NIRON PPR pipes and fittings by NUPI Industrie Italiane have been installed in the AYRE ATOCHA Hotel in Madrid for the plumbing, air conditioning and disposal systems. All cooling distribution lines have been installed using NIRON CLIMA PPR pipes. The heat distribution lines are served by the new NIRON FIBER BLUE PPR pipe diameter 125. Our distributor and its team of technical experts organized technical training and practical demonstrations about how to use the different machines. Clamps with noise insulation coating and EPDM rubber gaskets which allow a better sliding of the pipe were used for this installation.
