The advantages of counterflow cooling tower are:

1. It covers a small area, and the efficiency of the same volume is slightly higher than that of the cross-flow type.

2. It can produce greater water temperature difference.

The disadvantages of counter-flow cooling tower compared with cross-flow cooling tower are:

1. The internal structure is complex, the internal rotating water distributor is prone to failure, and it is inconvenient to maintain after failure.

2. It is easy to produce algae and silt, which can easily cause the blockage of the water distributor, which requires higher sterilization and algae removal.

3. The requirements for dosing are high. In addition to the metal pipeline, the rotating mechanism is also metal.

4. High head pressure requirements, high water pump configuration requirements.

5. The efficiency decays quickly, and the subsequent cooling capacity decays faster.
