Draft forzado de la Ronda Marley

Reduced power consumption, favorable space requirements, minimized recirculation effects, optimum operational behavior for salt water application and the aesthetic look are only some advantages of round cooling towers with forced draft fans.

Principle of Circular Cooling Towers with Forced Draft Fans
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. Also maintenance activities can be accomplished in shut-off sections while the rest of the cooling tower is still in operation.

Reducción de Costos Operativos
Como el efecto de tiro natural favorece a los ventiladores, se reduce el consumo de energía. Especialmente mediante el uso de motores de dos velocidades se consiguen costes operativos considerablemente más bajos.

Eliminación de los efectos de recirculación
The plume is conducted by the higher shell, therefore the recirculation effect is eliminated. In contrary to the cell-type cooling towers where the risk of the plume falling on the ground and being drawn into the cooling tower must be considered.

Aplicación de agua salada
The higher rise of the plume results in a wider dispersion. That means for seawater application the salt particles are also better distributed in the air and the resulting salt concentration on the ground is considerably reduced.

Requisitos de espacio
The recirculation effect needs not to be taken into account for circular cooling towers therefore the space requirements are reduced. Also the circular shape is more favorable in comparison to cooling tower rows located in defined distances.
