Gardner Denver’s TR20 screw compressor provides compressed air for the efficient unloading of dry bulk products from road tankers
Gardner Denver drives home
compressor performance
A
t this year’s CV Show, held in Birmingham, UK, Gardner
Denver demonstrated the capabilities of its transport
solutions for the commercial vehicle market, in particular by
highlighting compressor performance.
Gardner Denver exhibited an Iveco Daily 40C14N V CNG van
operated by Cadent Gas and fitted with Gardner Denver’s latest
DLG Drive Line compressor and generator system.
The vehicle is the first CNG-fuelled Iveco Daily van in the UK to
feature on-board power. Meeting the latest market demands, the
system is lightweight, compact, quiet and easy to use, delivering
100 CFM (cubic foot per minute) at 6 bar and 80 CFM at 7 bar.
Gardner Denver’s on-board power technology uses the energy
generated by the compressor to operate paving breakers, air lances
and pneumatic mole equipment, while the 6 kVA generator will be
used to power fusion welders, pumps and other hand tools.
Andrew Savage, Gardner Denver UK highways & utilities sales
manager, explained: “With new government legislation coming into
effect, we saw an opportunity to install our DLG Drive Line
compressor/alternator systems onto alternatively-fuelled vehicles.
This takes advantage of changes to the category B driving licence,
allowing drivers to operate alternatively-fuelled vehicles plated at
4,250kg. This provides them with a greater carrying capacity when
responding to emergency call-outs.”
Alongside this, Gardner Denver also highlighted its TR20 screw
compressor, which provides compressed air for the efficient
unloading of dry bulk products from road tankers. The was fitted

Gardner Denver’s long-standing customer, Whitworth Bros Ltd.
The UK flour milling business, which has been a loyal customer
of Gardner Denver for a number of years, specified the
compressor to be fitted to a fleet of 16 new DAF tractor units,
growing its fleet of GD compressors to more than 80. The vehicle
is also be fitted with a remote-controlled tipping system, which
allows the driver to operate the tipping tanker from a safe
location while discharging the flour at a customer’s site. Gardner
Denver works closely with its customer base to ensure that all
their safety requirements are met.
The TR20 screw compressor provides flexible airflow, which
means it can discharge all types of bulk powder products from a
road tanker. The solution for Whitworth Bros Ltd has been set to
provide the perfect airflow of 750 cbm/h, ensuring flour products
can be discharged safely and efficiently.

Alltec’s 2nd gen monitors
A
lltec has released the second generation of its floating
roof tank monitors (FRTM).
This new generation has a smaller foot print, coming in at half the
size of the original. That means half the weight as well. Additionally,
the new version activates at 2 ohms, against the previous 10 ohms.
The GroundGuardian FRTM detects hazardous changes in
resistance of the electrical bond between the floating roof and the
storage tank’s grounding system. The unit will continuously monitor
for unsafe deviations in resistance produced by corrosion, product/
wax accumulation, or shunt breakage. By using an intrinsically safe
ground loop supervisor circuit, the state of the existing shunts are
monitored. If a dangerous state change occurs, the GroundGuardian
can notify the process control monitoring system.
Features include: unit status indicating lights, dry relay contacts
(DRCs) as standard, with other interface protocols available, initiating
external alarms, activating product transfer interlocks, updating time/
date stamp records, triggering lightning protection bonding
inspection/maintenance, housed in a NEMA 7X, UL 1203 explosion-
proof and dust-ignition proof enclosure suitable for installation in
hazardous locations.
Downtime and recovery costs from potential lightning strikes can
be very expensive and have
possible safety consequences for
personnel, strategic infrastructure
and critical storage tanks. Tank
replacement costs, losses due to
operational shutdowns, and
safety liability issues can be
minimised with the appropriate
use of modern lightning
protection methods. These can
entail an engineered mix of
structural air terminals,
equipotential bonding, and
grounding. The GroundGuardian
is claimed to offer an easy way to

the floating roof and the storage tank’s
grounding system
From the monitor’s intrinsically
safe rated subsystem, current is
passed to the optional remote I/O enclosure, which is rated for
installation on the storage tank shell wall.
The remote I/O enclosure connects to a self-retracting insulated
monitoring reel with a bond to the tank’s floating roof. A simple
reference connection is made from the monitor’s supervisor circuit to
the EFRT’s earthing/grounding system.
During conditions of less than 2 Ohm resistance, the green LED will
be on in the monitor’s front panel. When resistance exceeds 2 Ohms,
the GroundGuardian initiates an alarm state; two dry relay contacts
change state and the green LED on the front panel will shut off.

Loadtec sells marine arm division
W
oodfield Systems has bought Loadtec Engineered
Systems’ marine arm division.
Woodfield has been manufacturing marine arms since the 1950s.
Loadtec said the division’s sales have been very strong, from a
standing start, but it has reached a point where it needed to develop
and grow within a like-minded business.
Woodfield has the resources and ambition to support the Loadtec
product range and will complement the established Woodfield marine
arm brands. The core Loadtec marine team will also transfer to
Woodfield.
Loadtec Managing Director Alec Keeler said: “We have long enjoyed
a friendly relationship with Woodfield Systems and their enthusiasm
for this transaction made the offer a very compelling proposal for
both companies. We are excited to see how they will develop the
Loadtec marine arm brand using their resource and support activities
and we wish them well. Our people were key to the success of this
and we were very fortunate to have an excellent team on board.”
David Williams, sales director of Woodfield, said: “This is an exciting
time for us and the acquisition of the Loadtec marine loading arm
division will complement our existing range of marine loading arms.
Additionally, the extensive knowledge that comes with the personnel
joining from Loadtec, will strengthen and enhance the Woodfield
team.”
Loadtec Engineered Systems will continue to focus on its core
competence, road and rail tanker bulk liquid transfer, fall prevention
systems and marine gangways. Keeler stated: “The markets are
seeking more sophistication in their automation of manual processes
along with increased safety assurance. We are taking strong and
positive steps to lead the way with new products and packages that
represent the cutting edge of what is achievable in chemical plants
and terminals.”
