NIRON pipes and electrofusion fittings from ¾” to 2" have been installed for the transport of hot and cold water for the HVAC system in Boston Harvard Medical School. Harvard Medical School is one of the graduate schools at Harvard University. The institute was founded on September 19, 1782 by the famous surgeon John Warren, becoming the third, in chronological order, between the medical research institutes of the United States of America. The first lessons were held in the underground halls of the Harvard Hall and later in the Holden Chapel, a small chapel inside the university complex. At first there were only two students who graduated in 1788. The NIRON range 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.
