SEC Shell and Tube Heat Exchangers

The Shell and Tube (u-tube) is the most common type of heat exchanger used in the process, petroleum, chemical and HVAC industries, it contains a number of parallel utubes inside a shell. Shell Tube heat exchangers are used when a process requires large amounts of fluid to be heated or cooled. Due to their design, shell tube heat exchangers offer a large heat transfer area and provide high heat transfer efficiency.

There are many different types or designs of shell and tube heat exchangers to meet various process requirements. Shell and Tube heat exchangers can provide steady heat transfer by utilizing multiple passes of one or both fluids. SEC shell and tube heat exchangers come in two (2) and four (4) pass models standard, and multi-pass custom heat exchanger models.

Shell and Tube heat exchangers use baffles on the shell-side fluid to accomplished mixing or turbulence. Without the use of baffles, the fluid can become stagnant in certain parts of the shell.
