12.3 PRESSURE DROPS
All NRA models with desuperheater
are equipped with two (desuperhea-
ters in parallel).
NOTE
The parallel water connections is to be
made by the installer
Desuperheaters specifications and
pressure drop curves are given below.
For temperatures of produced water
other than 50 °C, multiply the result by
the correction factor that can be deter-
mined from the table at the bottom of
the page. 12.2.4.
The heating capacity available to the
total heat recovery is in rated condi-
tions:
Air temperature 35 °C
Water produced 50 °C
∆t 5 °C
Average water temperature °C
