2 Y ou’ll enjoy single source r esponsibility and reliability because we design and manufacture virtually all major cooling tower components. All Marley components are designed and selected to be part of an integrated system. For example, the spray pattern from nozzles and the pr essure dr op through drift eliminators both affect a fill’ s hea[...]

4 / Constr uction and Components / Fill/Louvers/Drift Eliminators Marley high-performance film fill is the heart of every Sigma tower . A repeating chevr on pattern provides the wetted surface and air turbulence necessary for proper heat transfer , while minimizing resistance to airflow so you’ll save on fan power . Molded protrusions on each [...]

5 fans, used on larger models, include hollow GRE (glass- reinfor ced epoxy) blades and epoxy-coated cast iron hubs. Blades on both fan types are adjustable in pitch, so you can take full advantage of rated horsepower or adjust the pitch to compensate for unusual job site restrictions. The true airfoil blades, designed specifically for cooling tow[...]

6 W ater Distribution System The gravity-flow water distribution system designed into the Sigma tower essentially reduces pump head to its most basic component – static lift – saving you money on pump power . Y ou won’t have to for ce water through internal piping and pressur e spray nozzles, as you would in a counterflow tower . W arm wate[...]

7 The 4" x" 4 tower diagonals carry loads to heavy- duty hot-dip galvanized steel anchor plates or hot-dip galvanized anchor weldments. The system of longitudinal and transverse diagonal bracing provides stability in a true tension-compression design. the mechanical equipment.

9 Cell Partition Options Every Sigma tower includes plenum chamber partitions and hot water distribution basin partitions between adjacent cells. Plenum partitions ensure consistent thermal performance as you shut off one fan at a time. They keep air from entering an operating cell thr ough an adjacent idle fan, maintaining efficient thermal perfo[...]

10 Fire Pr otection Options The PVC fill, louvers and drift eliminators used on Sigma towers are fir e-retar dant, having flame spread ratings less than 25 per ASTM E-84. Standard fan decking material is pressur e-treated fir plywood which ignites poorly and burns slowly . For these reasons, governing agencies (such as Factory Mutual) may not r[...]

11 Cold W ater Collection Basins If you plan to locate your tower above grade, a treated Douglas fir Marley cold water collection basin is available, complete with the necessary operating accessories. The basin floor is exterior grade, pressur e-treated fir plywood, supported on joists. Basin sides are plywood, machined to fit the basin floor [...]
