Crown
A highly flexible, pre-insulated pipe system with two heat transfer tubes (flow and return) in the same outer casing, mainly used to transport heating water, domestic hot water or other fluids in underground networks.
Heat transfer tubes are made of PER-a cross-linked polyethylene with an oxygen barrier, orange for the flow and blue for the return. This difference in heat-transfer tube color makes it easy to identify flow and return tubes, even when dust covers or heat-shrink sleeves are fitted.
Thethermal insulation, consisting of several layers of microcellular cross-linked polyethylene foam with a closed-cell structure, is totally waterproof.
