39 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 is in an open space. However, when this is not possible, correct layout guidelines must be followed to provide satisfactory installation. INCORRECT: Wind effect with top of unit lower than top of wall 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). 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. CORRECT: Installation elevated so that top of unit is higher than top of 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. TABLE 1 SINGLE UNIT INSTALLATION TABLE 2 MULTIPLE UNIT INSTALLATION 38

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

40 RECOMMENDED UNIT LAYOUT 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. C. SPECIAL ENCLOSURE INSTALLATION 1) Solid Wall Enclosure 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 unit should be oriented so that the air flows uniformly to the air inlets on all louver sides of the unit. The air discharge of the unit must be level with or higher than surrounding walls. TABLE 3 2) Louvered Wall Enclosures EC-S Series Cooling 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.

The casing, louver and fan cylinder shall be made of Fiberglass Reinforced Polyester (FRP). 5.0 MECHANICAL EQUIPMENT 5.1 Fan(s) shall be propeller type, incorporating heavy duty blades of cast aluminium alloy. Blades should be individually adjustable. 5.2 V belts shall be of rubber and pulleys shall be cast aluminium alloy with the grooves of standard dimensions. FRP Belt cover must be provided to protect V belts from moist discharge air. 5.3 Motor(s) shall be TEFC, weather proof, squirrel cage, for 3 ph/50hz/415v power supply and installed outside air stream. 5.4 The complete mechanical equipment assembly for each cell shall be supported by a rigid, welded, hot dipped galvanised steel structural support. Vibration limit switches must be installed to shut off the motor if excessive vibration occurs. The switch is located on the motor end of the mechanical equipment support outside he fan cylinder, so as not to be exposed directly to the discharge air stream and for ease of maintenance and access to reset. 6.0 FILLS, LOUVERS AND DRIFT ELIMINATORS 6.1 Fill shall be film type, rigid, corrugated PVC sheets that are conducive to cooling water with UV protected and self extinguishing properties. Fill shall be cross-corrugated and the surface of the sheet shall have a suitable micro-structure to improve turbulence and water distribution. Fill sheets shall be bonded at all contact points. Fill shall be of alternate tip configuration to improve water drainage and minimize air pressure drop. 6.2 Drift Eliminators shall be assembled in easily removable modules. Drift Eliminator shall be 3 pass sinusoidal-shaped blade type. Guarantee drift losses must not exceed 0.005% of the design water flow rate. 7.0 HOT WATER DISTRIBUTION SYSTEM Each cell of the tower shall be equipped with hot water distribution system. Header and lateral pipes shall be PVC. Nozzles shall be non-clogging, capable of passing objects up to 25mm in diameter. The spray must be designed such that the nozzle outlet is the lowest point in the system. The water inlet connection shall be located outside the tower casing. No rotating mechanical sprinkler system is allowed. 8.0 COLD WATER BASIN The cold water basin shall be of FRP and supported on HDG Steel framework. The basin shall be designed with sufficient water capacity to avoid air entrainment in the outlet during operating conditions. FRP sump(s) shall be provided and equipped with suction strainer, make-up ball valve, overflow and drain. For multiple tower arrangement, equilising pipes between basins shall be provided to maintain the same level of water in each basin. 9.0 ACCESS AND SAFETY Service and maintenance platform must be constructed at the fan deck level to facilitate easy inspection & maintenance of the fan machinery.
