6 HUBER Heat Exchanger RoWin 14 for the new La Saulaie district in Lyon


In the south-west of Lyon, France's third largest city, the new modern La Saulaie district is currently under construction. It will provide new flats and houses for more than 2,000 people as well as commercial space, parks and leisure facilities. The existing district on the banks of the Rhône is being modernised and extended on the currently unused site of the French railway company SCNF.
Sustainable energy supply
As the issue of sustainability plays a similarly important role in France as it does in Germany, a sustainable energy supply for the district was particularly important to the project developers from the city of Lyon. The nearby sewer offers ideal conditions for the district’s heat supply. The Engie SA group had already been awarded the contract as energy supplier in 2021.
HUBER technology for energy recovery
In the planning phase, HUBER was able to score with reliable machine technology and more than 14 years of experience in the field of energy from wastewater. Our subsidiary HUBER France received the order for the supply, installation and commissioning of six HUBER Heat Exchangers RoWin14 in 2024.
