Fan units
A
xial
fans
mounted
in the roof
of the tower
serve
to create an
air draft
inside cooling tower
.
We provide design
and delivery
of appropriate types
of fans
from leading manufacturers
in diameters ranging from
0.6 m
to
12 m
.
The fan blades
are made of
composite (
FRP)
and
possibly
aluminum alloys
fitted into
central hubs from
galvanized
steel.
C
omposite blades
enable advanced
shaping
of the airfoil profile
and
provide low weight
and high strength
.
The fans are driven
by asynchronous electric
motors
.
The electric motor
may be connected
with fan
directly (
i.e.
in the case of
multi-pole
motors with
low speed
output
shaft)
,
or
via
reducing
gear
.
Common
is management of rotation speed by
the VFD
when the
potential annual savings
of el
.
energy
up to 40
%
.
