NIRON COOL PRO pipes and fittings Ø315mm for the transport of cold water (cooling towers) at a data centre in Italy. The advantages of a white anti-UV layer include UV resistance, thanks to the particular external white PP-RCT which acts as a photoprotector by inhibiting the UV rays’ degradative action on the underlying polymer, UV reflection with lower temperature difference thanks to the external white protection, as we assist to a lower absorption of the solar radiation and resistance to stray currents, thereby avoiding the risk of perforation of the pipe or fittings caused by stray currents, because polypropylene is a very poor electrical conductor.
