Copper tube pre-insulated in extruded polyethylene foam, seamless, protective anti-UV film, Class 1, for air conditioning installations
Copper tube characteristics Seamless annealed Cu-DHP 99.90 min. A.C.R. copper (R220). Mechanical characteristics, dimensions tolerances and eccentricity in compliance with EN 12735-1. Internal cleaning and dehumidification with an inert gas, carbon residue < 0.34 mg/dm2 and sealed ends as per ASTM B280. Coating Characteristic Insulating material made in extruded polyethylene foam seamless, with closed cells and very high resistance factor to the diffusion of water vapor (anti-condensation ≥ 15000) and fire resistance Class 1. The expansion of the coating is carried out without the use of CFCs and HCFCs which are harmful to health and to environment as per European Regulation EEC/EU 2037/2000. • Thermal conductivity at 40°C ≤ 0.40 W/m*K • Operating temperature -40°/+105°C In order to avoid the crystallization process of the PE exposed to the action of sunlight, in the outdoor installations the insulating sheath is protected by LDPE film of grey aluminium color able to absorb UV radiation keeping unchanged the coating characteristics. The anti-UV additive is environ friendly, halogen free, it is present in the LDPE film and it does not counteract with the flame retardant. Fields of application Specific for all air conditioning and refrigerant gas transportation R407C, R410A e R32. It is suitable for areas with high annual solar radiation. Delivery and packaging The copper tube is marketed in coils and the copper diameter is expressed in inches as required by standard EN 12735-1. To safeguard the mirror shine brightness and perfect cleanliness of the inner part, each coil is sealed with plastic caps at the ends. The protective sleeve is ink-jet marked with the brand, dimensional characteristics, the self-extinguishing class and the progressive size meter. Packaged in coils with PE film on wooden pallets with cardboard layer and firmly anchored by an extensible film in transparent polyethylene that completely wraps it up. Customizations We can customize the marking of the LDPE external film.
