NIRON PP-RCT pipes and fittings 2", 3", 5" have been installed for the new air-conditioning system in Guardian Angels senior living house in Elk River, Minnesota. Once again, this system showed to be particularly suitable to be used in large buildings thanks to the special characteristics of its raw material. The pipes and fittings that compose the NIRON PP-RCT range are in fact produced using random copolymer polypropylene PP-RCT, a plastic material with a special molecular structure ensuring high mechanical resistance and duration, even at high temperatures and pressures. The properties and other features of the various components make the NIRON PP-RCT system a great alternative to traditional material used in plumbing installations. Its temperature/pressure performance allows for the use of thinner pipes thus offering a greater flow rate with the same diameter.
