14 Product Overview
3.4 Functional description Condair RO-A
A reverse osmosis system demineralises the supplied water by ltration at a low energy consumption.
The product of the system is "salt-free" water (also known as RO water, pure water or permeate) and is
up to 99% free of dissolved substances in the water and microorganisms, such as minerals and germs.
Reverse osmosis systems are used in pharmaceutical and food industry, heating and power plant engineering, as well as in air humidication. They are based on the economically favourable and continuous
process of water ltration by reverse osmosis. The reverse osmosis (by osmosis - diffusion through a
semi-permeable membrane) is a ltration at nanoscale level. It takes place at a differential pressure in
the reverse osmosis membrane.
The membrane is a wrapped lter, which is owed alongside by supply water. Filtered water ows under pressure through various membrane layers and is separated from the additives. The product (pure
water) is collected in the center of the membrane (diaphragm). Dissolved or entrained substances of the
inlet water are carried further along the lter. The product is ltered, depending on input water quality,
up to 99%. In the concentrate minerals and other substances ow lenghtwise through the membrane.
The concentrate is passed partly into the drain and partly mixed with the supply water to reduce water
consumption.
The pure water quality is usually controlled by a conductivity measurement of the product water. The lower
the conductivity, the higher the electrical resistance and the purer the product water. Filtration quality
depends on the particle size: gases due to their small molecular size pass through the membrane layers
and increase the conductivity of the product. For sensitive applications the quality of the feedwater and
the product water must be checked and optionally be periodically monitored.

Product (pure water)
Fig. 3: Functional diagram of the reverse osmosis membrane
The Condair RO-A pure water system is designed for demineralised water production. The system uses
special "low-energy" reverse osmosis membranes that are especially efcient: the membranes permit
under the listed supply water demands a particularly energy-saving water ltration at a desalination up
to 99%.
The Condair RO-A pure water system has a compact design and is characterized by an integrated
pre-lter, an internal 18 l pure water tank (RO-A40 and RO-A100) or an external 120 l pure water tank
(RO-A200 and RO-A300) and a control sampling point for the product. It is intended for rapid „movable“
installations and is bound only by hoses. The digital controller interface enables an accurate and simple
control as well as various setting and monitoring functions.

15Product Overview
3.5 Available options
Condair RO-A control unit The RO-A Control unit is used for Condair RO-A stand-alone
systems only.
The Condair RO-A control unit is equipped with a touch panel
to operate the control software, a operation status LED which
indicates normal operation (LED lights green), warning (LED
lights yellow) and error status (LED lights red).
Additionally the control unit features a USB interface for data
logging, exporting service and error histories and updating the
control and the driver board software.
Water softener "SoftCab 25 DR"
The water softener constitutes the rst stage in water treatment
and should be installed, if the values of the incoming water exceed
the limits specied in chapter 4.6.2 – Supply water specication.
The water softener reduces the water hardness to 0 - 1 °dh (0
- 1.8 °fh, 0 - 18 ppm).
The water softener works on the ion exchange principle. The resin
balls inside the water softener bind the magnesium and calcium
ions of the supply water and emit salt ions into the water. After
processing a specic amount of supply water the resin balls are
exhausted and must be regenerated. During this regeneration
process the bound ions are ushed out and replaced by fresh
salt ions. This process is fully automatic and takes approximately
2 hours. The regeneration process can be triggered time of day
or quantity controlled.
The water softener is supplied with a separate operation manual.
Note: the water softener SoftCab 25 DR provides a signal to
stop the operation of the Condair RO-A during the regeneration
process of the water softener.
If you use another type of water softener, the operation of the
Condair RO-A is not stopped during the regeneration process
of the water softener.

The carbon lter assembly serves as pre-lter and must mandatory be installed if the supply water is chlorinated. The carbon
lter assembly consist of a 5 µm lter (1) and a chloramine
carbon lter (2).
The carbon lter assembly has to be installed after the water
softener (if installed).
Leakage monitoring The leakage monitoring option consist of the leakage monitoring
control board and 1 to 3 oor sensors. The leakage monitoring
control board is connected to driver board inside the Condair
RO-A pure water unit and the sensor(s) are connected to the
leakage monitoring control board.
Important: the leakage monitoring does not override the direction
that the Condair RO-A system must be installed in a room with
a oor drain or in a tub equipped with a drain connected to the
building drain system.

36 Operation
5.5 Shut-down sequence for daily operation
Important!For reasons of hygiene, we basically recommend that the Condair RO-A pure water system
should be left switched on and the water supply should be left open even if no RO water is needed at
the moment. With the system switched on and the water supply left open, the water circuit is ushed at
regular intervals (every 24 hours) and hence the build-up of germs is opposed due to water stagnation
in the system.
If you have to shut-down the Condair RO-A pure water system (e.g. for maintenance purpose), perform
the following steps:
1. Close the shut-off valve in the water supply line.
2. Carry out a complete system ush as described in chapter 5.4.3 to release the pressure in the pure
water tank.
3. As soon as the LED lights up yellow switch off the Condair RO-A pure water unit via the unit switch.
4. Disconnect the Condair RO-A pure water unit and the water softener from the mains supply by unplugging the corresponding mains supply cable.
WARNING!
If the Condair RO-A pure water system is shut-down for more than 24 hours, there is danger of water
stagnation in the system, since the automatic system ushing function (every 24 hours) is inactive.
Please ALWAYS inform Condair Customer Service before recommissioning the system after a prolonged shut-down.
