NIRON piping system was installed in Glenridge Middle School Construction in Landover, Maryland. The network includes a geothermal hydronic system with some ELOFIT couplings for the HDPE used for the underground. All NIRON was installed for the aboveground network in the school. The system was under a successful 150PSI hydrostatic test while on site. The NIRON range, particularly suitable for use in large buildings and for industrial installations ensures high mechanical resistance and duration, even at high temperatures and pressures. NIRON has become a recognized and trustworthy product range and has already been installed in various schools, colleges, hospitals, senior housing buildings, apartment buildings and industrial plants where safety and efficiency are of primary importance.
