Tower Construction
Tower casing body is made out of F.R.P. (FiberglassReinforced Plastics) which is corrosion free, very durableand yet light. Furthermore the body is coated with aspecial epoxy consist of anti-ultraviolet agent making thetower body more resistant to UV sunlight. The tower mainstructure frame is using steel which has undergo hotdipped galvanization (HDG) process to prevent rust.
FillsThe film type cellular fill is made of air vacuum formingUltra Violet (UV) Light resistant PVC sheets whichhave corrugated surface. The surface has been speciallydesigned to spread the water droplet from hot waterbasin evenly.
Water distribution systemThe hot water basin is open gravity type flow made fromFRP material that is resistant to Ultra Violet (UV) Lightand corrosion. The water is distributed via speciallypositioned holes in the basin onto a scattering barsbelow. These scattering bars will sprinkle the watereffective and evenly on the fill section underneath.
The motor is of TEFC weather proof squirrel cage for 3phase 415 V / 50 Hz power supply.
The motor shall be located outside the discharge airstream below the belt cover to prolong the motor life andease of maintenance and access.
The fan bearing has a lubrication delivery system fromexternal point outside the fan stack to the fan bearing toallow grease top up to be carried even when the fan is inoperation.
Cold Water Basin
The cold water basin is constructed from F.R.P. (FiberglassReinforced Plastics) which is corrosion free and issupported by HDG steel frame underneath. The coldwater basin is also slopping basin to ensure the dirt andsediments trapped inside the basin is being divertedtowards the depressed sump in the centre of basin.
The depressed sump will prevent air lock from occurringduring the tower operation. The sump is also suppliedwith suction strainer, makeup water ball valve, overflowand drain connection.
moist discharge air. Optional aluminium alloy pulleys areavailable.
Mechanical drive systemFans are of axial type designed to deliver air performanceat low noise level. Fan blades material shall be FRP asstandard and aluminium alloy as optional. . All fan bladesare factory balanced before shipped out. The fan isoperating inside a fan stack enclosure to streamline theair entry while maintaining maximum fan efficiency.
The V belt drive system which connects the cast ironpulleys at the motor and fan is contained inside FRP beltcover. This is to ensure that the belts are protected from
The infill shall be installed in glued blocks and ease of
removable for cleaning. The second layer of infill blocks
shall be supported with galvanized pipes to prevent the
weight being imposed on the bottom layer.
Access DoorEach tower should be provided with as access door to
enter the internal compartment of cooling tower for
inspection and maintenance. The access door shall be of
FRP material and able to be locked.

RECOMMENDED COOLING TOWER ARRANGEMENT
11
Refer Table 1, for the distance recommended if cooling tower is located near to a wall.
Based on Figure 2, the wall near to the cooling tower is always recommended to be lower than cooling tower. This is to prevent discharge air from cooling tower to recirculate, as this will effect
the cooling tower’s performance.
It is always preferred, if the wall is a louvered wall, that there should be a 70% net free area and the louver height should not be higher than cooling tower.

SPECIAL OPTIONS
GEAR REDUCER
In addition to using V belt, right angle reduction gears are used for stringer application that requires no down time due to wear and tear. This type of option gives the building owner the convenience of planning the down time for planned maintenance. Design features and ratings are in accordance with the minimum requirements of AGMA (American Gear Manufacturers Association) and CTI (Cooling Technology Institute) standards.
HANDRAIL
The safety option is to ensure that working at elevated height of cooling tower is now complete with guard rail around the tower parameters. This option can be further enhanced with caged ladder which is an added feature as well.
HIGH EFFICIENCY MOTOR
Our high efficiency motor are rated to Eff2 or IE1 (standard) , EFf1 and IE2 (high effi ciency). We also offer latest IE3 (premium) standards as indicated by IEC 60034-30. The choice of efficiency is up the client’s preferences. For usage with variable speed inverters, we recommend special modification to the motor is required in order to allow the motor to operate at low frequency.
DISCHARGE HOOD
This option gives alternative diversion of hot air discharge from the fan stack to other direction deem more suitable. It is made from Fibreglass Reinforced Polyester (FRP) which is the same material as the fan stack. The most popular discharge angle is 45º.
CALCULATION OF MAKE UP WATER
14
2. Drift Loss ( D ) kg/h
The drift loss (D) depend on the type of cooling tower and drift eliminators used.Due to the air flow at a certain speed created by the fan, some water droplets arecarried away with the air, this is called carry-over loss.
There are many factors affecting the figure and this generally at a low level,approximately 0.005% of the normal circulating water quantity.
3. Blowdown Quantity (B) kg/h
The blow-down (B) can be carried out in any of the following methods
(1) The drain valve is kept slightly open during the run.(2) Maintain the operating water level higher to create slight overflow(3) The whole basin water is replenished with fresh water during shut down for cleaning
The required level of blowdown varies depending on the water quantity or the extent ofconcentrations, but is generally believed to be about 0.2% to 0.4 % for air conditioningapplications.
4. Replenishing Water Flow rate (R) kg/h
R = E + D +B
Therefore, the make-up water required is approximately= 0.98% + 0.005% + 0.4%= 1.385%
Hence, considering safety margin, a make up of 2% of the circulating water flow rateis sufficient.
Eg: Evaporation lossDrift lossBlow-down
:::
E = 0.98%D = 0.005%B = 0.4%
1. Evaporating Loss (E) kg/h
The evaporating quantity may be calculated by the equation below:
