Properties of Copper pipe
ACR annealed (R220) copper; mechanical properties,
dimensions, tolerances and eccentricity in conformity
with standard UNI EN 12735-1. Can be used with
refrigerants R407C and R410A gases, internal cleaning and
dehumidifying with inert gas with max overall residue 0.034
g/sq m and ends sealed as laid down by ASTM B280.
Insulation
Closed-cell physically cross-linked expanded polyethylene
insulating sheath with the following specifications:
• thermal conductivity at 40°C λ ≤ 0.040 W/m*K
• water vapour diffusion resistance
(anti-condensation) factor μ ≥ 15000
• reaction to fire class 1
• operating temperature -80°/+120°C
• CFC free
External protective film (LDPE) in extruded
polyethylene, white colour, with added flme retardant,
adherent to expanded foam in order to guarantee a
high level of anti-condensation, high resistance to
abrasion and tears.
