line offers dry-screw vacuum-pump
designs with fixed- or variable-pitch
screw rotors. The pumps achieve an
ultimate vacuum of .0015 in. Hg, and
can operate at any pressure between
end vacuum and atmospheric pressure.
The pumps' design offers high
vapor and liquid tolerances and can
handle corrosives, organics, inorganics
and solvents because of its oilfree,
non-contacting screw design.
In this design, the shafts and screws
are one solid piece, which eliminates
corrosion between the screw rotor
and shaft that can occur in other
pump designs, says the company. A
low rotational speed avoids noise and
vibration. - Gardner Denver Nash,

Monitor reformer-tube
temperatures in realtime
trol room. During startup, burners
that are not operating correctly can
be quickly identified and the effect
of impinging flames can be seen,
helping to optimize performance and
reduce downtime. - Ametek Land,

The near-infrared borescope NIR-B
3XR (photo) delivers continuous,
high-accuracy reformer-tube-wall
temperature (TWT) measurement,
furnace optimization and monitoring,
giving operators the ability to measure
temperature point data and to
store this data for future analysis.
Operating with a wide-angle field of
view (90 deg) and a high-resolution
image, the NIR-B 3XR allows multiple
reformer tubes to be imaged and
measured simultaneously. That capability
is critical to extending asset
life and maximizing efficiency, as a
-10°C measurement error over time
can result in either 1% lost productivity,
while a +10°C error can result
in a 25% reduction in tube life. The
NIR-B 3XR's advanced digital-communications
capabilities mean that
both image and data can be viewed
in realtime from the safety of the conOrbitor
Eco fast-cycle impingement
cleaners (photo) are an alternative
to spray balls for cleaning tanks and
storage vessels. Rather than being
geared for maximum power, Orbitor
Eco devices are instead configured
for maximum speed and water efficiency.
These new machines can
complete a cleaning cycle in under
two minutes with flowrates as low
as 45 L/min. When compared with
spray balls, Orbitor Eco products
operate at a similar pressure (2-3
bars), while offering a larger cleaning
range (up to 10-m diameter), as
much as 95% reduction in water
consumption per cycle and a shorter
cleaning-cycle time. With the availability
of universal fittings, connectors,
a range of threads and where
required, adaptors, it is likely that in
many cases, existing tanks, pumps
and pipework will not need to be
changed significantly for cleaning
with Orbitor Eco devices. - Bete
