10.2 PRESSURE DROPS
DESUPERHEATERS
The NSB models with desuperheater
can have, depending on the sizes, up to
three desuperheaters (arranged paral-
lel to each other
NOTE
the plumbed parallel is the responsibili-
ty of the installer
The characteristics and the curves of
the pressure drops are shown below.
For the water produced temperature
values different from the rated, 45 °C,
the result obtained is multiplied by the
correction factor that can be obtained
