DESIGN |
 |
| |
 |
Delta's unique
aerofoil design
ensures high
efficiency, lower
noise levels and less
power consumption.
Reinforced Fibreglass
Epoxy Resin (FRP)
provides the desired
non-corrosive quality
to the fan blades,
resulting the
operation of fans even
in the very aggressive
environment.
Delta's light weight
FRP fans ensure a low
moment of enertia,
minimum wear and
stress on motor,
bearing and drive.
Hollow FRP blades
reduce material cost,
installation costs and
possibility of damage
to the fan and drive
during sudden stops. |

FLEXIBLE DESIGN
AND ADJUSTABILITY |
|
| |
Delta's FRP fans with
adjustable pitch
enables the
technicians or
engineers to change
pitch settings easily
in order to optimise
fan performance or to
change field
applications. |

UNIFORM VELOCITY |
|
| |
FRP cooling towers
have
Uniform velocity over
the entire blade area
is the most important
criteria of efficient
axial flow fan design.
To produce a uniform
velocity through out
its length, a fan
blade must vary from a
thin tip to a thick
cambered root. Each
point on the blade
must have the proper
combination of chord
(blade width) and
angle. This results in
a great deal of twist
in a properly designed
blade, a shape
impossible to produce by extrusion. The
Delta fan blades are
Jig-formed to provide
the complex contour
needed for high
aerodynamic
efficiency. |

Delta's fans are
electronically
balanced on
computerised balancing
machines to ensure
maximum output. |

Delta's fans are
available in the sizes
ranging from 3 feet to
30 feet diameter. Fans
of higher sizes can
also be provided on
request. |
