leading company and an ideal partner for you.
Performance in perfection.
Transformer cooling from ebm-papst
A well designed system
With our
fans for oil cooled transformer,you get a system with perfectly matched
components.The fans consist of a HyBlade impeller,a GreenTech AC motor and
electronics or an AC motor, a fan housing and a guard grill for the intake
side.They are avalaible in sizes ranging from 500 to 1,250mm.
All fan
designs are based on the requirements of the EN 50216-12 series of European
standards,which covers fans for power transformers.The grill provides contact
protection as per DIN EN ISO 13857.Their nozzles are made of hot dip galvanized
sheet steel on the out let side,they feature an integrated circumferential
flange that enables easy,direct attachment to the oil radiator.
Rugged and quiet with open loop
speed control
Super
efficient motors deliver top performance while consuming very little
energy.Aerodynamic optimization reduces air turbulence and minimizes noise.An
intelligent electronics ensure the ideal speed at all times for considerable
efficiency benefits,especially in partial load operation.Only the combination
of all these features ensures ideal cooling capability,and ultimately a
considerably longer transformer service life.
Incendentally,we
guarantes that you can rely on our measurements and characteristic fan
curves.We always test our fans as complete systems in our ultra modern test
labs under realistic operating conditions.So from us you get”real”measured
values and not calculated performance data
A perfect whole
The
venture housings of our fans provide a crucial advantage.The current industey
standard is to operate fans with a basket grill and without housing.in
addition,strong turbulence leads to high all performance losses.
As can be
seen in the diagrams below,venture housings provide higher air performance and
considerably better system efficiency.When fans are operated wide open(as is
typically the case with oil cooled transformers),the positive effects of a fan
housing are enormous.
Efficiency
meets innovation
The efficient heart:our Greentech
EC motor.
One reason
for the high efficiency of our fans is their GreenTech EC motors with external
rotor design.These are grid-powered permanently energized synchronous motors
with electronic commutation(also called BLDC).Their efficiency is well above
efficiency class iE4,but unlike many permanent magnet motors with internal
rotor design,they are not subject to the possible supply constraints associated
with rare earth magnets.
The EC
motors can be used worldwide and have all the required
approvals(UL,CSA,EAC,CCC),Not only does attaching the high performance impeller
directly to the rotor of the external rotor motor save space,it also allows the
entire rotating assembly to be balanced in a single procedure.

Good
to hear
Transformers
are increasingly used in the vicinity of residential areas,where strict
requirements related to noise must be met.To avoid causing sounds that can
disturb residents,noise generation must be minimized.speed reduction can be
used to adjust the noise level to requirements.During the day,the fans and the
transformer can work at full power.at night when there is less demand,all of
the fans can be operated at partial load.
In
conventional systems,individual fans are switched on and off.The fans that are
still running continue to work at full power,which is not ideal from the
perspective of overall system efficiency.This is where EC technology has a
significant advantage.
GreenTech
EC fans solve this problem more effectively with smooth speed adjustment at
sustained high efficiency keeping all fans in operation with significant
reductions in power consumption and noise,with a positive impact on the service
life of the fans.
A further
benefit of partial load operation is the more uniform air flow through a
transformer’s radiators,for more economical operation of the entire system and
improved life cycle costs.
The
diagrams below illustrate the potential energy savings and noise reduction in a
comparison of on/off operation and smooth speed adjustment.
Energy savings and noise reduction
in part load operation
Reduced energy consumption:The bars show the power
consumption of fans that are switched on stepwise as needed.Air performance is
reduced by 50% when half of the fans are switched off.The blue line shows the
power consumption of all fans with smooth speed adjustment at the required air
flow(50% air flow = only 12,5% input power).
Lower noise generation:While switching off half the
fans(50% decrease in air flow)only reduces noise generation by approx. 3 dB,a
speed reduction resulting in 50% less air flow achieves an improved of 15 dB.
