NIRON All PRO electrofusion pre-insulated pipes and electrofusion fittings are fast and easy to install with no mess lightweight material handling and are made in South Carolina and shipped ready to install. Recently a mechanical contractor installed underground chilled water supply and return from inside of a city building in Port Allen, LA to cooling tower pads before they poured concrete. The customer was trained as a first time installer on site and built the spools while they were being trained. 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.
