to be monitored with a single system.
It consists of a compact and wellorganized
monitoring and control unit
with LED display. In addition, optional
remote-indicator stations may be
specified for the process environment.
Since the remote indicator stations
are supplied via the intrinsically safe
circuits of the monitoring and control
unit, no additional external power supply
is needed. - Hoerbiger Safety

A new high-pressure
combination air valve
The new high-pressure combination
air valve, the ASU-CAV (photo) is a
single body, combination automatic
air valve featuring an innovative design
for clean or dirty service applications
in mining, petrochemicals, water
treatment, reverse osmosis and highpressure
(150-300 psi) wastewater.
Available in sizes 1 to 4 in. with all
stainless-steel construction, the new
valve provides maximum corrosion resistance.
The lightweight, low-profile
design also operates without linkages
to assure proper operation and increased
durability, and meets AWWA
C512 requirements. - DeZurik, Inc.,

Bluetooth for level
and pressure transmitters
This level and pressure instrumentation
specialist has brought a Bluetooth
solution to the market (photo). A new
generation of the universal display and
adjustment module plicscom will allow
all the transmitters in the plics instrument
platform to be remotely operated
via an app - easily, conveniently
and securely - thereby enhancing
the concept of the modular instrument
platform plics. Its wireless Bluetooth
communication is suitable for
all industries and is particularly suited
for applications in difficult-to-access
locations, harsh industrial environments
and hazardous Ex areas. The
new module is backward compatible,
which means it can be used on the
entire installed base of more than 1.5
million plics sensors, many in operation
since 2002. - Vega Grieshaber

Dissolved-air flotation optimized
for exhaust-air treatment cycles
Traditional dissolved-air flotation systems
produce the flotation motive
water through air saturation of a partial
flow in the plant outflow. The saturation
usually takes place using multi-stage
pumps, which only run smoothly if they
are fed with pH-neutral wastewater that
is mostly free from solids. The injector
system developed by this company
achieves micro-bubble formation comparable
to saturation by pumps. The air
saturation of the partial flow is carried
out by an injector pressure container,
which is fed by a wastewater pump resistant
to solids and which can handle
both alkaline and acidic wastewater
without any problems. This enables
cycles to be driven through flotation
systems without chemical conditioning
or neutralization. The flocculant dosage
is required only to produce separable
flocs. If floating solids are present
without flocculation, a chemical-free
procedure is possible. - EnviroChemie

New high-density
cable entry solutions
This cable- and pipe-transit provider
has introduced a high density (HD)
cable-entry device for use in terminal
boxes and enclosures (photo). The HD
cable entry system meets challenges
with high cable density in applications
with that demand the utmost in safety,
and is available in versions for use in
potentially explosive atmospheres, as
well as for non-hazardous locations.
Besides providing environmental protection,
it helps designers and installers
save time, space and money. The cable
entry device consists of an AISI 316L
acid-proof stainless-steel frame and
industry-proven components, such as
sealing modules, making it adaptable to
cables of different sizes. A single cut-out
for the HD kit can accommodate up to
32 cables, which reduces the amount
of space required when compared to
32 traditional cable glands. Designers
and manufacturers cut weight by half
and increase cable capacity by up to
40% when compared to cable glands,
says the company. - Roxtec International
