EsencoRICEMedicaLLevel Wound CoilCoated

 

TEN, a copper tube pre-insulated with low-density closed cell expanded polyethylene, in compliance with Law 10/91, former Law 373, regarding the design, installation, running and maintenance of thermal systems for buildings, for the purposes of energy consumption control.

Ideal for water distribution systems, classified in fire resistance class 1, the coating has been designed in the smallest details to respond excellently to the increasingly more qualified requirements in the design of modern plants.

The protective film is corrugated to provide greater adherence to cement mortars and has an excellent resistance to external agents.

The coating is odourless, non-toxic and is made without the use of CFC. It is suitable to be used in plants with operating temperatures ranging from -30°C to +95°C.

The TEN copper tube is supplied in 50-meter coils (25 meters with Ø 22 mm)  marked at intervals also indicating the relative meters. 

The core of the TEN  is the ESENCOR copper tube, providing excellent protection against corrosion, the result of scientific studies and tests that guarantee a considerably lower level of residual carbon than is required by  manufacturing standards.
