Coupled pipe, for split systems and heat pumps. Suitable for R407/R410/R32 gas
Pre-insulated coupled copper tube 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, the Presidential Decree. 412/93, Legislative Decree 19 August 2005, n° 192 and Legislative Decree 29 December 2006, n° 311.
The copper pipe complies with UNI EN 12735-1:2020 “round copper pipes for air conditioning and refrigeration systems” and is made up of a CU-DHP alloy, annealed in phosphorus deoxidized rolls, with a minimum copper content of 99.9% and phosphorus content between 0.015% and 0.040%.
Based on the above elements, the product copper pipes “BIPOLAR” they are suitable for the passage of refrigerant gases such as R407/C, R410/A and R 32.
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).
Bipolar
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
BIPOLAR by ISOCLIMA finds its best use in the transport of refrigerant gases (split or VRV systems).
