Gasketed Plate Heat Exchanger Design (PHex) is a software tool that is made to demonstrate the clean scanthermal analysis and calculations of Gasketed Plate Heat Exchangers.

The calculations are performed through a series of click buttons arranged in order.
Please note that the software can only do the basic design calculations the mechanical design!.
The software is easy to use and have the ability to calculate unknown temperatures
The plate dimensions and materials can be entered, this includes the size of plate heat exchanger and chevron angle.

Main features:

1. Support S.I Units and English (U.S) Units of measurement
2. Unit converter containing 23 measurements with 200-unit conversion.
3. Full version includes manufacturers plate database containing over 230 plates.
4. Import physical properties data to hot side and cold side from Microsoft Excel & from WeBBusterZ Physical properties database (included!)
5. Save/Load results
6. Export Results to Engineering Data sheet format (Microsoft Excel or pdf)
7. Export Results summary to Microsoft excel or Print Results summary.
8. Create multi cases and view all in one multi case grid
9. Temperature and Flow rate estimation in the event of insufficient data.
10. Heat load required (clean or fouled) calculations.
11. Total effective area calculation.
12. Surface area calculation.
13. Number of plates calculations.
14. Overall Coefficient (clean / dirty) calculations
15. Pressure drop Channel/Port/Total for Hot side and cold side Calculations.
16. Plate heat exchanger dimension calculations.
17. Velocity through ports, Mass velocity through channel/ports calculations.
18. Reynolds and Nusselt numbers calculations.
19. Select from a list of 12 Nusselt number correlations.
20. Heat transfer coefficient calculations
21. Ability to define a heat load
22. Calculate two unknown temperatures
23. Plot temperature profiles for counter current flow and co-current flow
Included Databases
24. Estimate the Physical properties of pure components for more than 1450 components; the database has the ability to estimate Thermal Conductivity, Density, Heat Capacity and Viscosity. The database also included critical properties, boiling and melting points and come as separate software but easily integrated with the software.
25. Create your own database of Plates and Components. You can add your fluid physical properties and load the data to your project.
26. Add your own Nusselt number correlation in two different formats through correlations database and use them during software calculations
27. Fouling factors
28. Overall heat transfer coefficients
29. Material Thermal Conductivities.
There is the ability to specify a heat load as a required value, this version also includes the ability to calculate any two unknown temperatures providing that the heat load and flow rates are specified
