Common Faults & Solutions

A common issue you might run into is the cooling tower not doing its job effectively, resulting in the water coming out warmer than it should be. This usually happens because something is getting in the way of either the airflow or the water distribution. The biggest culprit is often the fill media, which is where the water and air mix to cool down. Over time, this can get gunked up with scale, dirt, or algae, making it harder for the heat to transfer. Likewise, the spray nozzles that distribute the water can become clogged or misaligned, causing some parts of the fill to run dry and reducing the tower’s overall efficiency. You might also find that the fan isn’t moving enough air, which could be due to a worn-out fan belt or an obstruction blocking the air inlets.

To fix this, you’ll need to conduct a thorough check. Start by inspecting and cleaning the fill media, making sure it’s free of scale and biological growth. Next, check all the spray nozzles for blockages and ensure they are properly aligned to provide a uniform water pattern. Finally, give the fan and its components a once-over to ensure it’s running at full capacity—check the fan motor, belts, and bearings, and make sure air inlets are free of obstructions. Regular water treatment is crucial to prevent these issues from recurring.

If you’re constantly topping up the cooling tower with water, you likely have a problem with excessive water loss. While some water loss from evaporation and drift is normal, a sudden increase points to a fault. The most straightforward cause is a leak in the cold water basin itself or its pipe connections. However, the problem could also be a simple mechanical issue like a malfunctioning float valve. This valve is what controls the water level, and if it’s stuck open or set too high, the tower will just keep calling for more water. Another common reason is damaged drift eliminators. These are designed to catch water droplets before they’re carried out of the tower by the airflow. If they’re cracked or not installed correctly, a lot more water than usual will be lost to the atmosphere.

First, visually inspect the basin for any leaks and patch them with a suitable sealant. Then, check the float valve to ensure it is operating freely and is set to the correct water level. Finally, inspect the drift eliminators for any cracks or improper fit. Replacing any damaged eliminators is essential for maintaining efficiency and conserving water.

Hearing strange noises or feeling unusual vibrations from your cooling tower is a major red flag, as it often signals a significant mechanical problem. This is almost always related to the tower’s moving parts, especially the fan. The fan blades might be out of balance, perhaps due to a build-up of dirt or damage. This imbalance can cause a lot of shaking and noise. Another cause could be a failing bearing in the fan shaft or motor. If these are worn out or haven’t been lubricated correctly, they’ll create a grinding or rumbling sound and a lot of vibration. For models that use a belt-and-pulley system, a loose or worn belt can cause squealing or a flapping sound.

If you hear these noises, the best thing to do is shut down the tower immediately and perform a mechanical inspection. Visually check the fan blades for any damage and clean off any debris to restore their balance. Check the fan shaft and motor bearings for any signs of wear and ensure they are properly lubricated. For belt-driven units, check the belt tension and alignment and replace any worn-out belts. If the problem persists, it’s best to consult a professional service technician to perform a vibration analysis and pinpoint the exact issue.

How Can I Keep This Tower Maintained?

Maintenance of the Evapco AT cooling tower can be supported through several accessories and systems:

Regularly clean the water distribution system to ensure proper flow.
Use SmartShield or Pulse-Pure water treatment systems for optimal water quality.
Perform inspections with maintenance accessories like platforms, ladders, and access doors.
Check the stainless steel basin and casing for leaks or damage.
Reduce noise with low sound fans or attenuation options if needed.
