Pressure Drop and Energy Savings

Lower Pressure Loss

Plate and frame heat exchangers from Shanghai Heat Transfer use an optimized plate design to minimize pressure drop. The corrugated plates create narrow channels that guide fluids efficiently. This design reduces resistance, so fluids move smoothly through the exchanger. In contrast, a shell and tube heat exchanger often has a higher pressure drop because fluids must travel longer paths and navigate around tube bundles. Lower pressure drop means pumps use less energy, which leads to cost savings and less wear on equipment.

Facilities notice that a lower pressure drop helps maintain steady flow rates and reduces the risk of system stress. This benefit is especially important in large-scale operations where energy use adds up quickly.

Improved Energy Efficiency
