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:
Software Features-----
+Step by step design and rating calculations
+Support S.I Units and English (U.S) Units of measurement
+Rating and Design Modes
+Save/Load results.

Results:-----
+Export Results to Shell & Tube Engineering Data sheet. You can print the data sheet or export it to pdf format or Microsoft Excel for editing
+Export Results summary to Microsoft Excel, Print Results summary.
Calculations:
+Duty, Shell/Tube velocities,  Unknown shell or tube side temperatures,  also calculate unknown exit temperatures in rating mode
+Number of Baffles and Baffle spacing, Scale resistance (dirt factor)
+Overall heat transfer coefficient for both Clean and Fouled conditions
+Select from different correlations to calculate shell or tube heat transfer coefficient
+Shell/Tube side Reynolds & Nusselt numbers
+Pressure Drops.
+Recommended minimum shell thickness, minimum recommended number & diameter of rods.
+Calculate Shell/Nozzle/Channel/Head/Tube sheet Thickness..
+Number of transfer units, Effectiveness, Thermal capacity ratio
+Pumping power / Inlet and Exit Nozzles pressure losses / Scale resistance Calculators
+Ability to import properties to Shell/Tube sides form Microsoft Excel very useful if you want to import your own physical properties

Included Databases:-----
+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 a standalone interface but easily integrated with the software.
+Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY)
+Ability to add your own properties in the additional user databases.
+Fixed tube sheet counts and standard tube sizes tables
+Fouling factors and Overall heat transfer coefficients included.
