Who We Are
A Full-Service Industrial Manufacturer Built on Precision
American Denco Manufacturing (ADM) is a South Windsor, Connecticut-based manufacturer with over 75 years of experience designing and building fluid handling and control systems for critical industrial applications.
We are a one-stop shop — from initial engineering and detailed drawings through fabrication, assembly, in-house testing, and final documentation. Every system that leaves our facility is built to your exact specification and verified to perform before it ships.
Our work supports power generation turbines, naval vessels, offshore platforms, aerospace test cells, semiconductor fabs, and industrial process machinery worldwide. No two projects are alike, and our engineering team thrives on solving the problems others walk away from.
