CANgas
The pressure can program for small quantities
As a leading gas manufacturer, Messer has a large
number of high-purity gases and gas mixtures in its
conventional cylinder gas program, generally in 10 or
50 litre cylinders. For many tests or measurements,
however, gases are only required in small quantities.
The residual gas left in the cylinders remains unused.
or gas mixture is needed. For these purposes Messer
offers an easy and uncomplicated system.
CANgas pressure cans are small, light, handy and can
be stored almost anywhere. The handling of pressure
cans could not be simpler having on site only the
needed quantity.
For checking sensors in explosion areas or for monitoring atmosphere at workplaces it does not always have
to be the heavy steel cylinder. All you need is a small
and light pressure can.
Pressure cans are made of aluminium. The lid valve is
closed against atmospheric pressure by means of a
spring. The tested pressure is 18 bar, so a maximum
filling pressure of 12 bar is permitted. As a disposable
container, the pressure can is suitable for aluminium
recycling after use.
Also for special applications in research and development sometimes only a small quantity of a certain gas
Fully automated filling of pressure cans
Filling is precision work
Pressure cans are filled in a fully automatic filling plant.
Gas mixtures, for example, are composed and homogenized in advance in a larger pressurized gas cylinder. We
execute purity analyses in each cylinder from which the
gas for pressure cans is taken, and randomly sample the
filled batches, all to ensure the perfect quality of every
pressure can.
Small, light and flexible: The withdrawal system for pressure cans
The basic elements of the system are the valves which
can be screwed directly onto the pressure can. Thanks
to only a few different components, you can achieve
maximum flexibility of application. The valves have been
specially developed for the pressure can program and
with their aluminium bodies they are light yet sturdy.
They are designed for a primary pressure of 12 bar. The
NPT 1/8” female thread on the output side permits a
wide variety of connections for gas transfer.

Pressure Regulator
The pressure regulator reduces the output pressure to
0.6 bar (fixed factory set). The flow rate can be adjusted
with the integrated dosing valve. The pressure in the
can is indicated at all times on the primary pressure
manometer. This valve offers:
• exact dosing at reduced working pressure
• virtually constant discharge pressure with falling
primary pressure
• Limitation of the pressurization in the connected
system (e.g. glass apparatus or measuring instrument).
We will be happy to help you choosing the required
withdrawal system.

Supply program for withdrawal systems
Dosing Valve
The dosing valve is used, if:
• pressure reduction is not necessary
• dosing only takes place for a short time (because of
the falling primary pressure, constant discharge over a
prolonged period is only possible with readjustment.)
• the connected system can withstand a pressure of
12 bar, or is open to the atmosphere
Connections
The connecting technology always provides the matching
output connections for your individual application
• Plastic hose spout, NPT 1/8" male
• Adapter 1/8” NPT male for the combination of
different equipment
• Clamping ring connection, stainless steel, 3 mm,
NPT 1/8" male

Top Valve
Due to its special construction the TOP Valve provides
additional options:
• Evacuation up to the closed TOP Valve of the
pressure can
• Low-contamination withdrawal
Accessories
• The manometer for primary pressure indication
• The float-type flow meter for indication of the withdrawal flow (marks at 10, 20 und 40 l/h)
• The septum for the withdrawal of small quantities for
the calibration of gas chromatographs
• The wall mounting for the safe storage of pressure
