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 TX-C 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 WIND DISCHARGE AIR DISCHARGE AIR DIRECTION DISCHARGE AIR WIND DIRECTION 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 D1 and D2. The minimum dimensions, D1 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. FIGURE 2 : Installation next to a wall. 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 1.

B. MULTIPLE UNIT INSTALLATIONS When more than one cooling tower is installed at the same location, recirculation becomes a bigger problem. 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.

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 enclosures, the D7 and D8 dimensions, found in Table 4, must be used as absolute minimums.
