Counter Current Cooling Tower has higher efficiency of the same volume, and offers larger water temperature difference. But it also comes with several disadvantages:
1.The unequal height between the air inlet and the water eliminator makes up the big Counter Current Cooling Tower and its high power consumption.
2.Meanwhile, the tower adopts nozzles to distribute water, which needs high pressure requirements and are easy to be blocked.
3.The entire tower body of the countercurrent tower is a closed structure, and it must be shut down when the equipment is overhauled or routinely maintained.
4.In addition, the rapid loss of water in the lower tank is very large, and it is easy to form water mist around the cooling tower, which is easy to cause the reproduction of legionary bacteria.
