Compressors and systems
Biomethane as a fuel
operation, the compressor module
delivers 8640 kg of biomethane in a
24-hour period. Integrated filter and
post-drying cartridges installed on
the high-pressure side clean the compressed
gas and remove residual
moisture from it.
As in most applications, the storage
is used here as a 3-bank system
consisting of three individual
sub-storages, the high, medium and
Fig. 5: B3360 Storage module
low banks. This division allows an
optimum utilization rate. Thanks to
the larger quantity of gas available,
ve hicle refuelling can be carried out
in immediate succession.
The filling and refuelling control
regulates the priority filling of the

(VRÜ)
high-pressure accumulator and the
sequential gas withdrawal from the
high-pressure accumulator. It is possible
to control one or more filling
lines.
The dispensing device can be
designed with a flow measuring
device (display of the dispensed
refuelling quantity in kg or m³) as well
as a display field with the indication
of the specific gas price as well as the
total price in the desired currency.
The filling and refuelling control system
regulates the filling process and
thus ensures economical refueling
with short filling times at the same
time.
For the operation of a public service
station, the use of a fuel dispenser
is required by law. The display
shows both the unit price, the quantity
refuelled and the final price at
the same time. The dispensers are
available with one or two hoses and
with one or two devices for mass
flow measurement. This allows either
separate or simultaneous vehicle
refuelling on both sides of the dispenser.
With an automatic fuel dispenser,
it is possible to realize an accounting
of the fuel data without a manned
cashier's store. With regard to operation,
the different fuel dispenser
models can be optionally tailored to
fleet card operation and/or credit
card operation. All of the company’s
large systems offer interfaces for
optional connection to an Internetcapable
PC or cell phone. This allows
the operator to monitor the operating
status remotely around the clock.
Comprehensive and seamless project
management – a core competence
According to customer specifications
and in close consultation, BAUER project
engineers first select the best
location for the filling station. Special
focus is placed on exact compliance
with applicable legal regulations.
By minimizing explosion
protection zones and tailoring the
size of the refuelling systems, the
supplier is able to find an optimal
solution for installation even in difficult
space conditions. After installation,
the complete piping of the sys-

tem including all pressure lines from
the compressor to the storage tank
and further to the dispensing point or
dispenser is carried out according to
the relevant guidelines. This is followed
by an inspection by an approved
acceptance organization, such as the
TÜV. The project team coordinates
the necessary scheduling with the
companies and authorities involved.
Service technicians carry out the
electrical wiring of both the compressor
unit and the dispenser/dispenser
in accordance with the agreed plans.
Only a high-voltage connection must
be provided by the operator. After
installation, the compressor unit is
booted for the first time and thoroughly
checked again.
The supplier takes over the entire
project organization. It ranges from
the installation and commissioning
of the compressor storage unit and
the dispenser technology to the precise
coordination of deadlines. As a
result, commissioning can usually
take place after just a few days. After
a successful assembly at the installation
site, the installation is inspected
by an expert. This acceptance at the
installation site is also carried out by
the service team together with the
respective supervisory authority. The
comprehensive service also includes
detailed instruction of authorized
