Gas sampling and gas conditioning technology 4-2.1.1-ME
N O T E !
The following minimal gas flow rates have been determined on the
basis of the requirements of the maximum pressure on both sides
of the gas measuring pumps N3-KPE and N9-KPE:
N 3 KPE approximately 60NL/h air,
N 9 KPE approximately 200NL/h air
Premature damage can be caused to the pump membrane if less
than the minimal total amount of flow is extracted as a result of
excess pressure.
In the event that long-term measurements are carried out whereby
the gas contains a high level of dust, it is necessary to utilise a
suitable sample gas probe in order to protect the sample leads
from clogging-up.
14 CLOSING DOWN
N O T E !
The area in which the equipment is situated when not in use must
be kept free of frost at all times.
There are no special regulations to be observed if the gas conditioning and sampling system is to be
closed down for a short period of time.
In the case of a long-term closing down, for example after a series of measurements has been
completed, it is recommended to backflush the gas conditioning system with ambient air or inert gas.
Under normal conditions, the equipment only needs to be backflushed for 3 to 5 minutes.
Condensate residue should also be removed from the system.
W A R N I N G !
Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!
15 MAINTENANCE
Before the maintenance work is carried out, it is necessary that the specific safety procedures
pertaining to the system and operational process be observed!
W A R N I N G !
Dangerous voltage. It is necessary to take the equipment off the
mains before any assembly, maintenance or repair work is
carried out.
In order to do this the main switch should be turned to the
position “O” and the mains plug should be removed from the
mains plug socket!
