Coil wound heat exchangers

Coil wound heat exchangers are one of the most advanced, efficient and energy-saving heat exchange equipment in the world.


It not only has the advantages of high heat transfer efficiency, compact structure and light weight of plate heat exchanger, but also has the advantages of high pressure and high temperature resistance, good sealing performance, safety and reliability of shell and tube heat exchanger.


Judging from the current situation of global water and energy shortages, this product has broad application in industries with large energy and water consumption.


The coil wound tube heat exchanger is made of one or more groups of spirally wound tubes placed in a shell. The heat exchange tubes has enhanced heat transfer elements such as smooth tubes, corrugated tubes and internal thread external bellows, which are arranged in the shell at different spiral angles.









Compact structure and small foot print. Coil wound tube heat exchangers are usually arranged vertically, and occupy only about one-tenth of the area of ordinary shell and tube heat exchangers.

Easy to achieve large-scale

Limited by tube length and transportation, ordinary shell and tube heat exchangers have a maximum area of 3 000 m², while coil wound tube heat exchangers have a maximum area of 25 000 m² per shell.

Easy to implement a variety of media

Up to 8 different medias can be heated, condensed and cooled simultaneously.

High temperatures and pressures

Due to the specific design of our coil wound tube heat exchangers make them extremely robust, they can handle much larger temperature and pressure differences than other heat exchanger types.

Low temperature difference stress

The heat exchange tube of high-efficiency heat exchanger adopts spiral structure, which is equivalent to setting countless expansion joints in the heat exchanger. The heat exchange tubes can expand freely when subjected to temperature.

Low temperature approach

You can reach a very close temperature approach, which can effectively recover more heat. The spiral winding process of the heat exchange tubes in the shell is long, 4 to 6 times that of the shell side. The temperature difference of ordinary shell and tube heat exchangers is generally about 40°C, while the temperature difference of wound tube heat exchangers can be within 5°C.


The tube side media stays in the heat exchange tube bundle for a longer time, and the condensation is more complete.

High efficiency heat exchanger

Due to the spiral design of the tubes, the fluid has to change direction continuously, thus facilitating turbulent flow. This increases heat transfer efficiency and reduces the heat exchange surface area. Compared with ordinary shell and tube heat exchangers, its heat transfer coefficient can be increased by 6 times.
