1 Raw materials: Copper pipe for R410A with high density& pressure and advanced workmanship;

2 with special designed soldering material & Aided welding for inner space, which have guaranteed disperse pipe with durability and no leakage;

3 Shape dimension has optimized from old ones: total length has been shortened, while thickness inreased, especially for TEE parts which has assured the influency of refrigerant; Besides, the improvement of pipe has greatly inreased cost performance;
