Below are all the update history for shell and tube heat exchanger design software

S&THex v3.4.0.0

+ Upgrade multi case feature to allow cases to be reloaded from a case list window

S&THex v3.3.0.4 

+ Update to Nusselt user number correlations, user can designate correlation side “Shell”, “Tube” or “Both”
+ Correlation added by user will now show up in correlation selection screens per designation above
+ Enhance Chart plot feature
+ Added temperature profile plot to generate a chart window
+ Added temperature cross warning (Design Mode) – if software detects a temperature cross, it will warn the user at Step 4
+ Software will also show a chart window for user to plot the temperature profile for the detected warning above.

S&THex v3.3.0.3 

+ New fouling factors tables
+ Minor correction to Nusselt user correlations screen, deleting a row will now clear the Correlation Label text.

S&THex v3.3.0.0

+ Added calculation for Required Overall heat transfer coefficient (Design Mode)
+ Added Thermal design advisory notes (Design Mode)
+ Overall heat transfer coefficients data table update
+ Compare unlimited cases in data grid table
