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.

IXPE foam insulation tube, with UV resistant and anti-aging certificate
Thick three-layer irradiation cross-linked polyethylene foam insulation tubes maximize energy efficiency by minimizing energy transfer. The outer layer is UV resistant and anti-aging film. The middle layer is irradiation cross-linked polyethylene foam (IXPE foam). And the inner layer is polyethylene foam (PE foam). Our IXPE insulation foam tubes are with UV resistant and anti-aging certificate.

IXPE foam insulation pipe conform to UL 94 standard, with the UL 94 certificate
