The Henglong design avoids the need for baffles altogether. The helix-shaped tubes are assembled into a bundle on a triangular pitch, one row at a time, with each tube being turned to align the twists at every plane along the bundle length. In that way, each tube is firmly and repeatedly supported by adjacent tubes, which helps eliminate tube vibration. The completed bundle is then tightly strapped circumferentially to ensure no tube movement, resulting in a strong and robust module. The twist arrangement with gaps aligned between the tubes also provides clear washing lanes on the shell side, making high-pressure water lancing an effective cleaning method.

The company says the twisted-tube design provides a higher heat transfer coefficient than any other type of tubular heat exchanger for three reasons: The complex swirl flow on the shell side induces turbulence; the twisted tubes force a powerful tube-side turbulence; and uniform flow distribution extends the effective length of the bundle, providing more surface area than conventional shell-and-tube heat exchangers. According to some estimates, heat transfer coefficients with the twisted-tube design are 40% higher than those found in a conventional shell-and-tube heat exchanger with a similar pressure reduction.

The twisted-tube design is being used in the power industry for turbine steam condensing, boiler feedwater heating, and lube oil cooling, as well as other applications.
