Antunes has been headquartered in the Chicago area since our company was first created in 1955. Our founder, August Antunes, started as a manufacturer's representative, but his passion for making his customers successful led him to manufacture his own products, including pressure switches and foodservice equipment. As our company grew, so did our needs. We started out with just one location but quickly expanded into five separate buildings. In 1999, we moved into a new facility in Carol Stream, Illinois, with enough space for all of our product divisions as well as future expansion.

Antunes established its offices and manufacturing facility in Suzhou, China in 2003. The Suzhou facility brings countertop foodservice and water filtration solutions to customers throughout Asia and the world.

Antunes partnered with NADI Technologies Pvt. Ltd. in 2019 in a joint venture to manufacture and distribute ultrafiltration systems throughout India. Antunes-NADI Manufacturing Pvt. Ltd. is based out of Chennai, India.
