Product Overview

Circuits balanced with Autoflow
Autoflow balances the
hydraulic circuit
automatically, by
ensuring to each
terminal emitter the
design flow rate.
Even in case of partial
circuit closure by
means of the
regulating valves, the
flow rates in the open
circuits remain
constant at the
nominal value. The
system always
guarantees the
greatest comfort and
the highest energy
savings.
Modern heating and air-conditioning systems have to guarantee a high level of thermal comfort with a low energy consumption. This means
supplying the system terminals with the correct design flow rates, to produce balanced hydraulic circuits.

Circuits balanced with manual valves
Traditionally, hydraulic
circuits are balanced
using manual
calibration valves.
With these static-type
devices, such circuits
are difficult to balance
perfectly and have
operating limitations
in case of partial
closure by means of
the regulating valves.
The flow rate in the
open circuits does
not remain constant
at the nominal value.

Unbalanced circuits
In case of an
unbalanced circuit,
the hydraulic
umbalance between
emitters creates areas
with temperatures
which are not
uniform, and, as
a consequence,
problems with thermal
comfort and higher
energy consumption.
