There are many issues to be considered in design.


For example: water distribution system should be selected correctly according to tower inlet and outlet temperatures.

If the Pvc-u or PPrc (copolymer-added PP) materials are not selected at the correct temperature, breaks will occur due to softening the pipe or too much hardness.

Another issue in water distribution systems is the choice of pipe with appropriate pressure durability.

GRP (glass fiber reinforced polyester) stands out in the selection of polyester which is the building stone of the material. The use of orthophthalic polyester is more important in the selection of isophthalic polyester at higher temperatures.


If there is acidic basic density in the system, vinil polyester should be preferred.


The choices made by considering the design values are as important as the least complex design calculations.

If, for example, the "fill air speed" is too high, unnecessary water exits will be observed in the form of rain from the end of the water transport. This is definitely an unwanted condition and will cause leakage by increasing water consumption.

Or, if it is below normal, insufficient heat transfer will not be used in efficiency where the resulting tower can be used.

Another example can be given for the "rain water density" (rain density). Sometimes the tower flow is quite high and the design of the tower is very small when the temperature difference (delta t) is low.

In the case of overheating, the heat transfer between air and water is not efficient. In theory, it can not be realized due to the fact that the heat transfer unit which is envisaged to be easily made has a

lot of water on the filling surface. In this case, the designed tower size will be insufficient and will not need the system requirements.
