GENERAL FEATURES
Options
Storing
and pumping
module
Standard pump Allows the circulation of the water on the plant side.
High head pump
Allows the circulation of the water on the plant side and guarantees a higher
available static head, suitable for high pressure drop plants.
Modulating pump
Allows the circulation of the water on the plant side with the possibility to set the
rotational speed of the pump in order to get the requested flow rate without the
necessity to install other setting devices.
Tank and
standard pump
Allows the circulation of the water on the plant side.
The thermal inertia of the buffer tank allows to reduce the number of compres -
sor starts and to guarantee a more stable flow temperature.
