The company's replacement tube bundles for heat exchanger equipment can be constructed for liquid-to-liquid or steam-to-liquid applications. The bundles can be used for applications including industrial processes and commercial water heating or cooling. The tube bundles are built from 10- or 20-gauge copper or cupronickel tubes, carbon steel, or brass tube sheets. The tube bundles are available with a lead time of about 10 working days. A company representative can measure the bundles at the site or can cross-reference them if the OEM's model number is known.
