The compact, dual-flow centrifugal blower has especially high-performance integrated electronics and guarantees maximum reliability in a compact package – and not only for indoor use.
The centrifugal blower is now available for 110 VDC and no longer only for 24 VDC, so it can be directly connected to existing 110 VDC on-board electrical systems without the need for a voltage converter.This makes it ideal for cooling variable frequency drives in railway applications.Its integrated MODBUS interface ensures trouble-free operation (parametrization) and data retrieval for operational status monitoring.The blower is easy to install with plug & play connection.It satisfies the requirements of the highest protection class, IP69K (dust-proof), and the motor is protected against water ingress during high-pressure cleaning.
The DC motor used in the blower is highly versatile.The motor’s design allows it to be used in dual-flow centrifugal blowers as well as in axial fans or single-flow blowers.The control and motor characteristics and the connection mechanism remain identical, regardless of the impeller it is combined with.Once validated, a motor can be quickly and economically put to use in a wide range of applications, including air conditioning applications in the driver’s cab and passenger compartments.
The European standard EN 45545 for fire protection on railway vehicles has been in full force for some time.The seven-part standard has the objective of protecting passengers and staff in case of fire on board and assuring evacuation.The fans from ebm-papst satisfy the requirements for Hazard Level (HL) 3 of the EN 45545-2:2013 standard.In addition, all ebm-papst fans for railway use are designed according to EN 50155:2016 (electronic equipment used on rolling stock).
This and other ebm-papst products can be viewed at InnoTrans(Berlin, September 18 – 21, 2018) in Hall 3.1 at Stand 230.
