Superior Boiler received patents for two products that improve hot water heating in the company’s watertube boilers.

The company’s high temperature fluid generator, protected by U.S. patent number 11,047,596, provides greater flexibility on the temperature differential of heating, enabling a swing of 160°F to 450°F. Because of its ability to scale, the fluid generator is designed for industrial applications with large heating loads.

Invented by Sundeep Bodapati, Superior’s vice president of engineering watertube division, the generator’s membrane-style construction uses a simplified design that makes it easier and less expensive to fabricate, says the company. Its components can be built separately and assembled quickly.

Patent number 11,060,717 protects Superior’s multiple-pass flexible watertube boiler and its method of use. Invented by Bodapati and retired former employee John R. English, it allows a 75°F heating differential and uses a tangent-tube construction for low load, smaller building applications. Its design, using a reduced number of tubes and bends, decreases its cost and time to build. Placement of the product’s headers all on one side eases access to the unit.

Superior also holds a steam application patent, issued in July 2020, for its watertube boilers.
