Our Mission: Engineering Excellence Since 1998

Island City Engineering was founded with a singular focus: to deliver innovative and robust mechanical solutions to clients in demanding commercial and defense sectors. Based in Merrill, Wisconsin, we have evolved from a specialized engineering firm into a premier manufacturer of proprietary thermal systems and critical vehicle components. Our commitment to in-house design, rigorous testing, and complete client support ensures every product and service we offer meets the highest standards of reliability and performance.

We partner with fleet managers, government contractors, and R&D teams to solve complex problems, specializing in high-mobility vehicle technology and next-generation thermal energy applications, including our flagship Dynamic Heat Generator (DHG).
