Example
given: ϕ1= 30 %rh, ϕ2= 70 %rh
humidication distance B
N
: 1,4 m
(0.36 m for steam distribution system MultiPipe)
Note: If the humidication distance has to be reduced for technical reasons,
the amount of steam per basic unit must be divided between two steam
distribution pipes or the steam distribution system MultiPipe must be
used. If this is the case, contact your Nordmann supplier.
Minimum distances to be observed
To prevent the water vapour, that is emitting from the steam distribution pipe,
from condensing on downstream system components, a minimum distance
to the steam distribution pipe must be observed (depends on the humidi-
cation distance “B
N
”).
