Modern rail transport technology has a great demand for high-quality fans worldwide. Specially designed fans used in underground and suburban railways, regional and high speed trains for the cooling of traction engines, transformers, electronics and air-conditioners. Our fans have successfully been in use in these demanding applications on every continent since 1981 and meet the most diverse requirements with regard to mechanical shock, temperature range and power supply.
Customer specific developments enable a smooth operation also at:
- Voltage peaks
- High mechanical shock
- Varying weather conditions and thermal stresses
... and offer flexible solutions for:
- Optimal airflow
- Various operation voltages (at 50/60 Hz)
- Maximum efficiencies at variable speeds
- Minimum maintenance
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 systems, 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.
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 overheating the heat has to be dissipated. The same is true for components 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 field of 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 motorized 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.
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 sufficient heat dissipation is required to protect the sensitive electronic components. Our backward curved motorized impellers 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 propulsion system of trains, here system components which have to be cooled are used as well. For these cooling applications, our backward curved motorized impellers from the DKHR/M series (EC variant GKHR/M), centrifugal fans of the type ERA/DRA, as well as fans from the ECOFIT series REE, GDF and 200DW are used.
