Shell and Tube Heat Exchanger Design (S&THex). Very easy to use and user friendly.
S&THex is a software tool that is made to demonstrate the chemical design & rating calculations of Shell & Tube Heat Exchangers.Unlike other tools, ensures that the calculations are performed step by step to help in understanding the design calculations.
Please note that the software can only do the basic chemical design & rating calculations of shell and tube heat exchangers and some mechanical design design calculations.

Below is a list of some functions:
1) Step by step design and rating calculations
2) Estimate the Physical properties of 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.
3) Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY)
4) Integrated customised database functions to allow user to add/delete compnents.
5) Fixed tube sheet counts and general tube sizes tables
6) Ability to import properties to Shell/Tube sides form Microsoft Excel
7) Export Results summary to Microsoft Excel
8) Ability to calculate unknown shell or tube side temperatures by iteration method (solving by trial and error) - also calculate unknown exit temperatures in rating mode.
9) Also can select from different correlations to calculate shell or tube heat transfer coefficient
10) Calculate the scale resistance (dirt factor)
11) Shell/Tube side Reynolds & Nusselt numbers
12) Buffle number and spacing
13) Recommended minimun shell thickness, minimum recommended number & diameter of rods.
14) Calculate Shell/Nozzle/Channel/Head/Tubesheet Thickness.
15) Support S.I Units and English (U.S) Units of mesurement.
16) Duty Calculation
17) Overall heat transfer coefficient for both Clean and Fouled conditions
18) Shell/Tube velocities.
19) Number of transfer units, Effectiveness, Thermal capacity ratio
20) Pumping power / Inlet and Exit Nozzles pressure losses / Scale resistance Calculators
21) Save/Load results.
22) Generate/Print a summary of results.
