Fan manufacturer Etri, based in France has been supplying standard and special fans for over 50 years. Etri is renowned for their experience within the railway industry and can supply a wide range of products for various rail applications, including cabin air conditioning, electronic cooling, and extraction systems.
The company has also recently developed a special fan for a very special railway application. Trains operating in extreme climates like Siberia have issues starting in the morning; particularly when the thermometer is around -40°C.
At these temperatures, most of the locomotive is completely frozen and will not start. The Etri 856DW is designed to blow air against a heater which will slowly preheat the locomotive.
The fan is fitted with Ø350 backward impeller, powered by 1.3kW motor 72VDC. The winding is protected to Class H for insulation. The maximum airflow is 1800m³/h and maximum pressure at nearly 2000Pa. For more information about Etri products and technical advice, contact Axair today.
