Fans for oil-cooledtransformers.
Full power for transformer cooling.

Transformers are increasingly installed in the vicinity of residential
areas, where strict requirements related to noise apply. In order
not to disturb residents, noise must be reduced to a minimum,­especially at night. Fans for transformer cooling must therefore
not only be robust and efficient, but also quiet and variable.
This is where fans featuring EC technology offer a significant­advantage: They are infinitely variable. During the day, the fans,
and the transformer, can work at full power, while at night whenthere is less demand they only operate at partial load.

2

The result is a substantial reduction in power consumption andnoise, while service life is significantly extended.
Moreover, installing the axial fan in a housing significantly
increases the air performance in the working area, because theair arrives e­ xactly where it is needed.

Everything you need for your transformer cooling.
The design of the fans was developed based on the requirementsof the EN 50216-12 series of European standards, which stipulates
fittings for power transformers – fans in particular. Their guard grills
provide contact protection as per DIN EN ISO 13857 and OSHA.
The fan housings are made of galvanized steel sheet. On the outletside, they feature an integrated circumferential flange that enables
easy, direct attachment to the application.

The ebm-papst solution offers significantly better air performance
than fans with no housing, resulting in much higher system efficiency.
