Heat Exchanger Calculator
Size heat exchangers using LMTD method for water-to-water applications.
Typical U-Values
| Type | Application | U (BTU/hr-ft2-F) |
|---|---|---|
| Plate | Water-Water | 150-300 |
| Plate | Glycol-Water | 100-200 |
| Shell | Water-Water | 100-250 |
| Shell | Steam-Water | 200-500 |
Design Guidelines
Min Approach: 5-10F for plate, 10-15F for shell
Plate Advantages: Compact, high U-value, easy cleaning
Shell Advantages: Higher pressure/temp, lower cost for large
Velocity: 3-6 ft/s water in tubes typical
