6. OPERATIONAL LIMITS
The units, in standard configuration, are not suitable for instal-
lation in salty environments. The maximum and minimum limits
for water flow rate to the heat exchanger are indicated by the
pressure drop diagram curves.
For functioning limits, please refer to the diagrams below, valid
for ∆t = 5 °C.
ATTENTION:
Use of produced water with a temperature lower than
4 °C is only allowed by specific envisioned versions.
(Versions Z-Y).
If the machine is to be operated out of the limits indicated in the
diagram, please contact Airedale technical support dept.
If it is installed in a particularly windy zone, a windbreak should
be provided to avoid unstable operation of the DCPX device.
