Pre-flared coupled pipe, for split systems and heat pumps. Suitable for R407/R410/R32 gas
Pre-insulated and flared coupled copper tube supplied with fittings produced in compliance with current regulations and in reference to the Ministerial Decree. 37/2008 and compliant with energy saving regulations such as Law no. 10/91, Presidential Decree 412/93, Legislative Decree 19 August 2005, no. 192 and Legislative Decree 29 December 2006, no. 311.
La tubazione di rame è conforme alla UNI EN 12735-1:2020 “tubi di rame tondi per gli impianti di condizionamento e refrigerazione” ed è costituita da una lega CU-DHP, ricotta in rotoli disossidati al fosforo, con tenore di rame minimo 99,9% e di fosforo compreso tra 0,015% e 0,040%.
Based on the aforementioned elements, the copper tubes of the TWINpolar FN product are suitable for the passage of refrigerant gases such as R407/C, R410/A and R32.
Covered with a low density closed cell expanded polyethylene sheath, of suitable thickness, finished with an extruded external film, made up of white, embossed PE-LD, which gives the product further mechanical protection as well as an aesthetic finish, it is non-toxic, odorless and free from chlorofluorocarbons (CFCs).
TWINpolar FN
The sheath
The insulating sheath produced by ISOCLIMA has obtained the fire reaction class BL-s1,d0 in compliance with the European standard UNI EN 13501-1 as the best fire resistance for expanded insulating materials.
Its main characteristics are: excellent elasticity, flexibility and high resistance to the diffusion of water vapor, which allows avoiding the formation of condensation on the surface of the pipe, when fluids with temperatures lower than room temperature are transferred inside the pipe.
The applications
“TWINpolar FN” di ISOCLIMA trova il suo migliore impiego nel trasporto di gas refrigeranti (impianti split o VRV).
