inner grooved tube

Item: Inner Grooved Copper Tube

Trait: Even and compact structure , the highly precise dimension , the normative and integrity groove shape , the low interior surface residuum etc., the inside surface area increases 65∼100% than that of the same specification of plain copper tube, the heat transfer coefficient is about 1.8∼2.0 times of that of same specification of plain tube. The products follow the major trend of air conditioners development which is high-efficient, environmental-friendly and more healthy.

Application: It is used for Air Conditioners, Combination Type Air Conditioning Units, Central Air Conditioning, Display cabinet, and so on.

Alloy: according to customers request

Temper: according to customers request

Packing: Coils will have to be collected into a pile to build round 2+2 or 6 coils carried on one fumigated wooden pallet, Cardboard flange to be inserted between each coil. Shrinking film wrapping the parcel. Each parcel composed of 2+2 or 6 coils, will have to be characterized by a label with detailed information about products. The packing also can be done according to customers request.
