Marine Cooling Performance & Maintenance Decision Support
Marine Heat Exchanger Fouling, Cooling Capacity & Cleaning ROI Tool
Model fouling resistance, heat-transfer loss, cooling-duty margin, outlet temperatures, pressure-drop energy penalty and cleaning economics. Compare current, clean and post-clean performance, identify the thermal bottleneck and estimate when cleaning becomes financially justified.
Heat Exchanger & Thermal Design
The model uses an effectiveness-NTU calculation for sensible heat transfer. Enter clean overall U and the current hot-side and cold-side fouling resistance rather than relying on generic service assumptions.

Advanced mode ranks multiple exchangers by thermal deficit and cleaning economics. Capacity rates are entered directly in kW/K, making the table usable for water, oil, glycol, air or other sensible-heat services without forcing one fluid model.

Engineering screen: The effectiveness-NTU model assumes sensible heat transfer with stable flow rates and fluid properties. It does not replace OEM thermal-rating software, verified fouling measurements, tube-side pressure-drop calculations, two-phase condenser models, seawater chemistry review, vibration analysis, corrosion assessment or class-approved engineering.
