The Basco^® hairpin heat exchanger, a special U-shaped product, is equipped with movable combined SCDP split tubes. When compared with other heat exchangers, the heat exchanger in this series saves more space and is more efficient, thus reducing the initial cost and overall weight and meeting the custom cooling requirements. The seal design ensures excellent leakage resistance. The tube bundle can be removed easily, facilitating cleaning and ensuring high adaptability to scenarios with unbalanced shell-side flow or large fluid temperature or pressure difference between the shell and the tube.
