Shell & tube heat exchangers are essential in various industrial processes, including chemical processing, power generation, and oil and gas. These exchangers consist of a tube bundle enclosed in a cylindrical shell, allowing efficient heat transfer between two fluids. Their robust design handles high-pressure applications and a wide temperature range, ensuring durability and reliability in harsh conditions. The modular design facilitates easy maintenance and cleaning, making them versatile and long-lasting solutions for efficient heat transfer in multiple industries.
