Minimum water flow
Maximum water flow
Water flow-rate
The design water flow-rate must be:
inside the exchanger operating limits (see the TECHNICAL
DATA chapter)
guaranteed also with variable system conditions (for example,
in systems where some circuits are bypassed in particular
situations)
If the system capacity is below the minimum flow, bypass the
system as indicated in the diagram.
If the system capacity exceeds the miaximum flow, bypass the
system as indicated in the diagram
Minimum system water content
Minimum system water volumes are described within chapter
TECHNICAL DATA and they have to be satisfied for a proper
functioning of the unit.
Flow Switch
The flow switch must be present to ensure shutdown of the unit
if water is not circulating.
It has to be installed in a duct rectilinear part, not in proximity
of curves that cause turbulences.
