PFC SERIES – PULTRUDED FRP COUNTERFLOW COOLING TOWERS
THE FUTURE COOLING TOWERS, BY‘TODAY’ Canara
Quality & Service with Integrity
ADVANTAGES OF PULTRUDED FRP STRUCTURE COOLING TOWER FEATURES
CANARA Designed & Manufactured India's first PULTRUDED FRP COOLING TOWER in the year 2000.Since then many Pultruded FRP Counter flow Cooling Towers have been installed in India & Abroad.
TOWER STRUCTURE
CANARA Towers are field erected, heavy duty counter flow cooling towers. Each cell size
can be designed up to 16 X 16 meters, to handle maximum water flow rate of 5000m³/Hr/Cell.
PFC series
Our versatile and efficient, pultruded fiberglass structure is
resistant to both chemical and biological attack, & offers an
environment friendly alternative, which features no chemical
leaching from the structural members into the circulating water.
Our Pultruded FRP members are manufactured confirming to standard
specifications & are classified as self-extinguishing and have a flame spread index of 25 or less, as per
In addition, all FRP members are manufactured using rich synthetic veil
as well as added UV inhibitors to protect against UV degradation. The connecting hardware and base anchors can
be supplied in S.S 304 / 316 or silicon bronze for sea water applications.
CTI-STD-137 and EN-13706
ASTM E-84-09. FR-Grade Isophthalic resin
Stainless steel fasteners are used throughout the cooling tower in conjunction with bearing sleeves to minimize
fiberglass shear stress in the bolted joints. If any member has to be replaced for any reason, its simple matter of
unbolting the structure and adding the new part.
MECHANICAL EQUIPMENT
The drive shaft is a single piece galvanized steel or stainless steel or of advance composite material design,
connected to flexible, self – aligning couplings. The drive shafts are dynamically balanced to minimize operating
vibrations. Each drive shaft is protected with 2 Nos. shaft guards to restrain the shaft in the event of a coupling
failure.
Pultruded FRP structure of the cooling towers, are completely assembled using SS bolt
nut washers. The Pultruded FRP is recognized as the best structural material for cooling tower
construction as it won’t corrode, rot, rust or warp at harsh environment.
PFC series
Pultruded FRP structural components are used throughout
PFC series cooling towers to produce an engineered Frame
work of unsurpassed strength, quality, reliability and safety.
Each Pultruded FRP member is pre fabricated as per
drawings and shipped to site for ready installation. Every Column
is anchored to the foundation to obtain highest structural stability.
The high efficient fan consists of multiple, manually adjustable
pitch FRP blades attached to a hot dip galvanized steel or S.S.
hub with S.S. hardware. The fan assemblies are statically
balanced at the factory.
The mechanical drive package consists of a right angled gear
reducer connected to an electric motor via a floating drive shaft.
An axial flow fan is mounted on the output shaft of the gear box.
The mechanical components are mounted on a torque tubesupport.
on the motor nameplate power for longer Gear life. The assembly is equipped with a vibration
cut – off switch. Lubrication oil Pipe line of the gear box is extended beyond the fan stack and includes a level
indicator, drain, dipstick and fill connections & a low oil cut out switch.
service factor
The spiral bevel gear reducers are designed in accordance
with standards and sized specially with a minimumAGMA 2.5
Normally, the motor is of the TEFC type with class F insulation, Class B rise, high energy efficient (Eff-1).
Nameplate power is selected with a minimum 1.10 safety factor applied to absorbed power at design conditions.
HIGH PERFORMANCE FILM FILLS
Generally, the most efficient film fill made
of PVC foils glued or buttoned together to
form blocks, which are mounted on Pultruded
FRP structural members. The fill covers entire
internal plan area of the tower.
Maximum performance fill designs and
non clog designs are available for wide range
of thermal and water quality requirements.
Our Design Engineers evaluate each cooling
tower application to select the best fill system
with maximum thermal performance and
minimum power consumption.
surface. The water distribution system requires very
little maintenance and nominal operating pump head.
Header pipe and lateral pipes are supported and clamped on
pultruded FRP channel supports.
Utilizes PVC 3 - Pass, drift eliminations offer the lowest drift rates in the industry with very low pressure
drop, reducing fan power requirements, thus saving energy cost. The drift eliminators are assembled into
removable panels using PP lock spacers.
The aero dynamically designed FRP Fan stack cum recovery cones, are constructed out of heavy ribbed
FRP panel segments bolted together. A full radius air inlet bell mouth is provided for smooth air flow into the fan.
The recovery cone flare angle is designed for velocity recovery of 75% of the difference in velocity pressure at fan
level & exit of recovery cone. The fan stack is designed for a wind load equivalent to the design wind load of the
cooling tower.
conforming to the specifications of .CTI - STD - 131
Pultruded FRP, antiskid type deck panels each of 24” wide, interlocked with each other and is bolted with
Pultruded FRP tower structure. Normally, the fan deck is designed for uniform load of 300kg /m .²
For poor quality water, splash fills like
splash grid, splash bars, trickle fill, turbo
splash fill etc are used.

ARCHITECTURAL TOWER CASING
Normally each cell has a FRP header
pipe coupled with PVC lateral pipes with non
clogging polypropylene nozzles which
distribute water evenly over the entire fill
The casing panels are normally of grey or beige colors. Colors of customer's choice can be offered.
