DX type top-suction single-side outlet air cooler；
DH Series Top-suction Double-side Air-outlet Cooler；
DB Series Aluminum Tube and Aluminum Sheet Cooler：
The coil of this series of air coolers is aluminium tube and aluminium fin. The fin heat exchanger tube adopts expansion joint technology, which has high heat transfer efficiency and strong corrosion resistance.
The heat exchanger tubes are staggered and the air distribution is reasonable.
The fin is a positioning method which combines the deep drawing sleeve with the fixed distance, and the positioning is accurate.
Fins and heat exchanger manifolds are expanded by imported special equipment. The fins are in close contact with each other and have low contact thermal resistance.
Selection of high efficiency, low energy consumption, bottom noise axial fan and imported bearing
