EC low-pressure axial fans
applications:
Our high-efficiency, energy-saving EC low-pressure axial fans
make
the most of their strengths wherever the focus is on high air
flow at
very low pressure, as in air-cooled heat exchangers, dry
coolers,
cooling towers and condensers. Typical areas where air coolers
are
used are mixed use or urban areas, for example to cool data
centers
in banks. These are areas where extremely strict rules about
noise
emission apply, so noise prevention plays a crucial role.
Perfect for the night shift: energy savings and noise reduction
in partial-load operation
Our GreenTech EC fan’s trend-setting technology provides a
crucial benefit, with stepless speed reduction lowering both noise
level and power
consumption. While the fans can deliver full air performance
during the day, at night they can all run at partial load due to
lower demand –
while retaining their high efficiency; all fans remain in
operation. The result: considerable reduction of both noise and
operating costs.
Always a step ahead.

Adjusting fan speed to operating requirements has two
important benefits. First, power consumption varies with
the cube of the change in speed. In numbers, that means
1/2 speed = 1/8 power or 1/2 air flow = 1/8 operating
costs. This relation is shown by the blue curve.
Second, noise emission decreases at a greater rate than
the decrease in speed (of air flow): 1/2 speed = -15 dB!
In a device with two fans, switching off one fan to reduce
the air flow by half would only reduce the noise level by
3 dB. The gray curve shows how the noise level varies
with the air flow.
The high-efficiency one-stop solution
Our new EC low-pressure axial fan uses only high-quality,
perfectly matched components. Its GreenTech EC motor, control
electronics and fan
housing from ebm-papst are combined with the FPX-impeller from
Howden in a ready-to-use fan that sets new standards. It is highly
efficient,
consuming less energy than comparable fans. It has significantly
lower noise emissions. It has undergone aeroacoustic testing as a
complete
unit on standardized test stands and has been completely
documented by ebm-papst. That saves you a lot of adjustment effort
as a single part
number covers all components that are relevant to your
particular solution.

Everything on board, ready for installation
Not only does combining the motor and the electronics in a
single unit save space, it also simplifies installation. The
perfectly adjusted system
makes additional filters and shielded cables unnecessary. And
the integrated control electronics replace an external variable
frequency drive.
As a result, expensive adjustments during installation and
grounding and shielding measures are a thing of the past for you.
Plug it in and turn
it on. That’s all.
Your contribution: Plug & Play.
Previous solution:
With the GreenTech EC solution from ebm-papst, you get…
… a complete system consisting of motor, impeller and
integrated variable frequency drive. All from a single source
and
completely configured. That means no additional components
and

legal
regulations according to the Ecodesign Directive for fans (ErP);
we
provide you with standards-compliant measurements and clear
documentation.
… maximum efficiency delivered by the GreenTech EC motor
with
integrated speed control.
... an integrated derating-function. Perfect protection

Dimensions
Data you can count on
Fan power measurements are carried out on state-of-the-art
chamber test rigs. The entire fan unit, consisting of motor,
control electronics and impeller, is measured in various
load
states. This ensures that we obtain reliable data, and that
you
can count on these values being reached when selecting a
fan.
So there is no chance of any nasty surprises when starting
up
the fans.
The measured data forms the basis for our design program,
which is available on request. This software can be used to
calculate the expected operating costs and to perform
lifecycle
cost analyses.
