Optimized safety and efficiency
in confined-space operations
The new X-Viz confined space monitoring
system (photo) is a complete
safety-monitoring system designed to
meet OSHA requirements during plant
turnarounds. By integrating gas detection,
video monitoring, alarms and access
control technologies, X-Viz allows
fewer safety attendants to remotely
monitor a greater number of confined
spaces. It also reduces overall labor
costs and delegates safety supervision
to skilled specialists. The high-quality,
real-time video footage allows safety
professionals to exponentially increase
the level of safety at a reduced cost. -

The Neles Q-Disc butterfly valve (photo)
has a new high-performance feature
to help with flow balancing in control
valve applications. Q-Disc is specifically
designed for control applications.
One of its key benefits is that it helps to
avoid oversized actuators for controlvalve
packages, which saves energy
and costs. Designed for challenging
flow conditions, Q-Disc can be utilized
to avoid cavitation in low opening angles,
and it also provides market-leading
noise reduction capabilities - even
up to 12 dB in certain flow conditions,
the company says. Q-Disc also helps
in optimizing the entire valve-actuator
package by making it possible to reduce
the impact of dynamic torque
caused by the flow. Q-Disc is available
as a modular option for a wide range of
butterfly valves, and it can be used for
a temperature range up to 600°C. -

A compact pelletizing plant
for iron-ore processing

This company has optimized its existing
induration technology, offering
and launched its Compact-sized Pellet
Plant (photo). The plant design is
based on a 3-m wide indurating machine,
building on the state-of-theart
design of the company's larger
(4-m wide) product range. The new
compact plant offers the same plant
performance and product quality as
the larger-size plants. Three standard
A new type of pellet mill for
producing green forage
Specially developed for green forage
pelleting, the 55-1500 pellet
mill (photo) is designed to produce
smaller and thinner pellets, as well
as coarser grass cobs. The pan
grinder rollers, measuring 450 to 550
mm, with a speed of only 2.5 m/s,
enable very good defibration of the
product. Due to the larger die diameter
of 1,500 mm and a larger, open
perforated surface, the 55-1500 easily
processes higher volumes than
the company's 45-1500 pellet mill,
while achieving an increase in output
of up to 50%. It also requires only
one motor instead of two as before.
This makes the machine particularly
energy-efficient, while offering low
maintenance. Its footprint is identical
to that of the 45-1250 pellet mill, so
it can be easily integrated into existing
drying plants. - Amandus Kahl

Tools for improving wire
connections to terminals.
Properly installed ferrules provide dependable
wire terminations to both
screw and push-in terminals, but
installers and technicians need suitably
rated parts and associated tools
for making these connections. This
company has therefore introduced
a complete product line of S3TL series
ferrules, wire strippers, crimpers
(photo) and screwdrivers. The S3TL
ferrule product line includes various
sizes accommodating wire gauges
from AWG 26 to AWG 8, each with
one or two wires, depending on part
number. Each ferrule incorporates an
electrically insulated cover, which is
color-coded using the German Weidmüller
standard, for easy recognition
by installers. The ferrules are UL
486F certified when used together
with S3TL series crimping tools. -
