Because of the heat exchanger. Use the air as a cooling rather than cold water, so it is popular to quickly increase because of the current shortage of cooling water. The structure of 3-element is a bundle of tubes, which consists of a heat transfer tube with fins (Fin) steel structures for a bundle of hoses and bellows blow air with motor for a bundle of tubes. This type of heat exchanger with a blow dryer and air through mud tubes (Induced Draft) special features of this type of heat exchanger is not to rely on a cooling water (as a result, he doesn't have to seek water sources or fix problems with water quality) and the air used for cooling is limited and does not rust or dirt problem. Another example is the case of water maintenance. There are disadvantages: requires a lot of space in the installation, construction and investment values, must select a location to install the appropriate.
