The NIRON PPR system was installed in a pharmaceutical plant in Bresso, Italy. 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.
