NIRON pipes and electrofusion fittings 4" and 8" have been installed in Janesville, WI for the replacement of a chilled water system. NIRON pipes and fittings, particularly suitable to be used in large buildings, were selected thanks to the special characteristics of their raw material that ensures high mechanical resistance and duration, even at high temperatures and pressures. Today, PP-RCT NIRON can boast various installations in large collective buildings such as schools, colleges, hospitals and senior housing where cost & energy saving and safety are of primary importance.
