NIRON Beta pipes and fittings SDR11 Ø90-315 and PPR pipes and fittings were installed for a geo-exchange system with groundwater in Milan serving a multi-storey office building. The filtering plant and the manifold connects with the wells up to the connection with the exchanger of the thermal power plant. NIRON Beta pipes are more resistant to chemicals and to thermal shocks. They can therefore be used for distribution networks where chlorination is used and where the water temperature is higher or for the transport of osmotic water. The NIRON Beta range, particularly suitable for use in large buildings and for industrial installations ensures high mechanical resistance and duration, even at high temperatures and pressures. NIRON Beta has become a recognized and trustworthy product range and has already been installed in various schools, colleges, hospitals, senior housing buildings, apartment buildings and industrial plants where safety and efficiency are of primary importance.
