Traditional Overlapping U-Tube Heat Exchanger

Traditional shell-and-tube heat exchangers, commonly used for phase-change high-temperature heat transfer, suffer from low thermal efficiency, dead zones, difficulty in scaling up, large footprint, and high operational costs—issues that are increasingly becoming critical challenges for major chemical plants. In contrast, coiled tube heat exchangers boast excellent low-temperature performance, a sleek and compact design, exceptional sensitivity, superior sealing capabilities, and even feature self-tightening and self-contracting functions. These advanced units are perfectly suited for efficient heat exchange processes involving large temperature differences and multiple fluid streams. They excel particularly in applications such as superheated steam, saturated steam, multiphase flows, and low-temperature gas-phase heat transfer. As a result, they can be effectively deployed in superheated steam systems and boiler applications, significantly reducing the number of heat exchangers required—and ultimately cutting both capital investment and ongoing operating expenses.
