Airtècnics offers a complete range of fans for railway applications and provides efficient and high quality solutions, adequate to the specific characteristics of each vehiche used in ferrovial transportation.

Several manufacturers and suppliers from the ferrovial industry trust the fans designed and manufactured by Rosenberg Group. High quality fans, robust and durable that have been successfully used in these applications since 1981 and meet the requirements for mechanical shock, temperature range and power supply.

Airtècnics ventilation solutions for the railway sector ensure the optimal operating of the equipments in not optimal conditions, as tension peaks, high mechanical shock, oscillations, vibrations, adverse climatic conditions or thermal loads, as well as offering an optimal air circulation, the possibility to operate with a wide voltage range, maximum efficiency at variable speed and minimal maintenance.

Applications range for the ferrovial technology:

Air conditioning  of the driver's cab

The cab's workplace demands high technical requirements in terms of heating, ventilation and air-conditioning. For an optimal conditioning of the cabin are used ceiling mounted systems, roof-integrated systems or other systems below ground level.

Our high performance forward centrifugal fans of series DKHR / M (EC alternative GKHR / M) are ideal for the required air movement. ERA Centrifugal fans, the axial fans series AKF / AKS and the fans REE and VRE of ECOFIT series are also perfect for this application.

Cooling of driving and brake system components

Driving systems for railway applications, as traction or braking motors, store a great heat loss that has to be dissipated to avoid damages due to overheating. The same applies to the braking system of a railway vehicle.

The high performance forward centrifugal fans of series DKHR / M (EC alternative GKHR / M), the centrifugal fans ERA / DRA and the GDF fans of ECOFIT series are ideal for this applications.

Air conditioning for the passenger coach

Passenger comfort is a top priority in railway technology. Rosenberg fans are the right choice to ensure a pleasant air conditioning in the wagons.  We provide integrated compact solutions that reach the necessary operation point in a very reliable way taking up minimum space.

The high performance forward centrifugal fans of series DKHR / M (EC alternative GKHR / M), the highly efficient centrifugal fans of DRA series, centrifugal fans GDF series from ECOFIT and the axial fans AKF / AKS series fulfill the requirements for this application.

Ventilation of the switchbox cabinet / electronic cooling

Railway vehicles require many electronic components that are usually located in electrical boxes. It is necessary to control heat dissipation to protect electronic components that could be damaged by overheating.

Our high performance backward centrifugal fans series DKHR / M (EC alternative GKHR / M), our centrifugal fans with sliding characteristics ERA or centrifugal fans REE, GDF and 200D of ECOFIT series are perfect for this application.

Refrigeration of the components of the onboard supply 

The onboard supply system of the railway vehicles is provided with an accurate power source. As with the traction system for railway applications, here is also necessary to use high technology components  that shall to be cooled for an optimal functioning.

High performance backward centrifugal fans series DKHR / M (EC alternative GKHR / M), centrifugal fans ERA / DRA and the fans GDF from the ECOFIT series are ideal for these cooling applications.

The continuous information exchange among customers and factory engineers allow us to develop flexible and reliable solutions very quickly. We are pioneers in developing technological improvements and innovations in ventilation for the railway sector.
