Its ability to handle high pressures, extreme temperatures, and corrosive fluids makes it indispensable across multiple sectors. This article provides an in-depth analysis of shell and tube heat exchangers, including their working principles, design variations, key applications, and maintenance best practices.

The separation of fluids prevents mixing while maximizing thermal exchange efficiency.
