower is an ideal environment for disease-causing bacteria. Preventing disease from cooling towers is one of the most important health and safety priorities in any workplace environment.


How To Prevent Legionnaires’ Disease In Cooling Towers

Legionnaires’ disease is one of the primary disease risks associated with cooling towers. It is also one of the most serious, proving fatal in about 10 percent of cases. Having some level of Legionella inside a cooling tower is almost inevitable as they provide ideal conditions for the bacteria to grow and are open to the environment. Preventing Legionnaires’ disease from building up in cooling towers should be a key priority in cooling tower maintenance, and efforts made to tackle it will also prevent other cooling tower diseases.


What are the Origins of a Legionnaires Outbreak?

Many outbreaks of Legionnaires’ disease from cooling towers can be traced back to poorly maintained cooling towers dispersing Legionella bacteria through cooling systems in aerosolized water. Legionella bacteria live easily in warm water, meaning that even well-maintained cooling towers can have some level of infection. However, the problem of Legionella disease in cooling towers can get a lot worse if biofilm is allowed to build up inside, as this provides a great environment for bacteria to grow.


So, how to prevent Legionnaires’ disease from cooling towers? Preventing Legionella disease in cooling towers requires regular and thorough maintenance. Have your cooling tower inspected and cleaned at least twice a year, using biocides to prevent Legionnaires’ disease in the cooling tower. Biofilm should also be removed using chemical treatments as well as brushing or pressure washing.


How To Prevent Algae Growth In Cooling Towers

Diseases from cooling towers tend to start with bacteria breeding in biofilm. Biofilm is an ideal environment and food source for bacteria. Unchecked algae can form biofilms, making it that much easier for Legionella and other hazardous bacteria to colonize your cooling tower. It can also block proper water flow and allow pools of standing water to form, providing another friendly environment for harmful bacteria. However, algae also serves one useful purpose. Algae buildup is a visible sign that it is time to have your cooling tower cleaned, unlike bacteria which can live invisibly in cooling systems.


To prevent algae growth in cooling towers, you have a few options. Adding chlorine or other biocides to the water can help to prevent or slow down algae growth. Larger shock doses can help to clear more severe algae buildup. Different algaes will be best dealt with by different types of biocide, so having your water analyzed can help determine the right treatment package for your cooling system.


Physical cleaning is also required to clear up biofilm as well as scale and other issues. This gets rid of accumulated biofilm and gives maintenance experts a chance to inspect the tower for clogs, corrosion or damage.


How To Maintain a Cooling Tower For Disease Control

Add chlorine or another biocide to your cooling system water, making sure to use the appropriate amount and type for your system. Many cooling tower users accomplish this by adding an appropriate amount of commercial bleach.


Have your cooling towers cleaned regularly, at least twice a year as OSHA recommends. Keeping your cooling tower free of biofilm and scale deprives bacteria of the environment that they need to grow.


Make sure that your cooling system is well designed. Poorly designed cooling systems may allow areas of standing water to form, providing a great environment for Legionella and other bacteria.

Cooling tower cleaning and maintenance

Getting Cooling Tower Maintenance Right

June 15, 2019

A well-maintained cooling tower will keep your building cool and comfortable. A tower that doesn’t receive essential cooling tower maintenance can lead to spiraling electric bills, disease outbreaks, and potentially total failure of the tower itself. Getting maintenance now prevents these issues from occurring in the future. OSHA recommends thorough cleaning and inspection twice per year, but scheduling maintenance more often may be necessary if you notice issues building up.

Potential Cooling Tower Maintenance Issues

There are three main cooling tower maintenance issues: scale, biofilms, and corrosion. Your cooling tower cleaning checklist should aim to tackle all three. Scale is caused by hard water leaving hard deposits on cooling tower components. It reduces efficiency by clogging components and also provides a good surface for biofilm to grow on.

Biofilm is an accumulation of bacteria, biofilm, and other microorganisms that builds up inside cooling towers. It provides an ideal home for various disease-causing bacteria like Legionella, making biofilm buildup in cooling systems a serious health hazard. It is also a very effective insulator, which means that your cooling tower will become a lot less efficient at doing its job at cooling water. If you see your electrical bills starting to rise unexpectedly, biofilm might well be the culprit.

Finally, corrosion and other physical damage can seriously affect the functioning of your cooling tower or even make a complete replacement necessary. Your regular scheduled cooling tower maintenance should include a thorough visual inspection, possibly with photographic record taking to make it easier to track any issues as they build up.

Cooling Tower Cleaning Equipment and Supplies

Routine cooling tower maintenance usually begins with chemical treatments. Chemicals are used to break up and soften limescale deposits as well as to kill bacteria and soften biofilm. Foaming agents are often used as they get into small spaces that might not be accessible with a brush.

Once the deposits have been softened with cooling tower cleaning chemicals, they can be removed with brushes, hoses, or pressure washing equipment. Professional cleaners will often use specialized brushes and hose nozzles for cleaning different parts of the tower. Low powered pressure washing equipment is usually used as higher powered pressure washers can damage delicate components like cooling tower coils.

Many cooling tower maintenance providers also use cooling tower vacuums to clear contaminated water, biofilm and debris out of cooling towers. These specialized cooling tower cleaning tools are specifically designed to clean cooling towers effectively.

Preventive Cooling Tower Cleaning Methods

Adding biocides to your cooling tower water will help to kill off bacteria and prevent biofilm accumulation. Many cooling system owners use commercial bleach, but there are also other cooling tower cleaning chemicals available like chlorine gas and hypobromous acid.

When using these cooling tower chemicals, make sure to use the right amount for your cooling system and water chemistry, based on water analysis. Too much chlorine will damage your cooling system, while too little won’t be effective.

Protective cooling tower linings and coatings can help to prevent corrosion and biofilm buildup. Cooling tower cleaning services may be able to help apply protective coatings, so ask about preventive measures the next time you schedule cooling tower maintenance.

How Are Cooling Towers Built and How Do They Work?

June 28, 2019

Cooling towers are a very efficient way to remove waste heat from buildings. They are used to cool large buildings of all kinds including factories, shopping malls and office buildings. How cooling towers are built will depend a lot on the specific design, but all cooling towers use the flow of air to cool down the warm water circulating through the cooling system.


What Types Of Cooling Tower Are There?

Open circuit cooling towers - they use airflow to cool the warm water used in the cooling circuit. Closed circuit cooling towers use a heat exchanger coil between the warm water and the outside air. This is often how cooling towers work with a chiller, as it keeps any environmental debris out of the coolant.

Induced draft cooling towers - they use exhaust fans positioned at the top of the cooling tower to draw air through. Forced draft cooling towers use a fan at the intake to force air through the cooling tower. This allows for a smaller tower overall, but is less efficient and may cause air recirculation issues if the tower is poorly designed.

Crossflow towers - they use fans to direct airflow horizontally across the fill, cooling the water as it flows downwards. Counterflow towers draw air through vertically upwards, directly against the flow of water. This allows for a taller tower with a smaller footprint, making it a good option for some spaces. However, it requires pressurized nozzles to spray the water while a crossflow design can rely on gravity.

Splash fills - they are designed to break up the flow of water into droplets to increase its surface area for more efficient cooling. Film fills increase the water’s surface area by directing it to form very thin layers on sheets. Film fill cools the water more efficiently but contaminated water will leave residue on the sheets, requiring regular maintenance.

Although there are several options, how a cooling tower works is important when determining the cooling tower needed for your building.


How Are Cooling Towers Built?

Smaller cooling towers are often pre-assembled at the factory and shipped in as close to a finished state as possible with minimal on-site assembly required. This is typically how cooling towers are built for businesses with smaller cooling needs, although larger modular cooling towers can be shipped module by module.

So how are cooling towers built if you need a larger tower? Field-erected cooling towers are manufactured in pieces and then assembled on site. If the completed cooling tower wouldn’t fit on the back of a truck, it makes sense to assemble it on site instead. Manufacturers often provide the necessary labor, so the clients don’t necessarily need to know how cooling towers are built.


How Does a Cooling Tower Work In a Power Plant?

Many people have seen the large cooling towers used to cool power plants. These are very different in design to the cooling towers used to cool factories and office buildings. Instead of forcing air through the tower using fans, these natural draft cooling towers rely on the natural tendency of warm air to rise as it is less dense than cooler air. This allows airflow to be created entirely naturally, meaning that the running cost of one of these towers can be very low.

So how are cooling towers built to maximize natural draft? The main factor is that they have to be tall to create a large difference in air density between the top and bottom of the tower. Some of the largest ones are around 650 feet tall. Cooling towers this big have to be very strong and stable, which is why they have their distinctive inwardly curved shape. Their size also makes natural draft cooling towers totally impractical for anything except large power plants, oil refineries, and other huge industrial facilities. However, some hybrid cooling towers use fans to assist a natural draft, and these can be built somewhat smaller.

Why Cleaning Is Essential To Prevent Corrosion and Disease From Cooling Towers

April 1, 2019

Why do cooling towers need regular cleaning? Cleaning helps to tackle several important and often interrelated maintenance issues including corrosion, scale buildup and disease from cooling towers.


Regular Cleaning Prevents Disease From Cooling Towers

Cooling towers provide a warm, damp environment that is open to outside air. This makes them an ideal breeding ground for bacteria. Disease from cooling towers is a major occupational health hazard, with cooling tower Legionella outbreaks being a particularly serious problem. Legionella bacteria growing inside the cooling tower can dispersed through the entire cooling system, causing potentially fatal Legionnaires’ disease in people who breathe them in. This is why OSHA recommends cleaning and disinfecting twice a year for cooling tower Legionella prevention.


Property managers who want to reduce their cooling tower Legionella risk even further may want to consider using preventive biocides into their cooling water. Bacteria can recolonize a cooling tower very quickly after disinfection, either from outside air or the water supply or by surviving a less than thorough cleaning. Adding chlorine or one of the many non-oxidizing anti-bacterial agents available can suppress your cooling tower Legionella bacteria.


Cooling Tower Cleaning Removes Scale and Biofilm

Disease from cooling towers is probably the most serious issue that insufficient cleaning can cause, but it definitely isn’t the only one. Warm water leaves mineral deposits behind as it evaporates, forming scale. The harder the water is in your area, the worse this problem can become.


Scale buildup can restrict the flow of air or water through your cooling tower, making it work less efficiently and potentially stopping your cooling system from cooling your building enough. Adding scale inhibitors to your cooling water can help to reduce this, but the only way to get rid of scale entirely is to have it cleaned.


How Does Biofilm Affect Your Cooling Tower?

  1. Many of the bacteria found in biofilms will corrode metal, causing severe damage to your cooling tower if left unchecked.
  2. It provides a protective environment for bacteria, making biocides less effective and giving them room to grow and thrive. Many of the bacteria that cause diseases from cooling towers will have started life in biofilm.
  3. It makes the cooling tower run less efficiently. Even very thin layers of biofilm will trap heat effectively, making cooling much less energy efficient.
Biofilm is similar to scale in that it is a residue left on cooling tower surfaces. It is essentially a coating of slime made from colonies of bacteria that has all kinds of damaging effects on a cooling system.


Because biofilm resists biocides, specialized biodispersant chemicals are needed if you want to try a preventive approach. Even then, the only way to remove it entirely is through physical cleaning.


Removing Other Fouling

The bacteria and microalgae that form biofilms aren’t the only living things that can damage your cooling tower and prevent its proper functioning. Larger algae can form clumps or strands that clog pipes and choke strainers and fills.


While live algae will only grow in sunlight, dead and decomposing algae is a great food source for bacteria, so removing it still has a role to play in preventing disease from cooling towers. Mold is also a potential hazard in cooling towers thanks to the warm, damp environment found inside them.


Not all fouling is biological in origin either. Cooling towers are open to the atmosphere and so can let in all kinds of dust and debris, especially in relatively polluted areas.


Cooling Tower Inspections

Cooling tower cleaning companies don’t only remove scale and biofilm, they can also inspect the tower for any damage or corrosion. These are related problems: a corroded surface provides a great environment for biofilm to grow, making disease from cooling towers more likely. Damage to components can also allow areas of low flow to form, providing areas where biofilm and scale buildup is much more likely.


Because cleaners have to get inside your cooling tower and clean all surfaces thoroughly, your scheduled cleanings are a great opportunity to make sure that your cooling tower is working as it should.

What To Look For From Cooling Tower Cleaning Services

April 15, 2019

There are a lot of cooling tower cleaning services, so picking the right one isn’t always easy. Looking at just a few factors can help you to make an informed decision and get a cleaning service that meets your needs.


What is the Right Cooling Tower Cleaning Cost

It is important to choose a cooling tower cleaning service that falls within your budget. Some cooling tower cleaning companies, like Pinnacle Cooling Tower Service offer a free cooling tower inspection and estimate so you can find out what the cleaning will cost in advance. This is also a great opportunity to discuss any special requirements that you might have and find out more about the kinds of cleaning processes that they use.


When budgeting for cooling tower cleaning services, it is important to think of it as an investment. Replacing a cooling tower due to corrosion is costly, but even a less-than-thorough cleaning can be expensive in the long run. Biofilm, scale, and algae all reduce the efficiency of your cooling system by insulating heat and blocking pipes, making everything less energy-efficient. An outbreak of Legionnaires’ disease in your factory or office building can be even more costly.


When budgeting, you should also take into account how often you will be using the service. OSHA recommends chemical cleaning of cooling towers at least twice a year for disease control purposes. This is convenient as it means you can get a cooling tower cleaning service after turning your cooling system off for the winter and before turning it on for the summer. However, some towers may need a greater cooling tower cleaning frequency, especially in high pollution areas.


Get the Right Cooling Tower Cleaning Methods and Services

A thorough cooling tower service should include measures for controlling bacteria and algae, removing scale and biofilm and checking for corrosion or damage. A free inspection and estimate is a good opportunity to discuss how a cooling tower cleaning service tackles all of those problems.


Remember also that cooling tower cleaning companies do not necessarily only clean cooling towers. Depending on the company that you decide to go with, they may also offer other services like repairs, rebuilding, installation, or upgrades. Having a cooling tower cleaning company that can also take care of repairs and rebuilding is very convenient.


Read the Testimonials

Cooling tower maintenance requires experience and expertise, and those can be difficult things to judge from a website or advertisement. The problem is that a badly done cooling tower cleaning service can miss potential issues or even damage your tower. One great way to find the right cooling cleaning company for you is to look at their testimonials. A string of satisfied customers is a great sign that the company provides an excellent service. It may also help to look for reviews of the company on review sites or on social media.


Check the Service Area

Choose a cooling tower cleaning company that services towers in your area. For example, cooling tower cleaning companies in NYC don’t usually service cooling towers in Texas. Some cooling tower cleaning companies serve multiple states, though, so get in touch to find out whether they cover your area.

What To Expect From Cooling Tower Cleaning Companies

April 28, 2019

If it has been a while since your last cooling tower maintenance, you may be wondering what cooling tower cleaning services even do. Maintenance and cleaning companies like Pinnacle Cooling Tower Services can offer a range of services depending on what is most appropriate for your particular needs.


Cooling Tower Cleaning: Scope Of Work

A thorough cooling tower cleaning will aim to take care of several different maintenance issues that cooling towers often suffer from. Bacteria buildup inside a cooling tower is almost inevitable even if you use automated cooling tower cleaning systems and so any cleaning should include a thorough disinfectant treatment to tackle Legionella and other dangerous bacteria. OSHA cooling tower cleaning standards recommend disinfecting all cooling towers at least twice a year, as well as disinfecting before putting a new tower into use whether for the first time or after a long downtime. Cooling tower cleaning companies will be happy to do that for you.


Scale and biofilm removal is another key element in cooling tower cleaning. Different companies may deploy different cooling tower cleaning methods, but thorough cleaning aims to remove both scale and biofilm. Both of these issues will clog up cooling tower components and make your cooling system run less efficiently. Biofilm can also corrode the cooling tower and provides an ideal environment for bacteria to thrive. Leaving these issues to grow will lead to requiring either a much more intensive cleaning in the future or even replacing the tower entirely.


Cooling towers may also show other issues like algae growth that can seriously reduce their effectiveness. Cooling tower cleaning companies will often apply algae-killing chemical treatments to prevent algae from taking over your tower.


Finally, cooling tower cleaning companies will also inspect the tower thoroughly for any signs of corrosion or other damage. Depending on the extent or severity of the damage, this might require repairs, replacement of components, preventive maintenance or simply logging the issue as a potential future problem.


Cooling Tower Inspections and Estimates

Some cooling tower cleaning companies will offer a free inspection and estimate before working on your cooling tower. If this is an option, take it. A free inspection is a great opportunity to ask questions about the cooling tower cleaning process, discuss any specific maintenance needs that you have and find out how much the cleaning and maintenance will cost you.

While some cooling tower cleaning companies only provide cleaning services, others may offer other maintenance services like upgrades, rebuilds and preventive maintenance. If this is the case, they may recommend these services either instead of or in addition to cleaning if that is appropriate for your cooling tower.


Cooling Tower Cleaning Reports

Cooling tower cleaning companies will often leave you with a maintenance report on your cooling tower after cleaning it. Different companies will apply different cooling tower cleaning standards, but it is likely to include information on the work that they carried out as well as assessing the condition of key components. Depending on the company that you work with, the report may simply be text or they may supply supplemental photos.

Having maintenance reports to check makes it much easier to track developing maintenance issues, identify parts that may need to be replaced and choose appropriate preventive maintenance measures. If you decide to change cooling tower cleaning companies, having detailed reports on your cooling tower maintenance can also help to bring them up to speed.

Top 5 Cooling Tower Cleaning Methods

May 10, 2019

There are multiple ways to clean your cooling tower. Cleaning cooling towers requires a lot of special gear. Here are five cooling tower products that cooling tower cleaning professionals can’t live without.

Foaming Cooling Tower Cleaning Chemicals

Cooling tower cleaning services make use of a lot of different cooling tower cleaning chemicals, but foaming cleaner is one of the most useful. The inside of a cooling tower is full of little nooks and crannies that can be very difficult to get at with cooling tower cleaning tools, and disassembling the tower greatly extends how long maintenance takes. A foaming cleaner will expand into tight spaces like the cooling tower fill, getting great coverage of surfaces without much effort and making cooling tower cleaning procedures more effective.

Cooling Tower Cleaning with Pressure Washers

Scrubbing out a cooling tower with manual cooling tower cleaning methods like brushes and squeegees is time-consuming. When a cooling tower needs cleaning, many professionals turn to pressure washers. Just blasting away with a powerful pressure washer will damage delicate cooling tower fills, though. Lower-powered pressure washers with less than 1500 psi of pressure will effectively clear sludge and debris off the fill without doing any damage. Specialized hoses and nozzles give cleaning professionals the extra flexibility they need to tackle different types of tower and use different cooling tower cleaning methods.

Cooling Tower Cleaning with Biocides

The warm, wet conditions inside a cooling tower provide a great environment for biological contaminants, and many cooling tower cleaning methods and tools are designed to deal with this exact problem. Bacteria like Legionella can rapidly colonize a cooling tower and spread potentially fatal diseases as they are dispersed by the cooling system. Algae is also a major issue, with algae blooms threatening to clog up pipes and damage components. Microorganisms will also cause the buildup of biofilm in your cooling tower, which can corrode surfaces and also acts as a great heat insulator, making the tower run a lot less efficiently. Mold is also a fairly common problem inside cooling towers.

One common biocide is chlorine, which is often used as a preventive cooling tower cleaning method. Other more specialized biocidal cooling tower cleaning solutions are usually designed to target specific organisms such as bacteria or algae, and are added to tackle a specific problem instead of as a general preventive measure.

Cooling Tower Cleaning with Vacuums

Cooling towers are open to the air and can accumulate all kinds of contaminants over time. During cleaning, removed scale and biofilm, as well as excess cleaning chemicals and contaminated water, will end up sitting in the cooling tower basin. One cooling tower cleaning method that a lot of professionals use is to deploy a specialized vacuum to get all of the sludge and debris out. These wet/dry vacuums can remove all kinds of debris from chemical sludge to chunks of limescale, often without even having to drain the basin first. Attaching different accessories can equip the vacuum for whichever cooling tower cleaning method is needed.

Cooling Tower Cleaning with Commercial Bleach

Preventive cooling tower cleaning methods reduce biofilm buildup and other issues between scheduled tower maintenance sessions. One of the most common ways to kill off bacteria in a cooling system is to introduce chlorine into the cooling water. This can be done with chlorine gas, but commercial bleach provides a source of chlorine that is inexpensive and easier to store safely.

When using bleach, it is important to monitor your water chemistry regularly. Adding too much bleach will corrode your cooling system while adding too little won’t achieve the results that you want. Overly hard water will also reduce the effectiveness of bleach.

Choosing And Checking Cooling Towers For Sale

With so many different cooling towers for sale, choosing the right one can be difficult. However, there are a few key specifications that can often make the decision for you. Learn how to choose and inspect the right tower, without necessarily having to know in great detail how cooling towers work.


How Should You Choose Between Cooling Towers For Sale?

Decide how much cooling capacity you need and choose towers accordingly. To measure cooling tower capacity, look at the tower’s rating in nominal tons or US gallons per hour.


Decide how much space you can set aside for a cooling tower. This determines how large a tower you can have, and also helps to make some other decisions like choosing between crossflow and counterflow towers.


If you need cooling capacity of 1400 tons or greater, consider a modular cooling tower. This makes shipping easier and many modular designs can be scaled up as your business expands.


Decide whether you need an open or closed loop cooling system. Closed loop systems will keep outside contaminants out of your cooling water. If you are concerned about how much cooling towers cost, though, open loop systems are usually less expensive.


How Should You Inspect Cooling Towers For Sale?

If you find a cooling tower for sale used, you should inspect it thoroughly before committing. While new cooling towers should be free of issues when they come straight from the manufacturer, it can still be a good idea to check. The quicker you catch any cooling tower operation issues, the quicker you can deal with them.


One of the key problems that can crop up in cooling towers is corrosion, so be on the lookout for any signs of rust or metal damage. Joints and bolts are potential hotspots for corrosion, and checking any stairways or walkways should also be a priority.

Also, look out for any issues that might obstruct the flow of water. Make sure to check nozzles for signs of corrosion or clogging, taking them apart if necessary. Piping and basins should also be inspected for leaks or issues with the sealing.


Damage to fans can also prevent your new cooling tower from working efficiently. Make sure that all pulleys and belts are taut and free of wear and ensure that the fan shaft can spin freely. You should also inspect for any damage to the blades, as a blade that has lost structural integrity can cause a lot of damage if it breaks while spinning.


When looking at used cooling towers for sale, get the complete maintenance records for the tower. A tower that has been cleaned and inspected regularly has a much better chance of working well in the long run.


Before Using Your New Cooling Tower

Get your cooling tower professionally installed. These are large, complicated pieces of equipment, so it is a lot easier if they are installed correctly the first time.


If you found your cooling tower for sale used, have it cleaned before using it as it may have been sitting unused for some time. Generally, a tower should be cleaned if it has been out of use for five days or more. A specialist cooling tower cleaning company like Pinnacle Cooling Tower Service can help you with this.


Even if you found your cooling tower for sale brand new, doing some preventative maintenance before use can be a good idea. Corrosion-resistant coatings and biocides can help to stop maintenance problems before they start.

What is a modular cooling tower

What is a Modular Cooling Tower? Modular Cooling Towers Explained

February 10, 2019

Cooling tower manufacturers are increasingly turning out modular designs and many businesses have adopted modular cooling towers to meet their cooling needs. But what is a modular tower, and why might they be the right option for you?


What Is a Modular Cooling Tower?

Ordinary, non-modular cooling towers are assembled at the factory and then shipped and installed in a single piece. This is a convenient system for many businesses, particularly smaller ones, but it has a few downsides that modular designs get around.

The alternative to a factory-assembled cooling tower is a field erected cooling tower. 


These cooling towers are shipped in several pieces and then set up once those pieces reach where they need to go. This has obvious advantages for shipping in particular. For bigger cooling towers, shipping the tower all in one piece can be very difficult. On the other hand, it makes the tower more of an effort to set up.


Modular cooling towers go a step further. In many modular designs, each separate piece can function independently as a complete cooling tower. These pieces can be used in groups to provide extra cooling capacity. This makes it quite easy to scale the complete cooling tower to your business. If you have relatively low cooling needs, you can just use a single module, but you can also use a large number of them together if you need greater cooling capacity.

What Are The Advantages Of Modular Cooling Towers?

Shipping a few smaller components is often easier than shipping one large one, especially if the large tower won’t fit on a truck. If you require a large cooling tower, it may need special equipment to ship and may not be transportable on regular roads. This is why preassembled cooling towers tend not to come with capacities greater than about 1400 tons. Larger towers are just too impractical to transport in one piece. Modular towers may even be completely assembled at the factory, minimizing the amount of work to do on-site.


Scalability is a huge advantage for modular cooling towers. If each cell is a complete cooling tower by itself, it becomes very easy to choose the right capacity for your business. If you expand your business and need greater cooling capacity, you can just add extra cells.


Some businesses need more cooling capacity than they can realistically get from a single preassembled cooling tower. Power plants and large factories will almost certainly need more capacity than 1400 tons. If you will be choosing multiple cooling towers either way, it often makes sense to go modular.


Cleaning Modular Cooling Towers

Cooling tower cleaning and maintenance can take a bit longer for many smaller cooling towers than it can for one larger one if each module has to be accessed separately.

Many manufacturers design modular cooling towers specifically for ease of maintenance, so the extra time investment doesn’t have to be large.


The same cooling tower cleaning equipment and cooling tower cleaning methods that you would use for a non-modular tower can still be used. Cooling tower cleaning products are also the same for modular and non-modular towers.


The frequency of cleaning also doesn’t need to change. Like factory assembled cooling towers, modular towers should be cleaned at least twice a year.

4 Ways To Make Cooling Tower Cleaning and Maintenance More Effective

February 28, 2019

Cleaning out a cooling tower can be a big task, but it doesn’t have to be. Just a few simple methods can make cooling tower cleaning and maintenance much quicker and easier.


Regular Cooling Tower Cleaning And Maintenance

Different kinds of cooling tower contamination feed back into each other. Scale provides a great environment for bacterial biofilm to grow on. Biofilm corrodes your cooling tower, reducing its working life. That corrosion also provides new places for bacteria to hide. Biofilm also gets more durable the longer it is allowed to build up, making it harder to remove even with aggressive cooling tower cleaning and maintenance methods.


Putting off cooling tower cleaning and maintenance makes it exponentially harder to clean when you finally get around to it. OSHA recommends at least two thorough cleanings each year to prevent Legionella bacteria from growing in your ventilation system, but even more regular maintenance can help to keep your cooling system clean and clear.


If you want to know how to increase cooling tower efficiency, the answer to that is also regular cleaning. Scale, biofilm, algae and corrosion all reduce cooling tower efficiency, leading to higher power bills and potentially expensive damage to your ventilation system.


Cooling Tower Cleaning: Preventative Measures

Preventative measures aren’t a substitute for cleaning, but they can make cooling tower cleaning and maintenance much quicker and easier.


Applying an anti-corrosive coating to cooling tower components helps to prevent corrosion by creating a protective layer between the metal and the water. It won’t prevent corrosion indefinitely, but it can slow it down exponentially.


Adding anti-scalant chemicals to your cooling water helps to prevent scale building up inside your cooling tower and the rest of your cooling system. Sulfuric acid can also be used to reduce water alkalinity, which also helps to prevent scaling.


Adding the right chemicals to your cooling water can also help to kill off biofilm. The most common of these is chlorine, which is usually introduced to the water in the form of 10 percent commercial bleach.


Testing your water regularly is also a key part of using these cooling tower cleaning methods. While they are very useful for cooling tower cleaning and maintenance, adding too little won’t give you the effects you want. Adding too much of some of these cooling tower cleaning tools can also be a problem. For example, commercial bleach can corrode cooling tower surfaces.


The Best Times For Cooling Tower Cleaning and Maintenance

Cooling tower cleaning and maintenance is absolutely necessary, but it means shutting off parts of your cooling system while the cleaners are at work. The best times to clean are in the spring just before cooling season starts, and then again in the fall right after turning it off for the year. Exactly when this occurs will depend on your local climate.


Cooling towers should also be cleaned before switching them on if they have been sitting idle for a while. If the tower has been unused for 5 days or more, it is a good idea to give it a quick preventative cleaning before using it again.


The fourth way to maximize your cooling tower cleaning is to leave it to the experts.

Cooling tower cleaning and maintenance

4 Ways To Make Cooling Tower Cleaning and Maintenance More Effective

March 18, 2019

Cleaning out a cooling tower can be a big task, but it doesn’t have to be. Just a few simple methods can make cooling tower cleaning and maintenance much quicker and easier.


Regular Cooling Tower Cleaning And Maintenance

Different kinds of cooling tower contamination feed back into each other. Scale provides a great environment for bacterial biofilm to grow on. Biofilm corrodes your cooling tower, reducing its working life. That corrosion also provides new places for bacteria to hide. Biofilm also gets more durable the longer it is allowed to build up, making it harder to remove even with aggressive cooling tower cleaning and maintenance methods.


Putting off cooling tower cleaning and maintenance makes it exponentially harder to clean when you finally get around to it. OSHA recommends at least two thorough cleanings each year to prevent Legionella bacteria from growing in your ventilation system, but even more regular maintenance can help to keep your cooling system clean and clear.


If you want to know how to increase cooling tower efficiency, the answer to that is also regular cleaning. Scale, biofilm, algae and corrosion all reduce cooling tower efficiency, leading to higher power bills and potentially expensive damage to your ventilation system.


Cooling Tower Cleaning: Preventative Measures

Preventative measures aren’t a substitute for cleaning, but they can make cooling tower cleaning and maintenance much quicker and easier.


Applying an anti-corrosive coating to cooling tower components helps to prevent corrosion by creating a protective layer between the metal and the water. It won’t prevent corrosion indefinitely, but it can slow it down exponentially.
