5 µm fine filter incl.
pressure reducer
Pressure reducer preset to 2.5 bar, incl. pressure gauge.
Inlet solenoid valve
During permeate output, this valve is always open. Following the system
stop (tank full), the valve remains open for the programmed flushing time
of the membranes. Visual indication in the control unit
.
Pressure switch
Pressure booster pump
Switches the pressure booster on when water is required, and off again
after water withdrawal ends.
Flushing solenoid valve
Opens after the level control
in the tank reports "FULL" to the control
unit for a set time. The solenoid valve also opens in the event of
system malfunctions and always in conjunction with the inlet solenoid
valve .
Needle valve, concentrate
To set the feed water-dependent "concentrate" volume flow to the drain.
During permeate output, this portion of the water flow permanently flows
to the drain.
High-pressure pump
Pump unit that generates the operating pressure required for the
membrane. Pump operates on permeate request from the level
control
(LB switches) located in the permeate tank. A control valve
for adjusting the operating pressure is integrated in the pump head.
Visual indication in the control unit
.
Membrane
Reverse osmosis membrane to generate the permeate.
AVRO treatment unit
AVRO treatment unit to generate seed crystals.
Level control
Float level control for controlling the water level in the permeate tank
(TS version only).
Booster pump
Pressure booster pump feeds permeate into the consumer network
(only TS version).
Control unit
Microprocessor controller that in conjunction with the respective units,
regulates the permeate production and the supply of consumers
downstream.
Flow sensor, concentrate
Registers the concentrate volume and sends pulses to the control unit.
Visual indication of the permeate volume in the control unit
.
Flow sensor
Permeate
Records the permeate volume and sends pulses to the control unit.
Visual indication of the permeate volume in the control unit
.
Diaphragm expansion tank Permeate buffer to reduce the switching operations of the DE pump.
Pressure switch
High-pressure pump
To prevent the high-pressure pump from running dry. Switches time-
delayed after the solenoid valve has opened
. Visual indication in the
control unit
.
Connection ½" (DN 15)
male thread
