Coil wound heat exchanger

Coil wound heat exchanger is 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.

The advantages to be high pressure and high temperature resistant, good sealing performance, safety, and reliability of shell and tube heat exchanger.
Especially suitable for large-scale chemical equipment in the fields of oil refining, chemical industry, metallurgy, environmental protection and so on.
Catalytic, reforming, hydrogenation and aromatics units. Likewise, it can also be used in oil refining and chemical plants such as atmospheric and vacuum distillation, ketone benzene, catalysis, gas separation and methanol.

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 heat exchangers can be within 5°C.

The main characteristics it has :

  • Ease of operation and maintenance
  • Efficient heat transfer at high temperatures
  • Low temperature approach, which allows heat to be recovered more efficiently
  • Easy to achieve large-scale (25 000m², maximum area of a single high-efficiency heat exchanger)
