According to the flow direction of cooling tower and air to divide the cooling tower into two types─cross flow and counter flow. This article will lead you to know the difference of these two type cooling towers.

Counter flow cooling tower

Principle

In counter flow cooling tower, cooling air and water flow are in opposite direction, for this reason, it can reach maximum area of dissipation. It commonly used in round cooling tower, and also used in square cooling tower in some case.


Characteristic

  1. High efficiency of heat exchange.
  2. Inside structure complicated, difficult to maintenance.
  3. Easy to produced limescale and moss.
  4. Fills of round cooling tower can’t be maintenance regularly.
  5. It’s easier to occurs splash drift losses problem.
  6. Cross flow cooling tower

Cross flow cooling tower

Principle

In cross flow cooling tower, water is falling from above, the air and water are flow in vertical way. Because heat dissipation material is closed to the collection basin, the advantage is reducing water falling noise. Cross flow type usually used in square cooling tower, but the structure is fixed with large amount of iron piece, so it cost more higher than round cooling tower.


Characteristic

  1. Simple design.
  2. Easy maintenance.
  3. Low noise of water pressure.
  4. Smaller floor space, more economic benefits for long term use.

 


 

About JH HCT Mix Flow Cooling Tower

Our Jin-Hui Closed Circuit Cooling Tower is in mix flow type (Principle of closed circuit cooling tower), it combined with covering technology of heat exchanger tube, and the high efficiency cooling capacity, completely solve the splash drift losses problem, and kept the advantage of non-noise (HCT series closed circuit cooling tower). It also has the advantages of cross flow and counter flow.

Principle

In mix flow closed circuit cooling tower, the fresh air and flow direction of the spray water are in the same direction. The most important feature of this design is that can inhibit generate of limescale on the outer wall of the coil and increase the heat exchange efficiency. In addition, it has a large space for maintenance, and more convenient to maintain and repair.


Characteristic

  1. Overcome limescale problem.
  2. efficiency cooling capacity
  3. #304 stainless steel shell and coil (zinc aluminum-plate available).
  4. Air/water flow in the same way, and cross type design.
  5. Low splash drift losses.
  6. Large maintenance space.
  7. non-noise
