Inner-grooved copper coil tube
Introduction
The product adopts the advanced continuouscastingandrolling technology to be made of. It has high precision, high heat dispersion, high clean, light weight. Its internal surface is 65%-100% bigger than smooth copper tube. Traditional coefficient is 1.8-2.0 time higher than smooth copper tube. It has a better prospect in the energy saving application. It is mainly used in household air conditioner, central air conditioning units, radiator pipe road of refrigerator units.
