1. Rosenberg has been developing and producing fans and air handling units for railway technology applications since 1981. Their fans are used for HVAC, cabinet cooling, equipment cooling, and other applications. 2. Their fans are customized for the demanding conditions of railway technology, including high shock stress, vibrations, and varying weather conditions. Their fans offer flexible solutions for optimal airflow, various operating voltages, maximum efficiencies at variable speeds, and minimum maintenance. 3. Rosenberg provides a wide range of fans suited for railway applications, including backward curved centrifugal fans, axial fans, and their ECOFIT line of compact fans. Their fans meet various industry standards for use in railway technology.

Air is our element – moving it intelligently and ef ciently is our
passion. Since 1981 we have been developing and producing speed-
controllable external rotor motors, fans and air handling units.
German Engineering skill is the basis of our development work and
drives our innovation. As a worldwide company we are represented
where our customers need us. With production sites and sales of -
ces in more than 45 countries we are present worldwide – a strong
and reliable partner always within reach of our customers.
Numerous manufactures and suppliers of the railway industry trust
in our fans. Through permanent and logical development we achie-
ve high quality improvements for our products. The continuous ex-
change of information between customers and factory engineers
enables us to develop flexible and reliable system-solutions quickly.

Fans for Railway application
HVAC - Heating, Ventilation and Air Conditioning
HVAC units are necessary to guarantee proper air quality in both
the driver’s cabin and the passenger’s compartment. Rosenberg
fans help to provide the right air climate in trains and are used as
condenser, evaporator, exhaust and supply fans.
Cabinet Cooling
Most of the functions which are not directly related to the driving
process are controlled by electronics built in switch gear cabinets.
To protect the electronics and the entire cabinet system from over-
heating, Rosenberg fans are used to cool down the cabinets.
Equipment (Rack) Cooling
Heat generated by various components like traction converters,
auxiliary converters and battery chargers need to be cooled to en-
sure proper function of the train. Through removing the dissipated
heat and simultaneously providing ambient air to the equipment
it is possible to build more compact and powerful equipment. In
order to cool power electronic stacks in an efficient and silent way,
Rosenberg fans are perfectly suited.

Fans for Railway application
Air conditioning of the driver’s cab
The workplace of the train driver places high technical demands
on heating, ventilation and air-conditioning. Whether on-roof sys-
tems, integrated roof systems or under floor installations – for the
required air movement our backward curved motorized impellers
from the DKHR/M series (EC-variant GKHR/M) are ideally suited.
Also centrifugal fans of the type ERA, axial fans from the series
AKF/AKS as well as fans from the ECOFIT series REE, GDF and VRE
are eminently suitable for this application.
Air conditioning of the passenger cabin
Comfort for passengers is a top priority in railway technology. Fans
of the Rosenberg group are the right choice for a pleasant climate
in the cars. They reach the required operating point within inte-
grated system solutions reliably at minimum space requirements.
Such characteristics have for example our backward curved moto-
rized impellers from the DKHR/M (EC-variant GKHR/M), centrifugal
fans of the type DRA, centrifugal fans from the ECOFIT series GDF,
as well as AKF/AKS axial fans.
Cooling of components of the propulsion- and braking system
The traction system of a rail vehicle consists of different elements
like tractions motors and traction inverters. To avoid harmful over-
heating the heat has to be dissipated. The same is true for compo-
nents of the braking system of trains. Backward curved motorized
impellers from the DKHR/M series (EC-variant GKHR/M), centri-
fugal fans of the type ERA/DRA, as well as centrifugal fans from
the ECOFIT series GDF are best suitable for this eld of application.

Switch gear cabinet ventilation / electronics cooling
The technical constructions of rail vehicles consist of many elec-
tronic components which are often housed in switch gear cabinets.
Here too suf cient heat dissipation is required to protect the sen-
sitive electronic components. Our backward curved motorized im-
pellers from the DKHR/M series (EC variant GKHR/M), centrifugal
fans of the type ERA or fans from the ECOFIT series REE, GDF and
200DW were especially designed for this application.
Cooling of components of the onboard power system
High precision power supply within the onboard power system of
rail vehicles is state-of-the-art today. Comparable with the propul-
sion system of trains, here system components which have to be
cooled are used as well. For these cooling applications, our back-
ward curved motorized impellers from the DKHR/M series (EC vari-
ant GKHR/M), centrifugal fans of the type ERA/DRA, as well as fans
from the ECOFIT series REE, GDF and 200DW are used.
