NIRON CLIMA PPR pipes Ø200mm have been used for the chilled water network in the renovation of the Gare de Namur railway station in Belgium. Gare de Namur is a railway station located in Namur north of La Corbeille, the historic city center. The railway track is located on an ancient arm of the river Sambre that once surrounded the northern bastion of the city and dates back to 1856. NIRON polypropylene pipes with fiberglass layer were designed to meet the demands of air conditioning systems but are now used in all applications where a lower thermal expansion and a greater resistance to expansion/contraction phenomena are required, thus guaranteeing greater dimensional stability of the pipe.
