The Williams & Davis 2000D fortifies our everlasting reputation for building the most rugged and serviceable scotch marine boiler in the industry. The 2000D further offers a high efficiency design built to maximize flue gas velocities and transfer as much heat energy as possible to the process water instead of exhausting it through the stack or radiating heat into the boiler room. Through stringent and methodical building practices perfected over almost 90 years in the industry, Williams & Davis guarantees each of their boilers will meet, and typically exceed, every ASME standard. All units are operationally tested and shipped as an integrated package when practical, ready for quick connection to utilities. As such, they demonstrate their confidence in their boilers by offering the industry’s best pressure vessel warranty of 10 years (25 year available) with an approved water testing and treatment program.
