Selection Criteria; Operating Limits; Project Data - AERMEC NRA 0800 Manual Tecnico

The devices in their
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
