Sweeper Jet

Electric H2O's Sweeper Jet is designed specifically for cooling tower basins. In order for cooling tower filters to do an effective job removing solid contaminants from the cooling tower basin, the solid particulates must be directed toward the filter inlet. Our Sweeper Jet nozzles achieve this through a uniquely designed elliptical discharge outlet that directs basin water toward the filter inlet in a flat fan pattern. This maximizes the performance of any cooling tower filtration system by actively sending particulates and sedimentation from stagnation zones in the tower sump to the filter. Dollar for dollar, the Sweeper Jet is among the most effective ways to improve water treatment performance.

Using the venturi principle, Sweeper Jets create a negative pressure region at the nozzle outlet, thereby forcing water into the elliptical discharge. This permits the use of a smaller pump to deliver the volume of water required for effective sweeping of solids to the filter inlet. The elliptical pattern sweeps a large path width, achieving a significant reduction in stagnant areas between nozzles. By directing solids toward the filter system suction intake, the Sweeper Jet system sharply reduces build-up of dirt, scale, airborne debris, sediment and other contaminants in cooling tower basins, sumps and machinery reservoirs.

Sweeper Jets are installed into a pipe that runs along the cooling tower basin bottom. Clamp-on swivel mounts are available to direct the sweeping path into hard-to-reach areas and to accommodate irregular shaped basins. Electric H2O provides sweeper jet systems tailored to each application. Basin size and shape, liquid depth, competing flow characteristics, solids loading and other site-specific criteria are examined for optimal flow and cleaning results. From there, Electric H2O determines the correct Sweeper Jet size, quantity and placement. A Sweeper Jet system combined with a properly sized and fully integrated filtration system will assure cleaner water, reduced plugging and fouling, and improved heat transfer efficiency. Suspended particulate removal also optimizes chemical usage, saving operational costs.
