State-of-the-Art Equipment and Extra
Safety Precautions Help nexAir Keep
Atop Cylinder Filling Trends
By Troy Goode
While traditional cylinder delivery remains a large portion of our business,
we’ve seen a lot of customers buying into
microbulk and even bulk gas systems for
lower costs, an uninterrupted supply of
product and on-site customer inventory
management via telemetry. We’ve also
realized the extraordinary benefits of utilizing bulk gas systems for filling cylinder
gases for delivery, and recently installed a
Chart Siphon 100™ Bulk Storage Tank at
our cylinder filling plant in Memphis. This
is just one of the ways we’ve expanded our
capabilities to ensure ease of use for our
customers while also staying atop the industry’s most recent trends.
Newest Argon Bulk Tank
Saves Time and Money
At nexAir, we are constantly looking for
new methods, equipment, or technologies
to improve our efficiency, decrease costs
and increase product utilization. Qualitative measurement of product losses is essential for reducing gas costs, and we’ve
been able to save costs by keeping good
production records and effectively controlling our inventory. nexAir invested in
the Siphon 100 tank mainly to decrease
product losses and save on maintenance
costs.
Used primarily for filling high-pressure
cylinders, liquid cylinders, and transports,
the Siphon 100 tank is unique in that it
allows us to utilize close to 100 percent
of the tank’s contents. By integrating
two technologies — a thermal-siphoning
system within the tank itself and Chart’s
multi-layer Composite Super Insulation™
— we can effectively reduce heat from the
inside and outside of the tank. The thermal-siphoning technology repurposes the
heat from pumping and keeps the pressure
in the vessel low (between 75 and 100
pounds per square inch gauge). The super
insulation is roughly 30-70 percent more
effective in reducing the heat transfer from

the outside atmosphere. Reduced heat
from within and outside the tank improves
our liquid quality and results in increased
high-pressure pumping capacity, faster
pump cool down, and better gas utilization. We now only see two to five percent
product losses per month as opposed to
the 10-13 percent we were seeing before
— resulting in roughly $4,000 in savings
per month.
The Siphon 100 tank also has a complete
vacuum-jacketed piping system from
tanker delivery to pump, and pump cavitation is reduced by using a vacuum-insulated pod that provides colder liquid to
the pump. Extended tank legs add head
pressure to the pump without increasing
liquid inventory, which also results in
improved pump performance. The tank’s
lower pressure liquid also increases the
life of high-wear parts. Increased pump
life results in savings in maintenance time

very valuable to us as we consistently try
to ensure that our customers receive orders
on time.
Acetylene Plant
Improvements for Safety
Also, in response to the Compressed Gas
Association and the National Fire Protection Association requirement that all
mobile acetylene trailers (MATs) be under
a sprinkler system, nexAir recently completed a project to enhance its acetylene
trailer storage and safety at our Memphis
plant. We installed concrete fire walls
between the acetylene trailers, a rear
concrete fire wall, new overhead piping
from the trailers to the acetylene cylinder
charging plant, and a new water sprinkler
system. These upgrades will help ensure
our mobile acetylene trailers and the associated storage areas are up to code and
also serve as extra safety precautions for
the entire plant.
At nexAir, we’re constantly trying to
provide our customers with the best products for their needs, all while maintaining
safety at our facilities. The Siphon tank
not only offers industry-leading bulk gas
delivery, but is also a more efficient method of delivering Argon. Exercising caution at our acetylene plant is just one of
the ways we’ve improved our processes
to offer the highest level of safety for our
employees and customers.
