6.5 Setting of the system pressure
Once flushing is complete, the diagram expansion tank
has to be connected to the connection set respectively
the safety group. The required inlet pressure of the
diaphragm expansion tank has to be determined first
and the tank has to be filled with nitrogen accordingly.
The required inlet pressure of the
diaphragm expansion tank as well as the
system pressure depends on the spatial
and performance-related parameters of the
solar plant. The technical service of the
company Oventrop will support you in the
design of an energy efficient solar plant and
the determination of all required operating
pressures.
