LOW NOISE FAN
Airfoil-shaped blades are totally fabricated from
fiberglass reinforced polyester (FRP) with an additional
epoxy coating for the resistance of ultra violet ray and acid
rain corrosion. The hubs are of cast aluminum alloy.
Blades with large chord are axial type with adjustable pitch for permitting
maximum utilization of rated horsepower and optimum performance. The aerodynamic
shape together with the lower tip speed ensure a lower noise level.

MOTOR AND DRIVE
The fan motors are totally enclosed fan cooled (TEFC) foot mounted with
weatherproof IP44 Class E insulation. The motors are mounted on an
adjustable base located inside the fan stack ensuring lower noise level.
The fans are vee-belt driven and are located in the bottle neck of
fan stack ensuring free and smooth air discharge and high efficiency
with low energy consumption. (IP 55 Motor can be provided upon request) |

3 IN 1 FILLER
Filler is vacuum-formed of 0.4mm thickness PVC film with excellent chemical
and high distortion resistance, and is suitable for operation with inlet
water temperature up to 55o C . Its compact package design is easier to
take out for cleaning. The special configuration of the filler incorporates
the function of drift eliminator, louver and wet-deck surface.
The honeycomb shaped louver feature contributes minimum resistance to
airflow and prevents the ingress of foreign matters. The drift eliminator
prevents water

DISTRIBUTION SYSTEM
FRP open type gravity flow hot water distribution trays are non-corrosive and long life, and are specially
designed for nonclogging operation and ease of inspection. A distribution cap is attached on top to
prevent water from splashing out and a redistribution layer of PVC mesh is placed on top of the
filler to provide full coverage of water distribution. |

STEEL STRUCTURE
All supporting steel members are hot-dip galvanized to minimize rusting
and corrosion ensure long service life even in corrosive atmosphere.
Stainless steel hardware members are also available upon request. |
|
 |
CASING AND BASIN
Casing and basin are made of FRP which excels in corrosion, chemical and weather resistance.
They are light weight and easy to assemble and obviates the need for painting, thus reduce
maintenance costs and guarantee long reliable service. |
|
 |
FAN STACK
Fan stack is made of FRP. The special aerodynamic design as
well as the location of fan provide more than 10% of motor
power saving. Furthermore, because of the longer stack, it
can discharge hot moist air away from the tower so as to
minimize the chance of re-circulation. |

 |
INSPECTION DOOR
Inspection doors are furnished to provide convenient access to the interior
for inspection, maintenance, adjustment of float valve, cleaning of the
lift-out strainer and flushing of the sump. |
