PP-RCT NIRON 6" pipes and fittings have been installed in the new High School being built in Sartell, MN for both chilled water and heating lines. The AHU's sizing is 3" and 4" both for chilled water and heating lines. Once again, this system showed to be particularly suitable to be used in large buildings and NIRON pipes and fittings were selected thanks to the special characteristics of their raw material. PP-RCT NIRON has become a recognized and trustworthy product range and has already been installed in various schools and colleges where safety and efficiency are of primary importance. Here are just some examples: Seminole State College in Sanford (FL), East Carolina University in Greenville (NC), Apollo High School in Saint Cloud (MN), Phillips Academy in Andover (PA), Sherwood Forest Elementary School and Paul Habans Charter School in New Orleans (LA).
