- Shell & tube heat exchangers are the most versatile type of heat exchangers, and are used in process industries,
- Shell and tube heat exchangers provide relatively large ratios of heat transfer area to volume and can be easily cleaned.
- Shell & tube type heat exchangers are built of tubes, mounted in shells (cylindrical, rectangular or arbitrary shape)
- variations of this basic types are available. The differences lie mainly in the detailed features of construction and provisions for differential thermal expansion between the tubes and the shell.
