Fine filter incl.
pressure reducer
Pressure reducer preset to 2.5 bar, incl. pressure gauge.
Inlet solenoid valve
During the permeate production, this valve is always open. Fol-
lowing the system stop (tank full), the valve remains open for
the programmed flushing time of the membrane. Visual indica-
tion in the control unit .
Pressure switch for mini-
mum pressure of high-
pressure pump.
To prevent the high-pressure pump from running dry. Switches
time-delayed after the solenoid valve has opened . Visual in-
dication in the control unit .
Flushing solenoid valve
Opens after the pressure switch “switch-off pressure” has
reached the set pressure. The solenoid valve also opens in the
event of system malfunctions and always in conjunction with the
feed water inlet solenoid valve . Visual indication in the con-
trol unit .
Needle valve, concentrate To set the feed water-dependent "concentrate" volume flow to
the drain. During permeate production, this water constantly
flows to the drain.
High-pressure pump
Pump unit that generates the required operating pressure for
the membrane and for the filling of heating water systems.
Membrane
Reverse osmosis membrane to generate the permeate.
AVRO treatment unit
AVRO treatment unit to generate seed crystals.
Control unit
Microprocessor controller that in conjunction with the respective
units, regulates the permeate production and the supply of con-
sumers downstream.
Flow sensor, concentrate
Records the concentrate volume and sends pulses to the con-
troller. Visual indication of the concentrate volume in the con-
troller .
Flow sensor, permeate
Records the permeate volume and sends pulses to the control-
ler. Visual indication of the permeate volume in the controller .
Diaphragm expansion tank Permeate buffer to reduce the switching operations.
Pressure switch switch-off
pressure
Switches the reverse osmosis on when water is required, and
off again after water withdrawal ends.
Connection ¾“ (DN 20)
male thread or GEKA
Concentrate to drain.
Connection ¾“ (DN 20)
male thread or GEKA
Feed water.
Connection ¾“ (DN 20)
male thread or GEKA
Permeate/consumer.
Control valve for operating
pressure with pressure
gauge
To set the operating pressure, with pressure gauge as visual in-
dicator.
