Copper tubes coupled and pre-insulated with an anti-condensate sheath in physical cross-linked expanded PE specific for Split-System installations
Characteristics Copper tube
Seamless annealed Cu-DHP 99.90 min. ACR copper (R220) for refrigerant gases. Mechanical characteristics, dimensions, tolerances and eccentricity in compliance with EN 12735-1. It can be used with the new generation refrigerant gases R-407C, R-410A and R-32. Internal cleaning and dehumidification with an inert gas, carbon residue <0,34 mg/dm2 and sealed ends as per ASTM B280.

Coating characteristics
Insulating sheath in physical closed-cell cross-linked polyethylene foam with the following technical values:
• Thermal conductivity at 40°C ≤ 0,040 W/m*K
• Water vapor diffusion resistance factor (anti-condensation) ≥ 15000
• Fire resistance Class 1
• Operating temperature -80°/+120°C
• does not contain CFC
Double external film in white extruded polyethylene (LDPE), with added flame retardant and adhering to the foam to ensure a high degree of anti-condensation, very high resistance to abrasion and scratch.

Fields of application
Specific for all air conditioning, refrigeration and heat pump systems using R407C , R410A and R32 refrigerant gases. The coupling of the pipes allows a significant reduction in installation times and the double coating ensures greater resistance to tears and external agents and facilitates the separation of the pipes during connection.

Delivery and packaging
To safeguard the mirror shine brightness and perfect cleanliness of the inner part, each coil is sealed with a mechanic system. The protective sleeve is ink-jet marked with the brand, dimensional characteristics and progressive size. 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.
