Factory-assembled towers

Recent trends have been towards an increase in factory-assembled over field-erected jobs because of the rising cost of field labor, which has far offset the higher transportation costs of shipping complete packages. In addition, manufacturers are better able to control the quality of fabrication. [Pg.74]

Gear boxes are used on just about all large field erected cooling towers and many factory assembled towers- all of the propeller ty e fan, draw-through type. Almost all are right angle gear drives with the input shaft horizontal and the output... [Pg.84]

Mechanical-draft cooling towers can be either field-constructed or factory-assembled systems. Installations that are constructed onsite are generally those employed at utility stations. Factory-assembled towers have applications in smaller industrial operations. [Pg.70]

Elements of a factory-assembled tower are basically the same as field-erected towers. The main difference is that in factory-assembled units, the design is modular in concept, with units shipped as modules and arranged on site. Figure 4.17 shows a typical installation. Manufacturers offer considerable flexibility to permit best use of available space for their equipment. [Pg.74]
