This software performs thermal design and sizing of helical coil heat exchangers. It calculates all the relevant parameters such as area, heat duty, number of coil turns, and length. Additionally, it can handle unknown temperatures or flow rates, among others.

To make the software even more personalized, users can add their own Nusselt correlation in three formats for use in calculations. This can also be supplemented by the software's various built-in correlations or by entering user values. A key advantage of this software is the ability to calculate unknown Cold or Hot side temperature, including unknown exit temperatures on both sides or any two temperatures on both sides. Other features include unknown flow rate on either hot or cold side, pressure drops for both shell and tube sides (frictional, inlet, outlet, and total), overall heat transfer coefficients, heat transfer coefficients for shell and tube sides, area and heat load (duty) calculations, vessel dimensions and length, and the number of spiral turns for the helical tube and its length.
Furthermore, the software comes equipped with a physical properties estimation feature for over 1450 fluids, with the option to download this separately for trial usage. The physical properties software can also estimate mixture properties, but only for liquids currently. The users can also store their own fluid properties, add/delete fluids, tube geometric sizes, etc. in the user database feature, making it easy to load in any project simulation. Other helpful additions include fouling factors and a plot temperature profile for counter current flow and co-current flow, accurately detecting temperature cross.
Exporting and saving work is a breeze since users can conveniently export results summary in Microsoft Excel Engineering Datasheet format, save/load results, and generate and print a summary of results. Additionally, the software allows for displaying multiple cases in results grid and exporting results summary to an.rtf file format that can be opened in Microsoft Word.
However, despite its many advantages, it is worth noting that the software has its limitations. It can only perform single-phase fluid operations and does not support multi-tube units. But all in all, this software has a variety of features that can be very useful in general engineering operations.
