B GSE Group began
manufacturing the CoolJet
Hose Retriever in 2019 in
Morgantown, West Virginia.
The B GSE CoolJet Hose
Retriever deploys only the
amount of hose needed.
popular passenger boarding bridge manufacturers in the U.S.
In addition, he says the company has supplied combination
mounting systems to include mounting 400Hz and cable coilers
- all organized under the passenger boarding bridge cab.
Main Components
The main components of the CoolJet Hose Retriever system
include the hose, which is a flexible fabric hose made with
yellow PVC with an insulating layer. The hose sections are
joined by a zipper and a protective band with Velcro. Standard
hose lengths are 68 and 91 feet, while other lengths are
available upon request. The width of the hose is 35.5 inches.
Four individually powered ribbed belts run along the outside
of the wire-wound spiral hose and draw the hose into a
storage tube. Bullerdick says extraction and retraction processes
are smooth as a drivehead uses four concentric drive
belts powered by four speed-controlled motors. The hose
system's speed is programmable, and sensors stop the hose
when it is fully extended or retracted.
When the hose is in motion, the hose management
system (HMS) is interlocked to the PCA to prevent it from
running. The HMS also is interlocked to the boarding bridge
to prevent it from moving until the hose is fully retracted.
Only the amount of hose required needs to be extracted,
which Bullerdick says is often much less than the total hose
length. With a shorter hose and less need to bend or kink
the hose, there also is less temperature loss.
When not in use, the hose is protected in the storage tube,
reducing overall hose wear.
The PCA unit is oriented in the optimal position for
airflow, Bullerdick says, thereby reducing pressure and
thermal loses.
" HVAC is a precious commodity, " Bullerdick says. " The
moment the air leaves the source of production, it is either
warming up, cooling off or slowing down, which in all cases
is not in the direction you want it to go. In developing an
HVAC or PCA system, your system needs to look at how
to improve delivery. General rules in developing a good or
great system include: limit distance of delivery, limit how
many times you have to change directions of the airflow
and look to eliminate any restrictions or kinks in delivery.
The system B GSE has put together is the most direct,
straight and obstruction-free path from the PCA unit and
the aircraft. B GSE has studies that show airflow and air
temperature improvements of 20 percent or more compared
to any other system installed. Having a system design that
improves performance by 20 percent means there are consequently
energy efficiencies. The design and materials used
in the CoolJet HMS unit additionally help minimize losses by
ensuring smooth, corrosion-resistant airflow. "
System controls include the electronic control and command
panel, installed at the foot of the gangway, which
houses the fixed control devices - including a diagnostic
touchscreen and local redundant operator control panel.
Also included is a radio control system with a wireless
transmitter mounted on the HMS body, and a wireless
receiver and remote operator panel mounted on the aircraft
connector of the hose. The transmitter contains the
extraction and retraction controls.
" The CoolJet has been very well received, " Bullerdick says.
" We have worked very closely with our customers in launching
this product in the USA since 2019 and we have found
the design to be robust and reliable, as expected given the
20-year history overseas. The results have been impressive
with the ability to fit on almost any passenger boarding
bridge with minimum impact to bridge wear and maintenance
while greatly increasing the use of our customers
investment in 'green' GSE technology.
" On several occasions the operators would describe to our
technicians how effective and useful the product is. One
even approached us while changing a hose because he was
concerned we were taking it out of service and he didn't
want to lose it. "
