The NIRON PPR system was installed for a chilled water network for an industrial plant in the Loire Atlantique. This professional refrigeration specialist chose our NIRON PPR polypropylene piping system thanks to its advantages, i.e. the reliability of the junctions by butt fusion or electrofusion welding and the speed of installation. NIRON is a complete polypropylene pipe and fitting system for the distribution of hot and cold water in plumbing and air conditioning systems and for the conveyance of drinking water and alimentary fluids in industrial plants. 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.
