Water is one of the wonderful things that god created. Cooling towers for water are used for the condensers, air coolers and oil coolers. The water is circulated through the heat exchangers by the main cooling water (C.W) Pumps and back to the cooling tower. Most of the water goes back to the river Nile, and Reverse Osmosis is used to recycle cooling tower water and thus reducing the total cost of the raw water.
