Closed circuit cooling tower is used to combine a heat exchanger and cooling tower into a single compact unit. The process fluid to be cooled is kept clean in a contaminant-free closed loop in contrast to open circuit cooling towers. The lower fouling of the closed loop reduces system energy consumption. The cooling fluid pressure drops are reduced by closed loop and the closed circuit tower are installed below the equipment to be cooled. It has its own flow of water that is sprayed onto the condenser water circuit pipes to cool them down indirectly. Its applications include water source heat pump loops, air compress, water-cooled chillers and distributed cooling loops.

Cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of water stream to a lower temperature. It is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. A direct or open-circuit cooling tower is an enclosed structure with internal means to distribute the warm water fed to it over labyrinth-like packing. An indirect or closed circuit cooling tower involves no direct contact of the air and the fluid, usually water or a glycol mixture, being cooled. This tower lowers water temperatures like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in need of cooling.

Cooling tower is an evaporative cooler. It is used for cooling water or other working medium to near the ambient wet-bulb air temperature. It uses evaporation of water to reject heat from processes such as cooling the circulating water used in oil refineries, chemical plants, power plants and building cooling. The towers vary in size from small roof-top units to very large hyperboloid structures can be up to 200 metres tall and 100 metres in diameter, or rectangular structures that can be over 40 metres tall and 80 metres long. Smaller towers are normally factory-built, while larger ones are constructed on site.

A fill is an artificial ridge or dam of earth or gravel. It is constructing to support a prepared right-of-way such as a railroad or highway across a valley or depression.

Forced draft cooling towers are ideal to process larger cooling water flows. The features of cooling towers include reduced power consumption, favorable space requirements, minimized recirculation effects, and optimum operational behavior for salt water application. The hyperbolic shell achieves a natural draft effect which supports the fans arranged around the circumference of the cooling tower shell. Therefore the power consumption of the fans is reduced. The cooling tower is separated in different sections, which can be isolated, to ensure operation with lower water quantities.
