The NIRON PPR CLIMA system SDR11 was installed at ITSE, the Highly Specialized Technical Institute in Panama. The installation using a pre-insulated system for the transport of chilled water was considered to be the most suitable solution for a system that presented adverse conditions due to the characteristics of the unstable and stony ground. One of the key elements that allowed to meet the deadlines for the completion of the works was to provide the working teams with professional machinery and technical assistance on site. NIRON CLIMA is available in large diameters, minimises condensation and prevents corrosion. NIRON is a complete polypropylene pipe and fitting system for the distribution of hot and cold water in plumbing and air conditioning systems, for the conveyance of drinking water and alimentary fluids, industrial plants and for the transport of compressed air and chemical substances. The pipes and fittings that compose the NIRON range are manufactured using random copolymer polypropylene (PPR and PP-RCT), a plastic material with a special molecular structure ensuring high mechanical resistance and duration, even at high temperatures and pressures.
