Italy's US subsidiary, Zilmet USA opened a high-tech facility in Georgetown County, South Carolina, creating 40–50 jobs and citing major cost savings, automation, proximity to suppliers, and strong local workforce support—including top-notch technical schools—as key reasons for choosing South Carolina. Despite recent job losses from plant closures, Zilmet's expansion marks a strategic, innovative investment with future growth plans.

Zilmet is a world leader in the production of expansion tanks for various applications, including hydronic, well, and solar systems, as well as plate heat exchangers. They also offer lines like the INOX-PRO, entirely made of stainless steel for high hygienic standards and longevity in sanitary hot water systems.
