The Effects of Scale on Your Facility’s Cooling Tower

One proven way to reduce spiking temperatures in industrial systems is by deploying cooling towers. Once embedded, a cooling tower becomes the crucial component in rejecting heat from process equipment into the towers bulk water. Likewise, the process equipment is dependent on a tower’s performance to then further reject that heat out of the system.

So, it’s important to control scaling in your cooling tower through a regular preventative maintenance program. If the tower fill has scaling, that deposit minimizes the amount of air the tower fan can pull through to efficiently cool the bulk water. Failure to protect your cooling tower and its associated equipment from scaling can have a corresponding result in downstream failures in your process. Wondering what those might be? Read on and learn about the risks of uncontrolled scale and what you can do about these threats.

HVAC Maintenance Implications of Nearby Fires

The West Coast is again facing epic wildfires filling the air with soot and ash settling onto roads, cars, and buildings, sometimes hundreds of miles away from the fires. For managers of commercial buildings, the flying ash increases the possibility of HVAC maintenance problems particularly in facilities with open cooling towers. Some building managers close to the fires have reported increased microbial growth in their open cooling towers as a result of the additional airborne particulates. The algae growth is clogging up the tower fill and wet ash is being drawn into the piping systems restricting the flow of tower water. If not immediately corrected, pipe fouling in open towers is an expensive and disruptive situation to correct.

How Boiler Cleaning Increases System Longevity

A boiler is one of the hardest working and longest lasting pieces of equipment in your facility. When properly maintained, boilers can keep things warm for fifteen years and, with older cast iron boilers, that lifespan can be well over thirty. In order to keep your boiler working efficiently for many decades, proper service and cleaning is a must.

Maintenance of the pumps and burners are critical, but special attention should be paid to the boiler tubes that, if neglected, can lead to expensive and catastrophic failures. The boiler tubes are where the water is heated (water side) and the fuel is burned (fire side). Maintenance staff have to clean both sides of the tubes to keep the boiler working properly.

A Primer on the Complexity of Different Scale Deposits

Complexity of HVAC Scale Deposits

Last week, Tim Fregeau, Goodway’s Director of Sales, Liquid Solutions Division, hosted a webinar titled  “Scale: Why You Have It, What It Does and How to Descale Safely and Effectively“. During the presentation, Tim discussed the importance of knowing what type of scale you have. Due to the complex nature of many scale deposits, it is important to identify them correctly, and in the end, this can save time and money.

Different types of Scale

Here’s a breakdown of the common types of scale you might find in your industrial equipment:

Where is Scale Likely Hiding in Your Facility’s HVAC Equipment?

If your facility’s machinery uses water as a heating or cooling medium, you likely know any water formed deposits will negatively impact energy efficiency and equipment life expectancy. When higher amounts of water and evaporation deposits settle, scale builds up. Keep in mind that a good portion of scale is hiding out and building up in difficult to reach places. Focusing in on all areas including these hidden spots will help keep operational costs down and equipment running smoothly.

So where are these scale hiding spots? Let’s break it down by equipment type.

A Facility Manager’s Guide to Understanding Scale and Why You Have It

When looking for efficiency killers in your plant, scale build-up in your hydronic equipment can be an obvious culprit. Facilities that use water for cooling and heating or power generation are most susceptible to the kind of heavy scaling that can reduce productivity. This is seen in pump pressure increases, approach temperature increases, and an increase in fuel consumption. When this happens, it’s time to take a look at possible scale accumulation.

So where did all that scale come from? While there are different types of scale, they can all be attributed to minerals within water falling out of suspension and depositing on surfaces. For many plants, these surfaces can be in the fill of cooling towers, inside pumps, or inside the tubing of heat exchangers.

Neglecting Proper Boiler Maintenance Can Mean Major Loss in Efficiencies

One problem you see with boilers in large institutions such as schools and universities is that cleaning and maintenance can be overlooked. This is often because boiler maintenance is not in the scope of work for HVAC maintenance staff and falls in the scope for the plumbing staff, who often don’t realize it’s part of their duties. It’s also often a misconception of staff that the highly intuitive controls that most new boilers have will prevent issues and send alerts when they occur, but controls are primarily responsible for boiler function boiler maintenance is still imperative for optimal operation. Otherwise, a boiler can sit for years, gathering scale and dirt that affects performance and can even cause premature malfunctions and breakdowns.

Latest Cooling Tower Legionella Outbreak Underscores Cleaning Solution Challenges and Importance of Ongoing Maintenance

Another Legionella outbreak linked to cooling towers this week re-emphasizes the urgent need for facility managers to develop an effective cooling tower maintenance program. As we mentioned in part one of this two-part blog series on cooling tower cleaning solutions, various studies strongly suggest 40% to 60% of cooling towers test positive for legionella.

This latest outbreak of the potentially deadly disease was caused by poorly maintained cooling towers in buildings around the central business district in Melbourne, Australia.

Five people between the ages of 51 and 71 were hospitalized. Authorities in Melbourne are analyzing 92 building systems in an attempt to lock down the source of the outbreak. While all five people have been discharged and are recovering, one had been on life support in intensive care.

Cooling towers with heavy limescale buildup on their cooling tower fill can be the perfect breeding grounds for legionella. Once the bacteria gains a foothold, it can infect the entire system. That means sick buildings and sick people, or worse. Short of sickness, dirty cooling towers can make your building smell bad, driving customers away. And there’s also the cost to your company’s image, which might never recover.

Limescale buildup in cooling tower fill isn’t just unsightly, unpleasant and dangerous. Dirty cooling towers increase costs, big time. Limescale buildup can dramatically decrease cooling tower efficiency. That’s potentially thousands of dollars added to your electricity bill for significantly reduced performance.

Still, cleaning dirty fill is a giant headache. It’s filthy, labor-intensive work, especially when done the old fashioned way, scraping limescale off by hand. Cleaning a heavily scaled up cooling tower usually requires multiple tools. Changing tools adds more time to an already labor-intensive process. No wonder so many businesses put off cleaning cooling towers.

However, there is an all-in-one solution available to help you keep your cooling towers clean that’s simple to operate. First, rinse down the cooling tower using an integrated power washing function. Then use an integrated chemical applicator to apply a powerful, yet safe, chemical descaler gel. The gel immediately reacts with limescale deposits to help dissolve and remove them, on contact. The final step is using an integrated turbo nozzle that includes a unique spray pattern to power clean the deposits. If limescale isn’t the issue with your cooling tower fill, use a foaming cooling tower fill cleaner and turbo nozzle combination to remove biological matter and dirt.

Check out this video to get a better sense of the simplicity and effectiveness.

An all-in-one solution means fewer man hours spent cleaning cooling towers and less downtime. That means you won’t have to put off cooling tower cleaning until the last minute, saving your company tens of thousands of dollars in reduced electricity costs annually — and no bad publicity for being the source of the latest outbreak of Legionnaires’ disease.

How Clean-in-Place Cooling Tower Solutions Reduce Hassle, Cost and Liability

Every year about 25,000 case of Legionnaires’ disease and 4,000 Legionnaires’-related deaths occur in the United States primarily due to poorly treated water systems. And your cooling tower’s hot, grimy water is a key contributor, according to a consortium of water treatment experts.

Why? When a cooling tower’s water reaches around 95 degrees in the hot summer months, legionella pneumophila, a ubiquitous aquatic organism, thrives.

Given such sobering facts, not to mention recent negative press, facility managers are certainly trying to be vigilant about cleaning their buildings’ cooling towers.

In a podcast on how to prevent legionella outbreaks, Ray Field, Goodway’s Liquid Solutions Director, says various studies strongly suggest 40% to 60% of cooling towers test positive for legionella.
