/ Marley Class 160 Cooling Tower /
/ The Marley Difference / You’ll enjoy single source responsibility and reliability How many other cooling tower companies can offer you because we design and manufacture virtually all major cooling this assurance? They may use Brand “A” nozzles with Brand tower components. “B” fill and Brand “C” drift eliminators. When they all come All Marley components are designed and selected to be together, the whole may be less than the sum of the parts. part of an integrated system.
/ Construction and Components / ■ Fill/Louvers/Drift Eliminators Marley high-performance film fill is the heart of every Class 160 tower. A repeating chevron 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 fill sheet assure uniform spacing. Fill sheets are vacuum formed 15 mil (.015″) thick PVC (polyvinyl chloride) capable of service at hot water temperatures up to 120°F.
■ Water Distribution System Class 160 towers offer the benefits of adjustable pitch propeller type fans. All fans used on Class 160 towers include The gravity-flow water distribution system designed into the hollow GRE (glass-reinforced epoxy) blades and epoxy-coated Class 160 tower essentially reduces pump head to its most cast iron or galvanized steel hubs.
The primary structural elements of all Class 160 towers Hinged doors through the endwall casing permit access to are the nominal 4″ x 4″ columns spaced on 4′-0″ longitudinal the interior of the tower at the basin level. Single-cell towers centers. A system of nominal 4″ x 4″ tower diagonals carries have one door. Multicell towers have doors in both endwalls, loads in both tension and compression to heavy-duty hot dip plus accessways through any and all partition walls.
/ Operating and Environmental Considerations / ■ System Cleanliness Cooling towers are usually selected to produce a specific cold water temperature at the higher summertime wet-bulb Cooling towers are very effective air washers. Atmospheric temperatures. During the remainder of the year, the cooling dust able to pass through the relatively small louver tower is capable of producing much colder water. Unless openings will enter the circulating water system.

/ Available Options / ■ Cell Partition Options the plenum chamber between fill banks, just inside the endwall access door to facilitate adjustment and maintenance. Every Class 160 tower includes plenum partitions and hot water distribution basin partitions between adjacent cells. Plenum partitions keep air from entering an operating cell ■ Fire Safety Options through an adjacent idle fan—assuring consistent thermal On specific jobs you may want to weigh the cost of various performance.
