Two circulation methods for cooling towers.

Closed cooling tower; also known as a sealed cooling tower or simply "closed tower." It features two distinct circulation loops: an internal loop and an external loop. At its core are heat exchangers made of materials such as copper tubes or stainless steel tubes.

What are the maintenance components of a cooling tower?

The service life of a cooling tower and how to maintain it are very important. Some customers can use it for 8 years, while others can only use it for 5 years. So today, let's talk about it.

How should scale buildup in closed cooling towers be removed?

It's quite common for cooling towers to develop scale buildup—similar to how limescale forms when boiling water in a kettle at home. Tap water is typically hard water, containing a higher concentration of dissolved minerals and impurities. When exposed to high temperatures, these substances rapidly break down, and the resulting ions combine to form calcium carbonate, which settles at the bottom. Over time, this accumulation leads to the formation of scale. In closed-loop cooling towers, cooling coils circulate the coolant, while a large volume of recirculating spray water continuously flows over the outer surface. Next, we'll use the closed-loop cooling tower as an example to explain how scale develops—and how it affects the performance of the cooling tower.

Why does the closed cooling tower keep losing water? What’s going on?

If a closed cooling tower continuously requires water replenishment, you should check whether there are any leaks in the cooling tower or its piping, since in most cases, only leaks can lead to insufficient volume in the circulation system, resulting in the need for frequent water top-ups!

How much can a cooling tower typically reduce the temperature by?

Normally, the temperature of a cooling tower cannot drop indefinitely—on paper, the lowest it can go is wet-bulb temperature plus 3 degrees.

What should you do if the product malfunctions during use?

1. For induced-draft units, inspect and confirm that the designed external static pressure matches the actual external static pressure. 2. Check that the water level in the drip pan meets the recommended requirements. Note: Air density directly affects the ammeter reading. Lower air density causes the fan to rotate faster, resulting in a higher current value.
