Water Distribution System

Warm water flows through external piping (not included with the tower) into a splash box chamber at the top of the Aquatower. A splash box prevents the incoming water from spilling out of the basin and helps provide uniform water distribution. Water then flows by gravity from the basin through nozzles to the fill.

Fill/Louvers/Drift Eliminators

Fill sheets include integral louvers and drift eliminators, designed to minimize resistance to airflow. This patented arrangement prevents water from escaping the fill sheets, assuring proper heat transfer throughout wide variations in airflow. Users find this fill operates ice-free even in extremely cold weather.

The thermoformed .4mm thick PVC fill sheets withstand hot water temperatures as high as 52°C. Fill sheets are immune to biological and corrosive decay and their flame spread rating is less than 25 per ASTM E-84. Galvanized structural tubes support and stabilize the fill. They also hold the bottom of the fill sheets above the cold water basin floor to simplify basin cleaning. Removable 25 x 25 mesh galvanized air inlet screens keep larger airborne trash out of the collection basin and fill area.

Hot water distribution basin covers are provided as standard equipment to keep the distribution basin free from airborne debris and to reduce the likelihood of biological growth.

All Aquatowers use Marley “Spiral Target” nozzles. These inert polypropylene nozzles are evenly spaced thoughout the distribution basin to assure uniform water distribution over all portions of the fill. Their large openings resist clogging. Nozzles are easy to remove and replace if you ever want to change the design water flow rate.

Cold Water Collection Basin

The Aquatower’s collection basin reduces operating weight, simplifies basin cleaning, and assures proper outflow. Water flows from the elevated area under the fill into the basin’s rear depressed section, where side suction piping connects. A bottom outlet is also available for gravity flow applications.

Standard equipment on each tower basin includes: a screened suction connection; a threaded overflow connection; a threaded and plugged drain connection; and a float-operated make-up valve. Models 492A through 496B also include a bottom outlet conforming to flat flange specification. A blank cover plate is provided to seal the outlet connection not used.
