Made in accordance with the applicable rules and law no. 46of 5th March 1990 and Presidential Decree no.1095 dated 3rd August 1968, it is an LWC CU DHP copper alloy pipe complying with European Standard EN 12735-1, with inside surfaces, cleaned annealed in coils and phosphorous deoxidized, with minimum 99.9% copper content and 0.015-0.040% phosphorous, in compliance with UNI 56491n series B, heavy, bearing the marking “Manufacturer D x thickness OD x thickness I 00” or “ Manufacturer ACR”.

After inside surfaces are thoroughly cleaned and tubes are closed at the ends to keep the pipe clean until it has been installed, the copper pipe is subjected to a process that produces around it a layer of a special product (the connection of the two products is patented) specifically studied and manufactured to isolate tight and homogeneously the tube from any contacts with the environment, avoiding any substance to come in a direct contact and hence taking away any possibility for corrosion coming from outside (for instance “formicary corrosion”).

Covered with a low-density closed-cell polyethylene foam sheath that is finished with an outer clear grey LDPE extruded film and embossed to ensure improved mechanical protection and appearance. It is non-toxic, odourless and free from chlorofluorocarbons (CFC), anticondensate. This ISOCLIMA insulating sheath, which adheres to a non-flammable base, melts flamelessly and thus belongs to self-extinguishing BL S2 D0 (EN 13501) and bears the progressive marking"00 ISOTECH OD x thickness BL S2 D0 suitable for R407/R410/R32" as well as an indication of the date, time and production line for quality controI purposes. The main features of the ISOTECH 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.

"ISOTECH" by ISOCLIMA is mainly used far conveying refrigerant gases in split systems.
