Made in accordance with the applicable rules and law no. 46 of 5th March 1990and Presidential Decree no. 1095 dated 3rd August 1968, it is an LWC CU DHP copper alloy pipe compling with European Standard EN 12735-1, with insidesurfaces, cleaned - annealed in coils and phosphorous- deoxidised, with minimum 99.9% copper content and 0.015-0.040% phosphorous, in compliance with UN1 5649/77 series B, heavy, bearing the marking "Manufacturer name D x thickness EN 12735-1 SLM I 00".

The inside surfaces are thoroughly cleaned and plugs are fitted at the ends to keep the pipe clean until it has been laid. Covered with a low-density closed-cell polyethylene foam sheath that is finished with an outer white LDPE extruded film and embossed to ensure improved mechanical protection and appearance. It is non-toxic, odourless and free from chlorofluorocarbons (CFC) with thicknesses compling with law no. 10/91.


The Isoclima insulating sheath, wich adheres to a non-flammable base, melts flamelessly and thus belongs to self-extinguishing CLASS 1 (UNI 9177-87) and bears the progressive marking "00 ISOPOLAR D x thickness CL.1 EN 12735-1 suitable R407/R410/R32", as well as an indication of the date, time and production line for quality control purposes. The main features of the Isopolar sheath are excellent to water vapour, significant reduction in moisture on the outer surface of the pipe when supplying water at dew point temperature in air at ambient temperature.


Isopolar is mainly used for conveying cooolant gases in split systems.
