HYDRAULICS & PNEUMATICS EXPLORE AN ECOLOGICAL FUTURE Electric vehicles are gaining momentum around the world, with more and more major cities increasingly switching to electric buses for public transport. The global Dürr Technik Group devotes itself to all aspects of “e-mobility” and has developed oil-free compressors that are powered by their own electric motor(s). These compressors offer energy savings with fewer pollutants in the “Automotive” sector. Precision fluid system components For vehicles over 3.5 tons, a reliable and robust compressed air supply is essential - for applications ranging from brake release air to door opening to air suspension. Instead of mechanically connecting the existing compressors with the vehicle engine in a conventional manner, the newly developed and efficient Dürr Technik compressors have their own electric motor(s). These are extremely environmentally friendly, run independently of the vehicle engine and only draw power when needed, meaning the a very low energy consumption. The compressors that we manufacture are oil-free meaning oil control or oil changes are a thing of the past. Coupled with their compact and robust design, very low noise / vibration, low whole life costs, ease of installation and the fact that they are almost completely maintenance free, they can be installed into many positions within the vehicles that would have been impossible in the past. Depending on the product selected our compressors can achieve temperature ranges of between -40 and +40OC and can be operated with a duty cycle of 100 percent. The compressor B-304 WR from Dürr Technik is especially suitable for vehicles with a total mass of up to 13.5 tonnes. With a centralised air intake system, this allows flexibility of installation to suit the manufacturers requirements. For vehicles over 13.5 Tonnes, the E-Bull-300 from Dürr Technik is the ideal choice. At 400 V and 50 Hz, the compressor delivers 280 l / min at 10 bar - at a sound pressure level of 72 dB (A), similar to a vacuum cleaner. With the E-Bull-300 weighing in at only 45 kg, with dimensions of 474 x 286 x 496mm and an IP67 rating it is suitable for all types of vehicle. In addition, Dürr Technik can make individual adjustments to suit specific customer requirements. Durr Technik pride themselves by offering complete solutions with dryers, after coolers, ambient cooling fans, support brackets and enclosures as required.
