Asahi/America’s Asahitec PP-RCT piping systems for plumbing and HVAC applications are an advancement in polypropylene polymers and offer a wide range of benefits including greater pressure capabilities at higher temperatures than conventional PP materials. The two systems are: Climatec for hydronic heating applications and Watertec for potable water. Pipe in both systems is manufactured with patented Fibercore technology, which minimizes expansion and contraction by up to 75%, in turn reducing installation costs by minimizing expansion loops and supports.
