Committed to Water since 1991

Swan was founded on January 1st, 1991 by a group of experienced engineers (chemists, physicist, electronic engineers). It has been concentrating its efforts on the development and manufacturing of process analytical instruments for monitoring the water quality.

In the beginning, only 10 people worked for Swan, including the founders. They first focused on swimming pool and sanitary water applications as well as waste water treatment. Very soon Swan set the standard for the control of many other water quality parameters.

In fact, the company expanded their activities to the power generation market (Water-Steam-Cycle monitoring) and semiconductor industries. With entry into the power market, the rapid growth of Swan started.

Other milestones in Swan’s success story included the foundation of a separate Swan Systems department in 1997, which supplies water steam cycle knowledge and sampling & analysis systems (SWAS). 

Today, more than 120 people work for Swan in Switzerland, and approximately 300 people worldwide. Even the founders, part of the Director’s Board, are still active in the research and development department of Swan.
