About Us

Built on the Plant Floor

Cygnet Controls, Inc. is an industrial automation and control engineering firm based in Darien, Illinois — serving demanding process industries for over 25 years.

Who We Are

Cygnet Controls, Inc.

We design, fabricate, and program control systems for some of the most demanding process environments in the country — from petrochemical facilities and municipal water systems to pharmaceutical manufacturing and nuclear power plants.

Every project we take on is approached with the same commitment: engineer it right, build it to last, and stand behind it. Whether you need a single panel or a full system rollout, you get senior-level attention from first concept to final commissioning.

We are also the only company in the industry dedicated to the design and manufacture of custom industrial process simulators — from stock signal simulators to fully custom multi-channel training workstations.

Custom Capable
No two plants are the same. We design to your process, your environment, and your team — not to a catalog.
