The NIRON system diameter 22" and down has been installed for the Hines Veterans Administration Hospital project for condenser water in Illinois. Electrofusion fittings have been welded directly on site quickly and safely and prefabricated manifolds produced at the NUPI plant in Early Branch in South Carolina were used.The Edward Hines Jr. Veterans Administration Hospital is a second-generation Veterans Health Administration hospital in Hines, Illinois. It currently encompasses 174 acres (70 ha) on its campus and leases an additional 60 acres (24 ha) to the Loyola University Medical Center. Construction began in 1918 on land donated by the Edward Hines Lumber Company that was originally Speedway Park, a board track racecourse. The building was originally intended to house casualties from World War I, and Hines wanted the building to serve as a hospital after the war. Hines was successful in lobbying the United States Congress to take over the facility as a veterans hospital in 1920. In 2013, 45 acres (18 ha) of the campus, including the Old Airmail and Postal Service Buildings from the Maywood Air Mail Field, were listed on the National Register of Historic Places as a historic district.
