1. Fin type: corrugated sheet or flat sheet.
2. The copper tube is made of high-purity seamless copper tube, which has long service life and is not easy to crack and corrode.
3. The outer end plate of the coil tube is made of high-quality steel plate with high strength, corrosion resistance and easy assembly.
4. The unique cross-tube method can ensure uniform distribution of the windward area of ​​the entire coil.
5. The fins and copper tubes are mechanically expanded or super-high pressure hydraulic tubes to ensure tight contact and better heat transfer.
6. The spacing of the sleeves is large, which reduces the influence of the coiling of the low temperature system coils.
7. The internal circuit of the coil is required according to the design flow rate. It adopts single and double reflux systems, with small water resistance and good heat exchange performance.
8. The refrigerant coil is heated by vacuum drying at a high temperature to ensure that there is no impurity in the chamber.
