Copper Nickel Fin Tube for Heat Exchanger, Condenser, Evaporator
We are one of manufacturers of integrally finned tubes
This integral finned tubes are widely used as heat exchanger tubes because of their large external surface area and high heat transfer performance compared with a plain tube.
This enhanced surface fin tubes allow our customers to either reduce the size of the heat exchanger or increase its performance.
The low finned tubes we manufacture are designed to meet the most efficient and durable thermal performance for the most challenging situations and long lasting service life.

Low Fin tube
The Maximum heat transfer ratio of low finned tubes will be up 2.5 to 3 times to compare with plain bare tubes and also it can be not only reduced the cost for new equipment or retrofitting of old equipments but also save the size or weight of new equipment from the beginning stage of basic design.
