N-ST

Shell and Tube exchangers remain the industry standard for good reason — proven over a century of use, robust in operation, and adaptable to nearly any process duty, fluid, pressure, or temperature range you'll encounter.

N-ST software handles the full sizing and rating calculation: tube count and layout, baffle spacing and cut, shell-side and tube-side pressure drop, and configuration checks against TEMA standard classes so the design you produce is one a fabricator will actually recognize and quote correctly.

The edge: shell and tube design has decades of established correlations behind it, and our tool applies them with genuine rigor rather than a simplified approximation — so results hold up against both engineering theory and long-established industry practice, which matters when the design goes in front of a client's own review engineer.

Output includes a full TEMA-format datasheet, ready to issue for fabrication quotes — tube layout drawing data, baffle configuration, nozzle sizing, and a complete thermal and mechanical performance summary in the format fabricators expect to receive.
