Coil Wound Heat Exchanger (CWHEs)

Coil wound heat exchanger design (CWHEs), also known as Giaque–Hampson Heat exchangers, spiral tube heat exchangers, or coiled tubular heat exchangers, are commonly used in natural gas liquefaction processes.

The coil wound heat exchanger design entails winding many small diameter tubes in a helical geometry around a central core tube, or mandrel. The tubes are arranged in multiple layers within a cylindrical shell. The arrangement is quite flexible, allowing multiple streams to be accommodated in a single heat exchanger in more complex configurations. CWHEs are used in multiple industries including the cryogenic industry, for the production of Liquefied natural gas (LNG), Liquid Nitrogen, Liquid Oxygen, and Liquid Argon.

Advantages of Coil Wound Heat Exchanger

• Coil wound heat exchanger requiring low power.
• Coil wound heat exchanger can withstand high pressure
