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 EX-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 with 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.

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. The minimum dimensions are as listed in Table 2. 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-call 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 flow 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.

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.

EX-S SERIES CROSSFLOW COOLING TOWER SPECIFICATION 1.0 GENERAL The cooling tower shall be induced-draft vertical discharge type, crossflow, rectangular, film filled, FRP Cooling. It shall be designed with high efficiency drift eliminators to meet current environmental standards and guidelines for microbial control. 2.0 CAPACITY Cooling shall be capable of providing the thermal performance scheduled. 3.0 PERFORMANCE WARRANTY The rated capacity shall be certified by the Cooling Institute (CTI). The cooling tower manufacturer shall guarantee that the tower supplied will meet the specified performance conditions when the tower is installed according to plans. 4.0 CONSTRUCTION The cooling tower main frame structure shall be hot dip galvanized steel (HDG). The casing shall be made from Fibre Reinforced Plastic (FRP). 5.0 MECHANICAL EQUIPMENT 5.1 Fan(s) shall be propeller-type, incorporating heavy-duty blades of aluminum alloy. Blades shall be individually adjustable. 5.2 The V-belts shall be of rubber with fabric impregnated able to withstand the adverse ambient conditions of 50ºC and 100% R.H. The pulleys shall be cast iron with the grooves of standard dimensions. The entire V-belt & pulley set must be fully enclosed in a FRP molded case to protect the v-belts from in contact with the humid discharge air. 5.3 Motor(s) shall be TEFC, weatherproof sq. caged induction type suitable for 3ph/50Hz/415V power supply and with 1450rpm. 6.0 FILLS, LOUVERS AND DRIFT ELIMINATORS 6.1 Fill shall be high efficiency film-type, rigid, corrugated PVC sheets with integral louver and drift eliminator that are conducive to cooling tower and UV protected. 6.2 Fills shall be resistance to rot, decay and biological attack with maximum flame-spread rating of 5 according to ASTM E84. Fill module shall be solvent bonded supported from the bottom supporting beam. Hanging fill with structural tubing supported from the upper tower structure shall not be allowed. 6.3 Drift eliminators shall be efficient enough to effectively limit drift loss to 0.005% of the designed flow rate. 7.0 HOT WATER DISTRIBUTION SYSTEM An open basin above the fill bank shall receive hot water piped to each cell of the tower. Water shall enter the basin through a removable splash box. Removable and replaceable polypropylene nozzles installed in the floor of the basin shall provide full coverage of the fill by gravity flow. 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. The basin shall be equipped with suction strainer, make-up ball valve, overflow and drain. For multiple tower arrangement, equalizing pipes between basins shall be provided to maintain the same level of water in each basin. 9.0 ACCESS AND SAFETY Ladder shall be provided for inspection & maintenance purposes. HDG steel fan guard shall be provided over each fan cylinder. 18
