Counter Flow Cooling Tower

In a counter flow cooling tower design, the air flow is directly opposite to the water flow. Air flow first enters an open area beneath the fill media, and is then drawn up vertically. The water is sprayed through pressurized nozzles near the top of the tower, and then flows downward through the fill, opposite to the air flow.

Advantages of the counter flow cooling tower design:

  • Spray water distribution makes the tower more freeze-resistant.
  • Breakup of water in spray makes heat transfer more efficient.

Disadvantages of the counter flow cooling tower design:

  • Typically higher initial and long-term cost, primarily due to pump requirements.
  • Difficult to use variable water flow, as spray characteristics may be negatively affected.

counter flow cooling tower can be used in natural draft and in mechanical draft cooling towers.
