NIRON All PRO preinsulated pipes and fittings and NIRON CLIMA pipes installed underground at a major hosptal project in southeastern U.S. involving 2 - 20” uninsulated NIRON Clima pipes for chilled water lines. The project also involved 2" to 14” All PRO preinsulated heating lines from thew central utility plant. This work was completed ahead of schedule and the contractor was thrilled with the gain in efficiency, thanks to NUPI outstanding product ranges. NIRON All PRO is the innovative preinsulated PP-RCT pipe and fitting system that is ideally suitable for applications in areas where the heat loss reduction is essential. This product range was specifically designed for networks for the distribution or adduction of hot fluids. The reliability, ease of installation and relevant physical-mechanical properties of the materials used allow installers to avoid many problems when installing heat distribution and conditioning systems. The possibility of burying pipes directly eliminates high masonry costs. In tunnels or manholes the full tightness ensures durability. Moreover, ease of installation allows substantial time savings. This excellent characteristic of the material allows to obtain high levels of thermal insulation with significantly reduced insulation layers if compared to those that would be required if other materials were to be used. 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.
