Energy Saving Fans for Cooling Towers & Air Fin
Coolers
Air Fin Coolers and Cooling Towers
Because of their apparent simplicity, Air Fincoolers and
Cooling Towers are all too often taken for granted to
provide the desired lower return temperature.
These are high energy utilization machines as well as
Heat & Mass transfer Devices.
The following need to be highlighted for scope of
Efficiency Improvement:
Knowledge of the actual performance in relation to the
Design.
Critical component(s) of the system.
Awareness of the efficiency levels in latest and proven
technology.
Options or potential of design modification.
Selection & Adoption of Reengineering methodologies
to achieve sustainable solutions.

Leading Edge
The drawing above represents a front elevation of a blade blowing upward, rotating toward
the observer about the center line of the driving shaft, shown at left. The leading edge is
assumed to be straight and the increase in required width as the center is approached is
taken up by the trailing edge.

Blade Design
ADVANTAGE OF HOLLOW FRP BLADE FANS
Optimal aerodynamic design of fan impellers to provide higher efficiency for any specific application.
Reduction in overall weight of the fan, thereby extending the life of mechanical drive system.
Requires lower drive motor rating and light duty bearing system.
Lower power consumption resulting in appreciable energy savings.
FRP fan fabricated compression molding / resin transfe molding technique would have uniform dimensions and consistent quality.
Lower flow noise and mechanical noise level compared to conventional metallic fans.
Longer life of the fan due to improved mechanical strength.
