NIRON electrofusion pipes and fittings 12" have been installed for a chilled water network at a Duluth Minnesota hospital. The old piping system had been deteriorating for some time now and creating many problems for the hospital. The NIRON range, particularly suitable for use in large buildings and for industrial installations, has been selected thanks to the special characteristics of their raw material which 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.
