Piping
Although side inlet piping is provided as standard, Class 600 towers are adaptable to end inlet piping. This is an economical method requiring only one riser for each series of hot water basins, regardless of the number of fan cells. Cast iron, steel, and reinforced plastic pipe are all available.
The open, gravity flow design allows the operator to vary water rates over a wide range while maintaining uniform water distribution to the
Valves
towers have proved their reliability in more than 40 years of service. The oversized valve body effectively dissipates velocity, providing uniform water distribution.
Splash Boxes
Each flow control valve discharges into a splash box located in the hot water basin. The lower box delivers water to the hot water basin both through slots in the bottom and by overflow. The cover box dissipates directional velocity and controls splash.
Nozzles
The “spiral target nozzle” metering orifices used in the hot water basins are specially designed to deliver the required water rate and are highly resistant to temperature and weathering damage. The use of “target nozzles” also provides uniform water distribution throughout the fill area with no need for a separate diffusion deck.
