20mm insulation tube is 2 times thicker than normal 10mm insulation, and much better on the thermal protection.Insulation is 3 layers close cell cross-linked 30 times PE foam. Inner layer
is 120˚C resistant seamless extrusion tube. It has better anti condensation charactor due to smaller distance between insulation and copper tube. Outside embossed anti UV film could protect
surface from scratching, deforming and aging so as to ensure its life time to over 8 years.Tube is 20 meters or 30 meters long. Copper tube is soft annealed treated.
