Knorr-Bremse at InnoTrans 2016: in tune with the times
October 13, 2016 [Knorr-Bremse Group]
Knorr-Bremse can look back on a very positive InnoTrans fair: “An overwhelming level of interest among trade visitors, crowds of people at our booths, numerous high-level meetings, various contracts signed, and an award from Russian Railways – that sums up InnoTrans 2016 for Knorr-Bremse,” says Klaus Deller, Chairman of the Executive Board of Knorr-Bremse AG and responsible for the Rail Vehicle Systems division.
“With our focus on the topic of Connected Systems, we were totally in tune with the times in the railroad industry, where everything now revolves around digitization,” Deller explained. “By providing smart, connected subsystems we offer manufacturers and operators safe, reliable and efficient solutions for high-performance rail transportation.” On five booths covering 800 square meters, Knorr-Bremse presented a broad cross-section of its product portfolio. Among the prominent visitors to the booths were Alexander Dobrindt, German Federal Minister of Transport and Digital Infrastructure, and the Chairman of Deutsche Bahn AG, Dr. Rüdiger Grube.
Trade show visitors showed strong interest not only in the latest brake control systems, bogie equipment, connectivity solutions, and new air supply system from Knorr-Bremse, but also in the systems showcased by the Group’s subsidiaries. Examples here included the new entrance system for mass-transit applications presented by IFE, with opening and closing times of less than two seconds, as well as the adaptive HVAC system for light rail vehicles displayed by Merak. This system automatically adjusts its output to the volume of passengers in the vehicle, thereby ensuring optimum energy efficiency.
“The digitization of the rail industry has also impacted on RailServices,” reports Dr. Martin Lange, Chairman of the Management Board of Knorr-Bremse Systeme für Schienenfahrzeuge GmbH. “In particular, solutions that deliver energy savings and enable condition-based maintenance are in great demand.” This trend was reflected in two agreements with Nedtrain that were signed at the fair. Nedtrain is responsible for the maintenance and inspection of trains operated by Dutch Railways. The agreements cover a development part-nership focusing on the condition monitoring of oil-free compressors using iCOM Monitor, as well as a shop-in-shop concept complete with exchange of experience and staff training. Irrespective of the vehicle platform, this application enables operators to carry out cost-effective, condition-based and preventive maintenance on their fleet of vehicles as required.
During the fair, Knorr-Bremse’s Russian subsidiary Knorr-Bremse 1520 received an award from Russian Railways (RZD) for the KAB60 distributor valve. The KAB60 valve is specifically designed to meet the requirements of the GOST standard and is installed in newly developed RZD vehicles. RZD honored the valve’s performance and contribution to cutting life cycle costs with a “Best in Quality, Components for Rolling Stock and Infrastructure” award.
Knorr-Bremse PowerTech presented itself at the world's largest rail vehicle trade fair on 109 m² in Hall 17 in close proximity to the Knorr-Bremse subsidiary Microelettrica. Out of the PowerTech portfolio of standardized and modularized on-board power converters for all train types and performance categories, the following products were presented during the InnoTrans:
The EMU Toluca 135 kVA auxiliary power converter for a multiple unit project in Mexico designed for an input voltage of 1,500V DC. The trade fair visitors were able to experience the lightweight and compact design thanks to medium-frequency electrical isolation. A great deal of interest was aroused by the modular design, which allows easy maintenance as well as the low noise, thanks to continuously speed-controlled fans. A further special feature is the operation altitude of the inverter. It differs from the normal operating conditions (1400 m above see level (NN)) and can be up to 3100 m above see level (NN).
The auxiliary power converter iAC (intelligent Air Control) used for the supply of equipment for air supply compressors also attracted the interest. The visitors were able to convince themselves that the combination of inverter and air compressor offers the operator a decisive added value, especially with regard to maintenance and lifetime costs. The air compressor is thereby operated in variable speed, according to the air requirement, which significantly reduces noise and abrasion.
Furthermore, Knorr-Bremse PowerTech exhibited a lightweight, low-noise 75 kVA auxiliary power supply unit adapted to fit the specific needs of Chinese light rail vehicles. The inverter type is equipped with a redundant battery charger module and a dead battery start functionality. In the event of a battery charger failure, the on-board power supply and the battery charging funcionality are taken over by the second device without any interruption. This ensures a 100% availability of the vehicle. The electrical design has been specially adapted to meet the requirements of the Chinese tram market.
The business unit for converters in the field of Industry and Energy within PowerTech also took the opportunity to meet a wide range of customers, as the interest in industrial converters for railway applications is growing - e.g. for test bench applications or energy storage solutions.
