A CHEMCAD user added module (UAM) is a user-defined unit operation, K-value method, or enthalpy method created by the user or a third party.

Benefits of user-defined UnitOps

For example, CHEMCAD users have created UAMs for membrane separators, fuel cells and other proprietary technology.

UAM’s also give users the ability to create new thermodynamic routines, or communicate data with other programs.UAM’s have access to a large number of internal CHEMCAD routines.

Have you implemented your own UAMs already? Add-on Manager administers your UAMs side-by-side with ours from this page.

We implement UnitOps and Thermodynamic Models for you

“In order to program UAM’s you must first be proficient in C++ programming language.” says Chemstations, Inc.’s documentation. Most CHEMCAD end-users cannot spend the time to program complex applications.

We have developed an efficient way to implement UnitOps or thermodynamic models from the mathematical equations. No programming required!

This page shows some of the UnitOps, for which we have the mathematical equations ready for implementation.

Select your UnitOps or the RefProp-Connector for CHEMCAD!

You engineer processes with CHEMCAD. With one of the Unit Ops provided here, you can enhance CHEMCAD with specific functionality.

Some of the UnitOps on this page have a red ribbon “Coming soon”. We can implement them at short notice, if there is a demand. Fill in the form on the bottom of the page to let us know!
