1. 13.5 Low Aluminum Finned TubeThe low aluminum finned tube is suitable for the small sized heater. It is made of aluminum, so it has good cost performance rate. Now it has been applied by the Zhejiang Sanli Purify Equipment Co., Ltd. on their products.
    1. 17.5 Low Aluminum Finned TubeThe 17.5 low aluminum finned tube is designed for the heat exchanger within small space. We adopt the aluminum material to greatly lower the production cost and price, without sacrificing the heat exchange efficiency. Now, this product has been praised by the Zhejiang Sanli Purify Equipment

Low Finned Tubes

The low finned tube is made from the seamless metal pipes by means of extrusion process. The outer diameter usually exceeds pipe end diameter.

Applications
Our low finned tube is widely used in the manufacture of air conditioning equipment, like the refrigerant condenser and refrigerant evaporator, the machinery, like oil or gas cooler, the electricity power generation equipment and process equipment.

Materials
Copper and copper alloy
10# Carbon steel pipe
Stainless steel pipe (fin height ranges from 0.8mm to 1.3mm)
