The system was used for heating water diameter 20mm and 160mm, chilled water diameter 25mm and 75mm and domestic hot & cold water diameter 20mm through 200mm. NIRON PP-RCT is a pipe and fitting system produced using a special random copolymer polypropylene with a special molecular structure ensuring high mechanical resistance and duration, even at high temperatures and pressures.
