GEA is a well-known global engineering company that specializes in various industrial technologies, including heat exchangers.

- **Shell:** The shell provides a protective casing for the tube bundle and facilitates the flow of the service fluid. The shell may have inlet and outlet connections for both fluids.

- **Tube Bundle:** The tube bundle is composed of a series of tubes through which the process fluid flows. The tubes are often arranged in a pattern to optimize heat transfer efficiency.

- **Baffles:** Baffles or dividers are often placed inside the shell to guide the flow of the service fluid and enhance heat transfer by creating turbulence.

- **End Caps:** End caps seal the ends of the tube bundle within the shell and help direct fluid flow.
