In high-temperature heat exchangers, failures are rarely caused by material limits alone. Hot spots, non-uniform tube wall temperatures, and uneven stress concentrations are far more often the root cause of fatigue, cracking, and premature shutdowns.
Traditional designs attempt to compensate by specifying higher-grade alloys—driving up cost without addressing the underlying issue.

A more effective approach starts with engineering. By prioritizing flow uniformity and temperature symmetry through advanced CFD-driven design, common failure modes can be designed out—reducing stress concentrations, minimizing pressure drop, and improving overall reliability.
The full AirBTU VPRR technical bulletin expands on these concepts with detailed CFD analysis and engineering data focused on uniformity, stress reduction, and lifecycle performance.
