3 / Flexibility of Design / Class 600 cooling towers are a dir ect descendent of the Doubleflow ® crossflow tower that was designed and patented by Marley in 1938.
4 Fans Marley designed and manufactured fans ar e used on all Marley crossflow towers. The fan selection and fan speed for a given tower are based on tower cell size, system losses, and horsepower requir ements. Depending on fan size, blade material is FRP (fiber reinfor ced polyester), GRE (glass reinfor ced epoxy), or cast aluminum alloy .
5 Geareducer The Marley Geareducer ® has become the standar d by which all other cooling tower fan speed reducers are judged. Numer ous reduction ratios ar e available so that horsepower is applied at optimum fan speed. The specific Geareducer selection is based on fan speed and horsepower requir ements up to 300 hp per fan.
6 Class 600 splash fill bars are available in the following materials: • PVCin“Omega”,“Mega”or“Alpha” configurations. • Injection-moldedpolypropylene“Ladder” configurations. • Roughsawn,preservative-tr eatedwood “G” configurations.
7 Piping Although side inlet piping is provided as standar d, 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, regar dless of the number of fan cells. Cast iron, steel, and r einforced plastic pipe ar e all available.
8 / Dr ift Eliminat ors / Marley towers utilize Marley XCEL ® plus drift eliminators, a cellular , labyrinthine design which improves drift elimination by several orders of magnitude over that achievable by blade-type eliminators. Significantly lower pressur e losses also reduce fan horsepower requir ements.
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 structur e directly into the foundation. For standard wind load conditions, anchor bolts ar e requir ed only at the perimeter .
10 / Casing / The endwalls of Class 600 towers are cased fr om 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 pr oof, is immune to biological deterioration, and requir es no maintenance.
11 Endwall Derrick The endwall derrick is a permanently installed tripod device of galvanized structural steel. In service, removable structural aluminum tracks are positioned acr oss 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 .
