company could no longer rely on one of the
60 BHP generators to take over if the other
went down.
SUPPLYING STEAM
When Schooner decided to incorporate
Rotogravure printing into their operations
in the 1990s, it launched a search for a safe
and effi cient method to power rotary presses
and dry the ink substrates. Initially, they
were looking at boilers for the job. Yet, aſt er
consulting several suppliers, the message
was clear: they needed a steam generator,
not a steam boiler.
Clayton Industries, City of Industry,
CA (claytonindustries.com), provided
the solution. Schnooner owner Pat Bluett
related, " We chose Clayton steam generators
because they had a reputation for safety,
reliability, and effi ciency. Th e single-coil

design of the generators has enabled a
history of no industrial accidents. Clayton
products are guaranteed to never have a
steam explosion. "
Th e steam generators' contribution to
Schooner's printing quality is ultra-dry
saturated heat. Th e fi xed-vane steam
separator produces 99.5% dry steam or
vapor with a consistent absence of water or
any other form of liquid. Compared with
other available equipment, Schooner found
Clayton to be the driest saturated steam.
Will Brozowski, Clayton senior account
executive said, " Th e Schooner process
entails running numerous custom batches
during a shiſt ; they run two shiſt s a day.
When they leave at the end of the day, they
shut the steam generators down. "
Pat Bluett added, " Every morning we can
start cold and can be ready to work in 10
minutes-signifi cantly more effi cient than a
PROACTIVE REPLACEMENT
Initially, the idea was to replace one of
the 60 BHP steam generators with a new
100 BHP model. As Tim Bluett said, " We
fi gured if the 60 went down, we could run
both presses with the big steam generator. "
Aſt er Schooner obtained the new steam
generator in 2018, it was decided to go the
extra mile and replace the other. Bluett
continued, " Th e original installation was
seamless, and the replacement went even
smoother. With a larger number of orders
coming in each week, we thought, let's be
proactive, let's replace the other steam
generator as well. "
Using a counterfl ow design and controlled-circulation-system
technology,
Clayton steam generators deliver forced and
circulating feed water to the combustion
gases. Th is results in optimum heat transfer,
allowing rapid start-up. In addition, the
steam generator water-treatment chemicals
and coil-guard technology maintain
ultra-dry steam while protecting the
machinery. Th e technology ensures longer
equipment life and less downtime for maintenance
and repairs.
Th e second generator was replaced in
2020 with no problems. Schooner has been
able to meet their daily quota by running
multiple custom batches during each of
their two daily shiſt s. EP
