Sterlco

In 1916, the company then known as the Sterling Engineering Company was established with a corporate mission of controlling heating temperature systems. Today, we design and manufacture boiler feed and condensate packages, valves, traps, strainers, and pumps for steam and hot water systems.

Partnering with Sterling means more than just getting Sterlco® system components. Today, we offer an extensive line of standard products and have in-house engineering that can design a custom package specific to your application. From sterilization and precise temperature control to comfort heating and power generation, Sterlco® offers a variety of steam control products to keep your system running efficiently.
