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.
Characteristics
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 ever more qualified requirements in the design of modern heating systems.
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 CFCs. 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-metre coils (25 metres with Ø 22 mm) marked at intervals also indicating the relative metres.
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.
Supply
The copper tube EN 1057 is marked СЄ as required by EU 305/2011 EU Construction Products Regulation (CPR).
