6 SELECTION CRITERIA
6.1 OPERATING LIMITS
The devices in their standard
configurations are not suitable for
installation in salty environments. The
maximum and minimum limits for
the water flow rate to the exchanger
are indicated by the curves of the
pressure drop diagrams. For the
operating limits, refer to the diagrams
below, valid for ∆t = 5°C.
WARNING:
-
operation with a processed water
temperature of less than 4°C is only
allowed for the versions specifically
designed for this (version YA).
- if you want to operate the machine
outside the limits indicated in
the diagram, please contact the
AERMEC technical/commercial
office.
- if the machine is positioned in
particularly windy areas, it is
necessary to install windbreak
barriers to avoid the inconstant
operation of the DCPX device.
