We are offering insulated copper pair coil. Insulated copper pair coil is used for home and commercial split air conditioner installation. The copper tubes inside of ixpe foam insulation with different wall thickness are compatible for r410a, r407c, r404a, r507 and r22 refrigerants. Specifications: copper tube: outer diameter: from 6.35mm to 22.23mm (from 14" to 78") wall thickness: from 0.56mm to 1.40mm ixpe foam pipe insulation: inside diameter: from 8mm to 25mm (suitable for copper tube from 6.35mm to 22.23mm) thickness: 8mm, 9mm length: pair coil: 3m, 5m, 7.5m, 10m, 15m, 20m, 25m, 30m advantage: 100% pure copper: unlike many other split connection line set brands that are made of aluminum, our line sets are 100% pure copper. Aluminum (cu-al) is cheaper than copper so many brands are starting to produce aluminum line sets to save on cost. However, aluminum cannot be cut or reduced like the industry standard copper lines. And most importantly, aluminum lines will result in a loss of energy efficiency. The thermal conductivity is much greater in copper than aluminum (around 60%), so the short term savings of aluminum line sets will result in higher utility costs in the long term. Copper tube with astm b280 certificate and ce certificate our copper tubes are produced according to astm b280 standard and en 12735-1 standard. More important, our copper tubes are with astm b280 certificate and ce certificate.
