2.2 Type of Gas
Depending on the version of the manifold, for high purity
gases incl. 6.0. See gas compatibility table Chapter 10.
2.3 Devices for requiring acceptance
plants
Details of required test certificates or certificates for materi-
als, tightness, etc. must be known when the order is placed.
2.4 General conditions for operation,
transport and storage
Ambient temperatures: -20°C to 50°C
Transport and storage: -20°C to 55°C
Atmospheric conditions:
rel.Humidity: 50 %at40°C
90 %at20°C
Environment: ambient air free of unusual quantities of dust,
acids, corrosive gases or substances such as
smoke, steam, oil vapor, etc.
Note: Use of pressure control panels unprotected out-
doors will impair the quality of the gases and can en-
danger the functional safety.
Deviating conditions can be agreed between the manufac-
turer and user upon.

2.6 Intended use
The pressure device is intended exclusively for the pressure
regulation of gaseous media from pressurized gas cylinders.
Any other use or use beyond this is considered to be not in
accordance with the intended use.
Intended use also includes
• observance of all instructions in the operating manual,
• observance of the inspection and maintenance work,
• observance of the type plate and the data sheet
2.1 Function
Pressure manifolds are used as central supply system for
technical and high-purity gases to supply one or more points
of use. The points of use are are supplied via a piping system
connected downstream the manifold.
Pressure control panels are available in various designs:
1. One-sided for connection of one or more cylinders.
These stations are used wherever a working process
can be interrupted due to a gas shortage or where the
gas consumption is so low that a cylinder change can
be calculated.
2. Manual changeover for connection of 2x1 or several
cylinders stored on two sides. The area of application
of this design is everywhere, where a process cannot be
interrupted due to a lack of gas, but a manual process
cannot be interrupted due to lack of gas, but a manual
changeoverispossible(e. g.duringnormalworking
hours).
3. Automatic changeover for connection of 2x1 or more
cylinders stored on two sides. If a working process runs
for a longer period of time and cannot be interrupted due
to lack of gas and a manual changeover is not possible
intermsoftime(e. g.outsideworkinghours,atnightor
at the weekend), then the use of these stations is re-
quired.
4. All pressure control panels can be supplied with pres-
sure transmitters. For flammable gases as Ex-version,
also for Ex-zone 1+2 applicable. The cylinder pressure
is measured in conjunction with a signal device which
indicates the level of ga in the cylinder. If the pressure
is below of a warning value, an alarm will be triggered.
5. Stations for oxygen, nitrous oxide and carbon dioxide
can be supplied with gas heaters.
6. If larger quantities of gas are required, it is of course
possible to luse cylinder bundles, which can be con-
nected via a high-pressure hose (please note the max.
flow rate of the station).
7. Pressure control panels can be extended as required by
retrofitting extension modules. The respective cylinder
pressure(max.200/300barat20 °C)isadjustedbythe
pressure regulator to the desired outlet pressure. The
exact parameters can be found from the data sheet or
product catalog.
8. A line shut-off valve should be installed in the pipeline
downstream of the battery pressure regulator. A protec-
tion against excess pressure of the main piping is man-
datory, here we recommend the installation of a suitable
safety valve. Options esspecially for the manifolds are
listed in the data sheet under “Options”.
