1. the selection of high-quality copper pipe,aluminum fin production,high heat transfer coefficient. The shell is treated by oil removal, phosphating,purification.spraying and baking, and has èxcellent anti-corroslon performance.

2.the product structure design is reasonable. the support end plate are strengthened,durable easy to install.

3,copper pipe adopts automatic processing and forming process to ensure that the inside of the pipeis dry and dust-free.The aluminum sheet is closely expanded with the copper tube, and the heat transfer effect is good.

4.circuit design to avoid pressure loss as much as possible.The multi-loop cross arrangement makes the heat dissipation effect bettel

5, coil by 2.6mpa air tightness test to ensure product air tightnessrequirements.
