Pair copper coil is also called twin insulated copper coil. It is used for air conditioner installation. The copper coil inside of insulation is compatible for R410a, R407c, R404a, R507 and R22 refrigerants. The copper coil are produced according to ASTM B280 standard, EN 12735-1 standard, AS 1571 standard. The outer insulation tube is three layered structure and made of cross linked PE foam with closed cells. Insulation tubes are covered with embossed PE film to prevent the foam creasing. Our pair copper coil is with RoHS certificate, CE certificate and produced in ISO 9001 management system.
