The NIRON PPR system was used for the compressed air network and the glycol water cooling circuit of the Les Funambules microbrewery in Croix de la Rochette in France. The use of polyfusion welding without using glue or solvents made it possible to make the installation safe and durable. The installers appreciated the speed of installation. Les Funambules produces artisanal and organic beers at the foot of the Belledonne massif. 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.
