Warm process fluid (1) enters through a heat exchange coil (2) and gets water sprayed on by the spray system (3) at the top of the cooling tower. At the same time the axial fan (4) draws ambient air upwards (5) through the tower. During operation, heat is transferred to the water, and then to the atmosphere as a portion of the water that evaporates. The cooled process fluid then exits the unit (6). The sump (7) or basin collects the remaining water. The spray water pump (8) recirculates the water back up to the water spray system. The warm saturated air (9) leaves the tower through the drift eliminators (10), which remove water droplets from the air.
