Cooling towers are designed according to meteorological conditions which belong to the hottest summer days.

Essential main information for designing cooling tower is stated below:

• Amount of cooling water (m³/h) or capacity (kcal/h, kw)
• Temperature of hot water(°C)
• Temperature of cold water (°C)
• Wet bulb temperature value(°C)

Helpful information:

• Facility, using cooling water
• Quality of circulation water (pollution amount)
• Dry temperature degree of region(°C)
• Height above the sea level (m)

Important points in cooling tower requests;

• Tower demand should not be done by just stating the capacity.
• Water flow, which will circulate  in tower, hot  and cold  water temperatures should be noted.
• The most important point is the approach value of cooled water temperature to wet bulb temperature. By changing the approach of  water flow, hot water/cold water  temperature difference and cooled water temperature to  wet bulb temperature; it is possible to get many different capacities from the same tower.
