Innovations
ztC Advisor and ztC Edge. The
web-based solution is architected
so that ztC Edge platforms initiate
sessions and periodically push
information to ztC Advisor, which
minimizes cybersecurity risk by
limiting data transfer.
* Integration with Stratus Service
Portal and ztC Edge platforms,
allowing customers with portal
access to use their same credentials
to access ztC Advisor. One-click
enablement from the ztC Edge
Console automatically sets up the
corresponding ztC Edge platform to
be visible and present data through
ztC Advisor, minimizing setup and
configuration time.
ztC Advisor and its remote system
monitoring capabilities are compatible
with ztC Edge platforms running SRL
2.2, and build on updates to ztC Edge
platforms, released earlier this year, that
address customers' most pressing needs
for enhanced security, monitoring and
performance at the edge.

FIG. 4. New Hydra-Cell Q330 Series pumps
by Wanner Engineering Inc.

Seal-less pumps without
seals or packing
Wanner Engineering Inc. has introduced its new Hydra-Cell Q330 Series
pumps (FIG. 4) that feature a seal-less
design to avoid the maintenance problems of mechanical or dynamic seals and
packing that can leak and wear. They are
designed for a variety of high-capacity
applications, including saltwater disposal
(SWD), saltwater injection, bulk transfer and hydraulic lift in oil fields, as well
as steam generation, reverse osmosis in
water and wastewater treatment, mine
dewatering, boiler feed and high-pressure
cleaning. Models are available to meet
API 674 performance standards.
The new Q330 medium-pressure
models offer flowrates up to 153 gal/min
(579 l/min; 5,247 bpd) and a maximum
pressure rating of 3,500 psi (241 bar).
New high-pressure models offer flowrates
up to 118 gal/min (446 l/min; 4,047
bpd) and a maximum pressure rating of
4,500 psi (310 bar).
The seal-less design means that HydraCell Q330 pumps do not have a leak path
and therefore eliminate hazardous VOC
emissions and the clean-up and disposal
costs of packed-pump leakage. This also
eliminates the need for external lubrication and maintenance as well as plunger
wear problems associated with packing.
Hydra-Cell Q330 Series pumps can
run dry without damage, will operate
with a closed or blocked suction line, and
can pump hot abrasive fluids effectively.
The patented, seal-less Hydra-Cell Q330
Series pumps employ hydraulically-balanced, multiple diaphragms that enable
the pump to handle high pressures with
low stress and process abrasive particulates up to 800 microns in size.

CO2 monitoring device

FIG. 5. Sensirion's SCD30 CO2 sensor.

Cleveron AG has chosen Sensirion's
SCD30 CO2 sensor (FIG. 5) for its new
CO2 monitoring device. CLEVER Sense
enables effective and smart ventilation in
closed rooms and impresses with its top
measuring accuracy and reliability.
More and more studies indicate that
CO2 can serve as a good indicator for
monitoring the air quality in closed rooms.
Since CO2 in indoor spaces almost always
originates from humans, conclusions can
be drawn about the risk of infection with
viral diseases such as COVID-19.

Especially in the cooler months of the
year, it is important to keep the air quality
high as people stay indoors longer than
in summer. Air quality in classrooms,
offices, meeting rooms, restaurants and
many other spaces quickly becomes poor.
Proper ventilation is therefore becoming
increasingly important.
This is where Cleveron and Sensirion
come into play. With CLEVER Sense,
Cleveron AG offers a smart solution for
monitoring CO2 concentration indoors.
With three levels that are based on a traffic light-red, yellow and green-the device shows the air quality in the room at
any given time. Operation is user friendly
via a web app or the integrated button.
The sensor used in CLEVER Sense
is Sensirion's SCD30 CO2 sensor. The
sensor, based on the established CMOSens® technology, impresses with its top
accuracy and reliability, as well as a small
form factor that allows easy integration
into applications.

New large enclosure
system for purge
and pressurization
Pepperl+Fuchs has introduced a Bebco EPS® purge and pressurization system
(FIG. 6) designed specifically for use with
large enclosures in Zone 1 hazardous areas. The 6100 series purge and pressurization system can purge an enclosure of
more than 450 ft3 (12.2 m3 ), making it
the largest purging system available from
Pepperl+Fuchs. The 6100 series system
is ideal for applications in the chemical/
petrochemical and oil and gas industries.
The 6100 series is a fully automatic
system that does not require an operator
to initiate purging or pressurization. It
offers optional temperature sensors that
can be mounted around the enclosure for
alarm notification or cooling. Additionally, there is automatic pressure compensation for excess leakage from the enclosure.
The 6100 system consists of a control
unit, vent, low-pressure sensor and optional temperature sensors. The control
unit allows users to configure the system
for size of motor, temperature switch
points, pressure switch points for leakage
compensation and shutoff pressure, extra
output for control or alarm, two selectable intrinsically safe inputs for various
actions, and up to three temperature sensor inputs that can monitor various points
