Compact Cooling Tower Technology Saves Energy
Induced draft, counterflow cooling tower is offered in single-unit capacities from 250 to 2,000 cooling tons. Series TM has a modular cooling tower design that allows isolation of cells for operational flexibility. Standard features include a seamless, double-wall, engineered plastic (HDPE) shell; corrosion proof construction; direct-drive fan system; totally enclosed motors rated for use with variable-frequency drives (VFDs); PVC water distribution system with non-clog large orifice removable nozzles; and high efficiency PVC fill. The structural shell is capable of withstanding water temperatures up to 160°F (71°C) on a continual basis. Between equidistant vertical ribs along the walls of each cell are precontoured sections that, when coupled with the structural foam between the double walls, add rigidity and overall structural strength. Each cell’s sump is molded to a slope aggressively toward the center and a 3 percent slope toward a depressed sump box near the outlet. This limits settlement of any dirt, debris or biological films and allows for complete drainage of the sump during planned shutdowns.
