The Expo Explorer visitor train powered by BAUER high-pressure air

At Expo Dubai, over 24 million visitors from 178 countries seized the opportunity to take a fascinating look into the future of humanity. The BAUER GROUP occupied various pavilions presenting an ultra-sustainable and innovative mobility solution. 

At this trade show and parade of superlatives, 200 participants from 192 different countries introduced the latest developments in the fields of digitalization, sustainability and mobility. Themed weeks showcased a wide variety of different areas including climate, biodiversity, urban space development, space exploration and artificial intelligence (AI). In a particularly sustainable mobility project, BAUER GROUP subsidiary BAUER COMPRESSEURS had organized excursion trains powered by compressed air instead of fossil fuels or batteries, which chauffeured visitors around the exhibition centre grounds. 

It was the excellent reputation of its compressor systems that clinched the contract for this prestigious project for the BAUER GROUP. To produce the highly compressed air required for the powertrain, BAUER COMPRESSEURS joined forces with the local subsidiary, BAUER KOMPRESSOREN MIDDLE EAST to develop a bespoke turnkey solution comprising three high-performance, high-pressure I 28.0-75 compressors combined with a large-scale 350-bar storage bank. This system, with 106 (!) 50-litre steel storage cylinders, ensured a constant supply of the air volume necessary for operating the trains, including reserve and buffer storage.. Coupled with a rapid charging station, the system enabled a full train to be “fuelled” with 1600 litres of compressed air at 250 bar in under ten minutes.
