Copper Pair Coil with Insulation Coat and Brass Nut
The Copper Pair Coil with an insulation coat can be used in all plants for air conditioning and refrigeration and it is suitable for the use of refrigerating gas consistent with copper like R407 and R410A.
The in-line production control by a defector and the continuous control of the external diameter and wall thickness guarantee the maximum safety of the copper tubes. The tubes are supplied clean, internally decreased and capped. Copper Pair Coil with insulation coat and brass nut
