The O
2
vent line requires the most demanding
line management. Please study this section
carefully. The oxygen vent line carries around
0,25 Nm³/h (250 NL/h) of oxygen at up to 90 °C
out of the electrolyser. Additional components
are water vapour and a maximum concentration
of 2 % vol hydrogen. The water vapour sums up
to around 10-25 ml/h.
Caution! Never obstruct the output of the O
2
vent line
–
do not place any check valves,
or other system components which might block or close the line.
Ensure that the condensed water is not allowed to accumulate in the vent line and can
drain safely. Make sure that no obstacles are blocking the line. This includes condensed
water freezing inside the pipes.
Regularly check the vent line for a build-up of obstructions.
It must always be open at atmospheric pressure. If necessary, use a water trap and
heater to avoid pressure from building up.
This line contains hot gases! Handle the output and the pipe with care and do not touch
it during or directly after operation as the pipe itself, connected parts and the gases at
the outlet are hot and can create injuries and damages.
Please be aware that when larger hydrogen systems are created by putting together
several modules, the piping downstream may have to be sized accordingly. It is the
operator’s responsibility to ensure adequately sized piping is selected, which does not
limit the air flow. The operator must ensure that the outlet satisfies all relevant local
rules and regulation, in terms of the safe dispersion of the vented gas, noise emission,
risk assessments, maintenance, a satisfactory safety concept being utilised, and all other
relevant areas.
I
t is the operator’s responsibility to
regularly check and maintain all pipes.

setup.
