New disc technology boosts
centrifuge separation capacity
UniDisc (photo) is this company's latest
innovation for disc stack separators.
This new disc technology is said
to increase separation capacity by as
much as 30%, while simultaneously
providing an extremely high degree
of hygiene. Unlike traditional separator
discs with caulks that have been
welded to the plates, discs with UniDisc
technology feature micro-caulks
that are formed during the pressing
process. This ensures even, minimal
spacing between the discs in the disc
stack. By reducing the amount of spacing
between each disc, it is possible
to fit more discs within the same volume.
Increasing the number of discs,
in turn, means increased separation
area with an improved flow capacity.
The micro-caulks are integrated into
the design of the disc itself. The multitude
of small caulks strengthens the
disc construction while simultaneously
ensuring greater hygienic properties
than possible in previous generations
of disc stack technology. - Alfa Laval

High-pressure rupture discs now
have extended service life
Since this company's engineers have
modified the standard rupture-disc
design, its high-pressure rupture discs
(photo) have become significantly
more durable. The welding seam of
the rupture disc is not stressed as
usual, in terms of shearing and bending,
but only in terms of pressure.
Through the geometric separation of
the stress spike and the welding seam,
the rupture disc is longer-lasting and
allows the lowest rupture tolerances of
up to ±3% at pressures of up to 5,000
bars and temperatures up to 400°C.

This compressor is more
compact than its predecessors
The new Aerzen Turbo G5plus (photo)
high-efficiency turbocompressor features
air-foil bearings with a double
coating of Teflon and graphite, which
provides increased temperature resistance
and a lifetime of more than

80,000 h of operation - independently
from start and stop cycles. A
new multilevel frequency converter
technology (>55 kW) reduces the heat
loss in the motor to a minimum and,
consequently, improves the total efficiency
significantly. Turbo G5plus is
offered for volume flows from 300 to
8,400 m3/h, and for a maximum pressure
of 1,000 bars. Eight blower sizes
from the small AT 25-0.8 G5plus to the
largest model AT 200-1.0 G5plus are
currently available, and five more are in
preparation. - Aerzener Maschinenfabrik

A tablet that enables
augmented reality applications
The newest product in the Tab-Ex
series of hazardous-area mobile devices
(photo) is based on the latest
Samsung Galaxy Tab Active2 and integrates
augmented reality (AR) applications.
With the Tab-Ex 02, users
can communicate in realtime, as well
as collect and retrieve data, parameters
and information remotely. Due
to its magnetic gyroscope, the tablet
enables users to identify objects in an
installation via AR applications. The
software delivers all underlying, existing
data directly on the mobile device's
display in realtime, while also making it
shareable within a company's network.
Whether through construction plans,
maintenance information or operating
states, the reality is enriched and extended
by virtual data already stored
in the plant. The mobile use of AR can
solve multiple challenges and tasks in
the industry, from rapid commissioning
of a plant, transparent processes and
precise maintenance to efficient asset
management. - ecom instruments
