- Page 1 Marley Class 600 Cooling Tower...
- Page 3 / Flexibility of Design / Class 600 cooling towers are a direct descendent ® of the Doubleflow crossflow tower that was designed and patented by Marley in 1938. In 1957, Marley’s development of hanging fill, wide indented louvers, and stable FRP velocity-recovery fan cylinders enabled the evolution of that Doubleflow tower into the classic Class 600 shape and function that has set the standard for splash-fill crossflow towers for the past half-century.

Marley fans are applied in accordance with data from model tests conducted in the wind tunnel at the SPX Cooling Technologies’ Research and Development Center. Model fan designs are tested in simulated cooling towers, and are fine-tuned to maximize efficiencies at actual conditions. - Page 5 Geareducer ® The Marley Geareducer has become the standard by which all other cooling tower fan speed reducers are judged. Numerous reduction ratios are available so that horsepower is applied at optimum fan speed. The specific Geareducer selection is based on fan speed and horsepower requirements up to 300 hp per fan.
- Page 6 / Fill / Class 600 splash fill bars are available in the following materials: • PVC in “Omega”, “Mega” or “Alpha” configurations. • Injection-molded polypropylene “Ladder” configurations. • Rough sawn, preservative-treated wood “G” configurations. Each cooling tower application is individually reviewed to assure selection of the proper fill type and fill spacing. Performance is computer optimized to assure maximum cooling from a given tower cell size for the design performance conditions.

/ Water Distribution System / 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. -
Page 8: Drift Eliminators
/ Drift Eliminators / Marley towers utilize Marley XCEL eliminators, a cellular, labyrinthine design which improves drift elimination by several orders of magnitude over that achievable by blade-type eliminators. Significantly lower pressure losses also reduce fan horsepower requirements. XCEL eliminators are thermoformed PVC bonded into easily handled, rigid packs which “nest”... - Page 9 The diagonals brace the structure and carry loads to heavy-duty, hot dip glavanized anchor castings. The anchor castings transmit wind and/or earthquake loads from the structure directly into the foundation. For standard wind load conditions, anchor bolts are required only at the perimeter. Structural ceramic rings or glass reinforced nylon shear plates are used in conventional connector ring joints where greater strength is required than bolted...
- Page 10 / Casing / The endwalls of Class 600 towers are cased from the fan deck level to below the top of the basin curb with 8 oz/sq ft corrugated FRP sheets. FRP is waterproof and corrosion proof, is immune to biological deterioration, and requires no maintenance.

Page 11: Maintenance Options
/ Maintenance Options / Endwall Derrick The endwall derrick is a permanently installed tripod device of galvanized structural steel. In service, removable structural aluminum tracks are positioned across the platform opening. Equipment to be handled is placed on a 4-wheel dolly—part of the equipment handling package—rolled onto the track and elevated slightly. -
