Dry Coolers (Radiators) are widely used in the energy sector for the expulsion of waste heat from the system. For hassle free cooling of machines like motors and combustion turbines in a power plant, and for healthy operation of the system, the Dry Coolers to be used must be selected carefully. This paper discusses the basic points that should be taken into consideration in selecting a cost-friendly and durable Dry Cooler, capable of providing the required cooling capacity at high performance, by offering practical values to be used in selection. The scope of the paper includes information on the materials, design criteria and fans commonly used for Dry Coolers, as well as an introduction to LT-HT Radiators and Dry Coolers –which have an important place in the energy sector- with a focus on practical application.
