It has proven bacteriostatic properties, making it the ideal material for drinking water distribution, in order to prevent the growth of bacteria such as Legionella. During manufacture, the tubes are subjected to a patented treatment for passivation and stabilisation of the internal walls, thus assuring absolute compliance to the potability parameters required by European legislation for transported drinking water (European Directive 98/83 and Law Decree31/01). SMISOL® One copper tubing has a carbon residue C<0,06 mg/dm², much lower than that required by EN 1057 which defines a carbon content limit of C≤0,20 mg/dm².
The insulating sheath is in closed cell PE foam conforming to Reg. CEE/EU 2037/2000 (devoid of CFCs and HCFCs) with a green polyethylene corrugated film outer surface. Resistance to fire is class 1 compliant pursuant to Italian Min. Decree 26/06/84.
Thermal conductivity: λ ≤0,040 W/m°C.
Average sheath density: 30 kg/m³.
Min. sheath thickness: 6 mm (9 mm for the 22 x 1 mm diameter) under continuous laser gauge control.
Free of ammonia residues.
Excellent resistance to external chemical agents.
Class 1 non-flammable (Italian Min. Decree 26/06/84).
Free of CFCs and HCFCs (Reg. EEC/EU 2037/2000).
