The water distribution system is installed between the drift eliminator and fill media in the tower. It distributes hot water by evenly spraying it on the fill media in the tower. The sprinkler device features a large-diameter ELLERT-type sprinkler head made of corrosion resistant polyvinyl chloride (PVC). The system offers a large flow rate, uniform sprinkling, no clogging, and enables the outer wall of the coil pipes to be fully coated with water with its spray. The distributor head is designed with a thread end for simple cleaning and maintenance.
