Welcome to WelChem!

As an engineering office, WelChem GmbH provides you with software, consulting and training "around the column".

Our hydraulic column software TrayHeart is the most comprehensive commercial software in this field. Using a variety of calculation for all types of trays, random and structured packings, supports, droplet separators and liquid distributors, you can analyze existing or design new towers.

In addition, we can train you on column design, internals selection, tower inspection and support you in debottling and trouble shooting.
