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 .
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.
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 .
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.
8 / A v ailable Options / Accessory Description and Remarks Accessory Description and Remarks Plywood Cold W ater Collection Basin Pressur e-treated Douglas fir plywood collection basin for towers located above grade. See page 11. Bottom-Outlet Sump Square-plan galvanized steel sump with bottom outlet.
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.
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 .
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.
