PRE-INSULATED COPPER PIPE WITH SEAMLESS ELASTOMER SHEATH, WITH HIGH RESISTANCE PROTECTIVE FILM FOR HARSH ENVIRONMENTS. UL94 V0 – EUROCLASS BL S2 D0.
Flexible insulating material in extruded elastomeric foam (FEF) based on synthetic rubber according to EN 14304:2016 without welding, closed cells. The special elastomer insulation guarantees superior antimicrobial protection for greater safety against the formation of mold and fungi.
- Thermal conductivity at 40°C λ ≤ 0,037 W/m*K
- Water vapour diffusion resistance factor (anti-condensation) ≥ 10000 μ (EN ISO 13469:2016)
- Fire reaction: UL94 V0 – Euroclass BL s2 d0 (EN13501-1:2019)
- Operating temperature: -50° ÷ +110°C (-58° ÷ +230°F)
- Does not contain CFCs
KELLY’s black protective film offers the highest mechanical
esistance among all the Products in the range.
ACR copper Cu-DHP (Cu = 99.90% min., P = 0.0015 ÷ 0.040%), annealed in rolls (R220). Dimensions, tolerances, and finishes according to ASTM B280. Internal cleanliness is ensured by sealing the ends of each tube.
Designed for critical applications or particularly harsh environments (industrial, rental, military, field structures) it has a highly resistant cover, specific for all split systems for air conditioning, refrigeration and heat pump systems that use refrigerant gases such as A1, A2L and A3. A1, A2L and A3.
