Your Cooling Tower Fan is Important, Treat it Right

With summer fast approaching, it is essential that you make sure your cooling tower is ready to handle the heat. While there are a wide variety of maintenance checks that will need to be completed to make sure that your tower is running as efficiently as possible, checking the fan in your cooling tower is one of the most important components to check. The fan inside of your cooling tower does a lot of work. Without this fan, your cooling tower is unable to function so it is in your best interest to make sure that it is in good shape. Here at Industrial Cooling Solutions Inc., we want all of our readers to be as informed as possible when it comes to topics relating to cooling towers and, in today’s post, we are going to cover a few essential maintenance tips that need to be performed to ensure that the fan blade in your cooling tower is working as efficiently as possible. Continue reading below to learn more.

Fans Need Maintenance as Much as the Cooling Tower

When it comes to cooling tower maintenance, there are a wide range of issues that need to be checked in order to be sure that the tower is performing as optimally as possible. From spray nozzles to fill material, a cooling tower is composed of many parts that need to work in conjunction with each other to make sure the tower is doing its job properly. Below, we have listed a few maintenance tips in relation to the tower’s fan blade system.

  • Check Blades: One of the first things to check when performing routine maintenance on a tower’s fan system is to check the fan itself. Cooling tower fans rotate at thousands of RPM and during that fast rotation even the smallest bits of debris can cause damage if they come in contact with the blades of the fan. Check the blades for any dings or cracks that may have formed and also use this time to clean the blades of any dirt that may have accumulated on them. It is important to keep the blades of the fan in good repair because even the smallest ding can develop into a crack. If one of the blades cracks while the fan is spinning, the results could not only result in damage to the cooling tower but could be potentially harmful to workers in the areas surrounding the tower.
  • Check Alignment and Balance: After you have checked the blades of the fan to make sure that they are in good repair, it is important to make sure that the fan is properly aligned and balanced. As we mentioned briefly in the previous bullet, industrial cooling tower fans rotate thousands of times every minute. As a result of this near constant rotation, the fan can sometimes become unbalanced. Like an unbalanced ceiling fan, the cooling tower fan will start to wobble as a result of its unbalanced state and create vibrations. Anyone who has at least a basic understanding of cooling tower fans knows that vibrations are never a good thing and should be avoided at all cost.
  • Check for Wear: As with any cooling tower component, it is essential to check for wear on any and all components relating to the fan. This includes the drive shaft, motor, and couplings that keep the fan physically attached to the rotator plate. Check these areas for rust or any other signs of degradation. While rust shouldn’t be an issue if the fan assembly has been properly maintained if you come across any make sure to address the situation. Rust can be handled if it is caught early, however, if it is left to grow it can cause major damage to the fan assembly and potentially cause the fan to break down.

How To Reduce Cooling Tower Fan Vibration

Cooling Tower Parts

The Less Vibration the Better

Hello, and welcome back to our blog. Here at Industrial Cooling Solutions Inc., we specialize in the construction and upkeep of industrial cooling towers and, as a result, we come across a lot of issues that crop up in the cooling tower industry. One of the most common issues that we run into has to deal with vibration. Anyone who deals with industrial machinery knows that vibration, unless it is specifically asked for, is hardly ever a good thing for machines to experience and can cause a lot of issues if not properly addressed. In relation to industrial cooling towers, vibration issues most commonly occur within the tower’s fan system. In today’s post, we are going to go over a few ways that you can make sure your fan system experiences as little vibration as possible. Continue reading below to learn more.

Contact us today and let us help you make sure that your cooling tower is running as efficiently as possible.

    Is Your Cooling Tower Fan Running Properly?

    Traditionally, rotating equipment is mounted at grade and uses the mass of a foundation and grout to reduce vibration and provide both support and stiffness to the rotation apparatus. Unfortunately, cooling tower fans are elevated several feet above a basin a basin of water and are most commonly held in place with support beams made of wood or fiberglass. This means that cooling tower fans do not get the benefit of a solid base to help reduce vibrations and must instead be tightly calibrated to reduce vibrations as much as possible. Below, we have listed a few steps that can be taken to help make sure that a cooling tower fan vibrates as little as possible.

    • Tighten Everything: When it comes to the structures responsible for holding a cooling tower fan in place, it is important to make sure that everything is held together as tightly as possible. Making sure the structure is as stable as possible be reduces the amount of movement that the fan can experience. Before beginning any other type of calibration work, make sure that the bolts holding the fan are as tight as possible as well as the bolts that hold the mounting structure to the tower. Additionally, it is important to check the bolts that hold the fan to the rotator. If these bolts have become compromised, the fan is more likely to become damaged.
    • Inspect the Fan: Once you have made sure that the structure holding the fan is as secure as possible, take a moment to assess the fan. Each blade of the fan should be securely fastened and angled in the same way. If you notice that any of the blades have become damaged, assess the situation to determine whether the blade can be repaired or if it is time to replace the blade altogether. If a single blade on the fan is warped or damaged, it can cause the entire fan to wobble as it rotates. While these wobbles might be tiny in the scheme of things, over time they can cause serious damage to the machinery designed to rotate the fan.
    • Inspect Gearbox and Driveshaft: While inspecting the fan blades is an important part of ensuring that the cooling tower fan experiences as few vibrations as possible, neglecting to check the mechanisms that actually rotate the fan can lead to issues as well. Without a properly functioning gearbox, the fan inside of a cooling tower will not properly rotate, causing myriad issues in terms of functionality and efficiency. When inspecting the gearbox and driveshaft, make sure to note any signs of wear that may have cropped up since the last inspection. While these components are designed to operate under heavy use for long periods of time, they are still machines and will become compromised if they are not properly taken care of.

    If after performing a maintenance check on your cooling tower fan system you find that there are some issues that need to be addressed, contact the experts at Industrial Cooling Solutions Inc. today. We offer a wide range of cooling tower maintenance services and we also provide a variety of cooling tower replacement parts.

    Is an FRP Cooling Tower the Right Choice for Your Project?

    Hello, dear reader, and welcome to part two of our blog series highlighting the advantages that FRP materials have over concrete in industrial cooling tower design. While we aren’t suggesting that certain applications won’t call for a concrete tower design, overall we are confident that FRP materials are a better choice in the majority of cases. In our last post, we listed a couple of advantages FRP has during the construction and design phase and, in today’s post, we are going to highlight some of the maintenance benefits associated with FRP cooling towers. We hope that by the end of this blog you feel more confident in your decision between these two materials.

    Maintenance is a Necessary Part of Industrial Cooling Towers

    All machines, no matter how well they are designed and manufactured, require maintenance. Industrial cooling towers are no exception to this rule and, often, maintenance costs over the life of the tower can become quite an expense. Below, we have listed a few ways that FRP cooling towers are easier to maintain than concrete cooling towers.

    • Cleaning: If you have spent time around an industrial cooling tower, you are well aware that they require routine, thorough cleaning. Scale buildup and biological growth can quickly inhibit the efficacy of a cooling tower and must be handled accordingly. FRP cooling towers allow for scale build-up and algae to be washed or brushed away with ease. Concrete cooling towers, on the other hand, are porous and tend to hold onto undesirable particles and growth that must be thoroughly scrubbed away. Not only do concrete cooling towers require more frequent cleanings, the amount of labor required to complete those cleanings is much more when compared to an FRP tower.Further, the closer spacing of the structure in the FRP cooling tower allows for easier cleaning without
