Heat Exchanger Suite (HExS) bundles various heat exchanger software products under one license. It includes designs for shell and tube, condensers, helical coils, double pipes, thermosiphons, gasketed plates, air-cooled exchangers, and kettle reboilers.


S&THex is user-friendly software for shell and tube heat exchanger design. It provides step-by-step chemical design and rating calculations, enhancing understanding.


PHex is user-friendly software for Gasketed Plate Heat Exchanger design. It performs thermal analysis and basic calculations. You can enter plate dimensions, materials, and calculate unknown temperatures.


DHex is user-friendly software for Double Pipe (hairpin) Heat Exchanger design. It performs thermal calculations and generates a summary of results.


CnD software demonstrates thermal analysis and design calculations for shell and tube condensers. It covers horizontal and vertical configurations, including reflux condensers. Intended for professionals and academics with basic knowledge of thermodynamics and heat exchangers.


Kettle Reboiler Design software demonstrates thermal calculations and analysis for Kettle-type reboilers. It’s user-friendly and provides preliminary sizing calculations.


The Air Cooled Heat Exchanger Design Software (ACHex) performs thermal calculations for air-cooled heat exchangers, allowing users to design and size units for liquid and gas services, with a three-page summary of results and basic drawing representation.

PEngCalc, a process engineering calculator, bundles 29 common calculators into one software. It offers a productive environment for users, performing calculations and generating summarized reports that can be copied for external use.


The Orifice Design Calculator sizes gas/liquid orifice plates according to ISO5167 (2003) and Crane’s Flow of Fluids through Valves equation 3.22. It calculates mass flow rates for specific orifice sizes, generates profile charts, and produces an Excel-based engineering data sheet or a printable summary.


The Physical Properties Estimation Database is a software product that estimates physical properties using pure properties and equations. It’s included free with any heat exchanger software purchase, but you can also buy it separately. With over 1400 components, it calculates physical properties based on correlations—all you need to provide is the temperature!


The Relief Valve Sizing Calculator performs calculations based on equations specified by the American Petroleum Institute. These equations help engineers size relief devices suitable for various industrial applications.

PhysPro Fluid Properties estimates fluid properties using two powerful databases, covering over 400 fluids (including 55 common refrigerants). It calculates constant and mixture properties, including humid air properties. You can generate saturation tables, plot charts, and copy data for external use.

The Decanter Sizing Calculator (DSC) is specialized software for sizing horizontal and vertical decanters. It handles multiple cases, accepts input in various units, and customizes output display. Users can export or print the results to their preference


The Heat Duty Calculator is free software that computes sensible heat duty and latent heat transfer rates.


The Sonic Velocity Calculator, also known as the Gas Sonic Velocity calculator, determines the maximum velocity a gas can reach in a pipe or through an orifice. It’s crucial for design and safety considerations

The Pumping Power Calculator is a versatile tool that calculates fluid pumping power. It accepts input in both SI and Metric unitss


This is a very simple calculation in engineering! In fact, I made this software tool for fun. It’s easy to use.


To calculate the log mean temperature difference (LMTD) for counter-current and co-current flow.
