KLINGER Fluid Control ball valves are key to La Défense’s energy upgrade, increasing efficiency and sustainability.
Idex La Défense, the operator of the district heating and cooling network for Europe’s largest business district, La Défense in Paris, has embarked on a major upgrade to improve its energy infrastructure. With the construction of Metro Line No. 15 for the Grand Paris Express, Idex needed to relocate and expand its pipe diameters to improve network performance and serve a growing customer base. Key to the project are valves supplied by KLINGER Fluid Control, which were meticulously tested at the company’s facility in Gumpoldskirchen, Austria, to ensure they met stringent specifications for safety, reliability, and durability specifications.
As part of the construction of the Grand Paris Express, Idex La Défense is upgrading its heating and cooling networks by replacing pipes with larger diameters to enhance system efficiency and meet increased demand. For the hot water network, the pipes have been increased to DN400, while the cooling water pipes have grown to DN800.
To meet these new requirements, KLINGER Fluid Control supplied several units of the KHSVI ball valves. Specifically, the hot water network now includes four DN400 and two DN300 valves, all capable of operating at 190°C and 25 bar pressure. The cooling water network, scheduled for installation in 2025, will include four DN800 valves, which are designed to operate in cold conditions of 4.5°C at 16 bar.
