10 RECOMMENDED UNIT LAYOUT It is advisable to select and design the best layout or location to avoid air recirculation. Recirculation occurs when some of the hot moist discharge air leaving the cooling tower flows back into the fresh air inlet. The following guidelines will provide the best location or layout which will minimize recirculation, maximize fresh air flow and allow adequate maintenance accessibility. A. SINGLE UNIT INSTALLATIONS The best place for EC-S Series Cooling Tower is in an open space. However, when this is not possible, correct layout guidelines must be followed to provide satisfactory installation. Ensure that the top of the cooling tower is higher than any adjacent walls, buildings or other structures. Figure 1(a) and 1(b) are examples of incorrect installation. These conditions can be corrected by elevating the unit on structural steel/concrete plinths so that the top is higher that the wall as shown in Figure 1(c). INCORRECT : Wind effect with top of unit lower than top of wall CORRECT Installation elevated so that top of unit is higher than top of wall AIR AIR AIR AIR AIR AIR FIGURE: 1(a) FIGURE: 1(b) FIGURE: 1(c) When a cooling tower is located near a wall, consideration must be given to the clearance distance between the air inlets of the tower and the wall structure(s). See Figure 2, Recommended Dimensions and D2. Tower TABLE 1 SINGLE UNIT INSTALLATION Minimum Dimension (mm) (At Width Side) D2 (At Length Side) The minimum dimensions, and D2, as shown in Table 1 must be maintained to ensure that the unit is provided adequate air flow. In some installation, consideration must also be given to access to the unit for maintenance. Room must be provided for piping, removals of access panels, etc. Sometimes other pieces of equipment such as pumps, filters, piping etc are placed in front of the air inlets. These obstructions should not be located any closer than the minimum dimensions in Table TABLE 2 MULTIPLE UNIT INSTALLATION Tower Tower Width, W mm Minimum Dimension, mm D3 (End-to-End) D2 All models All sizes 1000 Tower Tower Minimum Length, L mm Dimension, mm D4 (Side-by-Side) FIGURE 2: INSTALLATION NEXT TO A WALL Below to 2020 Below The minimum dimensions are as listed in Table 2

11 B. MULTIPLE UNIT INSTALLATION TABLE 3 When more than one cooling tower is installed at the same location, recirculation becomes a bigger problem. Tower Minimum Dimension, mm D5 (At Width Side) With the installations of two cooling towers, they should be placed end to end with the narrows ends adjacent as shown in Figure 3. Another method is to locate the units side-by-side with the longer sides parallel to each other as shown in Figure 4. In either configuration, the distance between the units must provide adequate airflow as well as room for piping to the unit and access for maintenance. W FIGURE 3: MULTIPLE UNITS PLACED END TO END D3 Tower Consult Truwater s Design Engineer Minimum Dimension, mm D6 (At Length Side) Consult Truwater s Design Engineer 2) Louvered Wall Enclosures EC-S Series Cooling Tower can also be installed in enclosures with louvered or slotted walls and an open top (Figure 6) with this type of enclosure, the air flow patterns will be a mixture of the open type and well installation. The inlet air will be drawn from the top as well as through the louvers or slots. When considering a multiple-cell unit located in a louvered wall enclosure, the D7 and D8 dimensions, found in Table 4, must be used as absolute minimums.

SPECIAL ENCLOSURE INSTALLATION 1) Solid Wall Enclosures or Wells Figure 5 shown a cooling tower is installed in a well. When considering a multiple-cell unit located in a well, the D5 and D6 dimensions, found in Table 3, must be used as absolute minimums.

The air discharge of the unit must be level with or higher than surrounding walls. 10
