The Williams & Davis Series 2000D is a classic 2-pass, dry-back horizontal firetube boiler that offers high efficiency, flexibility, reliability, safety and ease of operation. The Dryback design provides full access to boiler tubes, tube sheet, and furnace for ease of maintenance and includes single rear tube sheet construction, which reduces tube sheet stresses. Series 2000D provides high flue gas velocities and low stack temperatures to maximize its performance. All units are factory fire tested and shipped as an integrated package, ready for quick connection to utilities.

3. 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 our
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, we demonstrate our
confidence in our boilers by offering the
industry's best pressure vessel warranty of
10 years (25 year available) with an
approved water testing and treatment
program.
