Warm process water (1) from the heat source enters the spray system (2) at the top of the cooling tower where it is distributed over the fill or heat transfer media (3). At the same time the axial fan (4), located at the top of the unit, draws the air from the sides of the unit (5) over the fill. Combined inlet shields (6) protect the tower from debris being drawn into the unit. While the warm process water contacts the cold air the latter heats up and part of the process water is evaporated which removes the heat from the remaining water. The sloping sump (7) or basin collects the cooled water after which it returns to the heat source of the process (8). The warm saturated air (9) first passes through the drift eliminators (10), which remove water droplets from the air, and then exits the tower at the top.
