Best maintenance practices for top cooling tower performance

Industrial & Manufacturing Blog

Whether you are using your cooling tower to provide air conditioner cooling or for powering your production firm, one thing remains constant—it will definitely be one of the greatest energy consuming investments you'll have. This is because the cooling towers consume large amounts of water as they operate by using it to release heat from the building to the atmosphere. In order to have your cooling towers operating at optimum, you need to maximize energy efficiency. Here are some of the best practices you can implement.

Design for end use

One of the crucial things to look out for if you want an efficient cooling tower is its design. Ensure it is well designed for its end use. And even though its sizing is important, the materials used to construct the cooling tower should also be appropriate for the environment it will operate in. For instance if you are living at the coast, then make sure you use stainless steel instead of galvanized steel. Remember, the tower will be exposed to sea air, and the corrosive nature of the air will lead to unplanned downtime. Using stainless steel will prolong its life and offer corrosion resistance as well.

Install a sun shade

Inhibit the growth of algae on your cooling tower by installing a sunshade. Remember, most towers are plagued with algae at their tops when they are exposed to sunshine. And the growth of algae will inhibit the flow and distribution of water over the cooling surface. Eventually, the general efficiency of the cooling system will be reduced. That is why you need to cover the cooling tower decks and prevent sunshine from reaching them.

Choose the proper size

For your cooling tower to work effectively, then you must pick the right size. You do not want to buy a smaller tower as the machines will overwork and exceed the limits of the cooling system. The result is costly downtime. Likewise, an oversized cooling tower has it downsides. Remember, cooling towers operate on the principle of removing heat by spreading it across the PVC heat exchange media. This is what experts use to determine the tower's capacity. To have an easy time calculating the surface for the water-to-air interactions needed, call in a professional. Among other factors experts consider include humidity, temperature and any other necessary weather data. All in all, it is crucial to correctly size the tower in order to ensure top performance throughout its lifetime.

Finally, ensure you regularly do checks and repairs on your cooling tower because keeping it in its optimum operation efficiency is a long term journey and not a one time event.

Creating a Safe Environment: Industrial and Manufacturing Facilities

If you work in or run an industrial or manufacturing facility, safety is key. In this blog, we are going to talk a lot about safety. However, we are also going to veer into other aspects of these industries as well. There will be posts directed toward consumers, business owners, workers and many others. Before you start reading, let me introduce myself. My name is Steve. I used to volunteer at an animal refuge where I put together a lot of buildings and frequently visited sheet metal processing facilities, fence manufacturing companies and similar businesses. I was incredibly interested in what they did so I decided to create this blog. Thank you for reading.
