TOWER structures are constructed from either Malaysian hardwood, zinc galvanised steel or FRP pultrusions. Most commonly used for process water requires very low temperature and high efficiency with respect to power consumption.

2 Applicable to process water with comprehensive water treatment programme. larger flow capacity and limited plot SeriesA similar type of COOLING TOWER to the PCT Series except the TOWER structure is constructed of reinforced concrete. This type of COOLING TOWER offer unlimited life span commonly applicable to larger COOLING TOWER size only. Although the initial construction cost is relatively higher, long life span and low maintenence cost over a longer term encourage this type of COOLING TOWER to be used in heavy industries and power plants where continuous operation over very long term is SeriesInduced draft cross flow COOLING towers with high efficiency PVC fill media and drift eliminators.

3 TOWER structures are fabricated from hot dip galvanized heavy gauge sections with FRP hot water basin, cold water basin and exterior casing. Most suitable for COOLING water requires very low temperature and high efficiency with respect to power consumption. Applicable to process water with comprehensive water treatment programme. larger flow capacity and limited plot SeriesInduced draft cross flow COOLING towers using timber splash bars as fill media supported on SS 304 grids. TOWER structure constructed from Malaysian hardwood with heavy duty design mechanical equipment for continuous operation & long life span. Most commonly used in applications where water is contaminated and high temperature service.

5 The COOLING towers were eitherthe prototype with a few smaller models combined together to make up forthe larger capacities; or single large unit of simple construction just merelyserving the purpose of COOLING water without considering other basicrequirement of the end users. As a result, many problems were left to theend user to solve on their own. And the objective of making COOLING towereconomical has never been achieved in actual operation if other factorssuch as initial overall civil and electrical construction cost, subsequentoperational cost, maintenance cost, spare parts replacement cost, downtime cost and TOWER life span were to put together as overall capital equipment, inefficient COOLING towers cannot be simplydiscarded away in most cases but to tolerate with whatsoever more users nowadays progressively gaining awareness on theimportance of the COOLING TOWER .

6 PANWATER has developed the modernPCF Series COOLING towers based on the user s needs couple with the vastexperience from more than a decade of making COOLING TOWER usingcomputerized thermal designing program. As a result, a completely newbreed of COOLING towers had been developed, tested and proven to meetevery individual s most demanding towers Induced Draft Counter Flow Multiple Cells Configuration Small To Large Capacities Compact Square Shape Small Installation Plot Area Light Weight Construction High Thermal Efficiency Low Power Consumption Drift Eliminator Inside Low Water Consumption Internal Distribution System Economical Piping Connections Robust Constructions Long Life Span3 Multiple Cells SystemEach model of the PCF Series COOLING TOWER has beenintentionally designed with multiple cells installation flexibilityto meet many COOLING TOWER system overall design nowadays.

7 So that the COOLING TOWER can be synchronized with theoperation of the multiple units of chillers, heat exchangers andwater pumps for ease of operation control and energyconservation. For this very important reason, it has beendesigned into multiple cells system to provide flexibility tohandle partial load for operation with varying capacities atdifferent stages, and for different changing ambient conditionwithin a day and different season within a year to achievehighest a result, PCF Series multiple cells design also simplifiedthe overall system piping works, civil foundation works andcomplicated control system. All these associated cost in theoverall COOLING water system that provide efficient operationare normally not reflected from the COOLING TOWER cost in many conventional COOLING towers , a singleunit of COOLING TOWER were being used to handle the overallthermal capacity but lacks the flexibility to take advantage oflower ambient wet bulb temperature when it is lower than thedesign to operate at partial load for energy conservation.

8 Andin most cases, maintenance of the larger and crucial componentsbecomes very difficult. Any minor failure usually leads tocomplete shut down of the entire COOLING system. Althoughmultiple cells COOLING towers have emerged in the marketrecently, but such COOLING towers were made for the purpose ofreducing the production cost with very few model. When largerunit is required, the TOWER size normally become unnecessarilyimpractical due to too many small cells. Such solution usuallyinvolved larger overall plot area, complicated piping system,high initial civil cost, complicated control system and still lacksthe flexibility in Duty ConstructionThe external COOLING TOWER casing, which provide theenclosure and supporting all the various components are madefrom the high strength, very durable and light weight FRPmaterials.

9 FRP materials offer flexibility to fabricateaerodynamic profile such as the fan housing and panels withhigh precision and yet offer very lightweight for ease ofhandling and ease of assembly. FRP construction is highlydesirable also due to its superior resistance to weathering andcorrosion since COOLING towers are to be located out door andare directly subject to severe weathering and in constant contactwith order to provide mechanical rigidity to the TOWER body,fabricated heavy gauge steel sections with hot-dip galvanizedto BS 729 is used In the PCF Series COOLING towers to providethe mechanical necessary for the framework to support themechanical equipment and the entire TOWER body for rigidityand durability as well as to ensure long lasting life Distribution SystemSince the performance of the COOLING TOWER is very muchdependent on the effectiveness of the hot water distributionsystem, complete internal piping system is provided within thecooling TOWER .

10 A single inlet connection flange is provided foreach cell of the COOLING TOWER is located at the sidewall casingpanel for direct connection with the overall COOLING water systempiping. Therefore, complicated and costly external pipingsystem and valves to achieve efficient water distribution andcontrol is not required. This feature is particularly necessary toavoid constant monitoring of water distribution to the coolingtower by external piping system in order to achieve the intendedperformance circulation water return to the COOLING TOWER via themain inlet header to each cell is redistributed through a seriesof smaller diameter lateral pipes and discharge onto the highefficiency PVC fill media below through the Polypropylenedownwards spray nozzles.
