2.2 BODY SECTION
The _
All -Fiberglass
Cooling Towers
The closed circuit fluid cooler has one 01 seamless pieces body section, water -light and leak -proof, constructed of
corrosion -resistant material with Ultraviolet (UV) inhibitor, high-grade Isophthalic Polyester Resin. The Fiberglass
Reinforced Polyester (FRP) wall have a thickness no less than 114 inch; also to ensure the structural strength, the framing

inhibitor is only be used in the manufacturing process.
2.3 FAN DUCT
The closed circuit fluid cooler has two 02 fan duct constructed of corrosion -resistant material with Ultraviolet (UV) inhibitor,
high-grade Isophthalic Polyester Resin. The Fiberglass Reinforced Polyester (FRP) wall has a thickness no less than 1/4
inch; the fan duct is specially reinforced to ensure its structural strength. The Fan Duct contains a direct -drive fan, a motor
mounted on an FRP structure, and a corrosion -resistant safety screen mesh (also known as fan guard).
3.0 MECHANICAL EQUIPMENT
3.1 LOW SOUND FANS
The closed circuit fluid cooler has two 02 fan. Fan is direct -drive, with axial, sickle -shaped type fan blades. Fan blades are
manufactured of spark and corrosion resistant Fiberglass Reinforced Polyamide (PAG) and are suitable for operation on a
temperature range of-40 Deg. F (40 Deg. F) to 230 Deg. F (110 Deg. F). Fan hubs are manufactured of a pressure die cast
aluminum alloy.
3.2 FAN MOTORS
The closed circuit fluid cooler has two 02 fan motor, rated at 7_5 HP at 700 RPM. The fan motor is single speed, Totally
Enclosed Air Over (TEAO), and are suitable for 2301460 Volts, 3 phase, 60Hz service, continuous operation, 1.15 service
factor on sine wave, NEMA premium efficiency, severe duty — IP54, marine duty, and inverter rated. Fan motor's
construction is 100% cast iron and has Class F Insulation System. The fan motor meet NEMA MG1-1.26.6, has a Division
2 CSA certification nameplate for hazardous locations, Class I Groups A, B, C and D, and is Underwriters Laboratories (UL)
Recognized, and CSA Certified.
4.0 FILL MEDIA MODULES
Fill media modules are fabricated from rigid, corrugated UV protected Polyvinyl Chloride (PVC) sheets that are conducive to
cooling water. Polyvinyl Chloride (PVC) corrugated sheets form a cross -corrugated pattern with an angle of 60 degrees from
the horizontal between adjacent sheets, to provide a continuous and horizontal redistribution of air and water. Fill media
modules provide no less than 69 ft2/ft3 of surface area and a void -to -volume ratio of 95%. The manufacturing material,
Polyvinyl Chloride (PVC), are resistant to rot, fungi, bacteria and organictinorganic acids, and alkalis as commonly found in
closed circuit fluid coolers; and meet CTI STD-136. Fill media modules' flame spread rating is less than 20 according to
ASTM E84; and regarding flammability, fill media is self -extinguishing in less than 5 seconds according to ASTM D635.
5.0 DRIFT ELIMINATORS
Drift eliminators are fabricated from rigid, corrugated UV protected Polyvinyl Chloride (PVC) sheets and is furnished in
lightweight, easily removable sections with 2 changes in air direction to remove entrained water particles from the leaving
airstream. Drift losses not exceed 0.0005% of the design circulating flow. The manufacturing material, Polyvinyl Chloride
(PVC), are resistant to rot, fungi, bacteria and organicfinorganic acids, and alkalis as commonly found inclosed circuit fluid
coolers, and meet CTI STD-136. Drift eliminators' flame spread rating is less than 25 according to ASTM E84, and
regarding flammability, drift eliminators are self -extinguishing.
6.0 AIR INLET LOUVERS
Air inlet louvers are cellular type and designed to minimize splash -out of falling water, reduce light transmission into the,
closed circuit fluid cooler and reduce sound transmission out of the closed circuit fluid cooler at minimal airside pressure
loss. Air inlet louvers are fabricated from rigid, corrugated UV protected Polyvinyl Chloride (PVC) sheets and are easily
removable to provide access for cleaning. The manufacturing material, polyvinyl chloride (PVC), are resistant to rot, fungi,
bacteria and organic/norganic acids, and alkalis as commonly found in closed circuit fluid coolers, and meet CTI STD-136.
Air Inlet Lowers' Flame spread rating is less than 20 according to ASTM E84, and regarding flammability, air inlet louvers
are self -extinguishing in less than 5 seconds according to ASTM D635.

7.0 HOT WATER DISTRIBUTION SYSTEM
Hot water enters into the closed circuit Fluid cooler through a single inlet. Al interior distribution piping is Polyvinyl Chloride
(PVC) schedule 80 pipe. Water is evenly distributed over the fill media by removable 2 112 inch spray nozzles made of
Polypropylene (PP). Spray nozzles contain internal, interchangeable flow devices to provide an optimal spray pattern within
the 2 to 10 psig operating pressure range.
8.0 WATER DISTRIBUTION PAN
Cooled water is distributed externally overthe copper coil heat exchanger using gravity spray nozzles placed in a fiberglass
pan, so water is evenly spread across the copper coil for better heat transfer.
9.0 COOL WATER RECIRCULATION PUMP
Water is re -circulated to the water distribution system by a centrifugal, horizontal inline recirculation pump designed for
optimum performance, easy installation, and simplified maintenance. The close -coupled design results in improved
alignment and increased seal life.
10.0 COPPER COIL
The copper coil tubes are constructed of 518 OD Type L copper with excellent thermal conductivity, corrosion resistance,
and durability. It is encased in a stainless steel frame, leak tested at 300 psi, and uses 3 or 4 Victaulic connection depending
on the model.
