This copper tube is manufactured according to the EN 1057 standard, pre-insulated during production with expanded polyethylene with a closed-cell structure of regular and uniformly distributed dimensions. The insulating sheath is also protected externally by a special polyethylene film. Insulated according to Law 10/91 and its implementing decree (DPR412/93), for the distribution of the heat transfer fluid inside heated environments. The insulating sheath is produced in full compliance with European Regulation EEC/EU 2037/2000 which requires the use of expanded insulating sheaths without the use of CFCs and HCFCs, gases harmful to health and the environment.
