Circuits balanced with FlowCal™
FlowCal™ balances the hydraulic circuit by automatically controlling
the design fl ow rate to each emitter. Even with some circuits closed
by the control valves, the fl ow rates in the open circuits remain
constant at the nominal value. The system always provides the
greatest comfort and the highest energy savings.
