6. ABOUT THIS DEVICE
The STULZ UltraWater is intended for the treatment of drinking water for use in ultrasonic humidiers.
Adiabatic humidifying systems produce cold mist and must be supplied with demineralized drinking water,
in order to ensure that the vibrating elements continue to function throughout the life of the system, and
to prevent any buildup of limescale in the system or in the humidied room. This can be achieved very
simply in practice by positioning the STULZ UltraWater reverse osmosis system upstream. The heart of
the STULZ UltraWater reverse osmosis system is a high-performance membrane, which removes chalk,
sediment and other undesirable substances from drinking water. Special features of this system are an
integrated pressure pump and two combination lter stages, which ensure low-cost operation and a long
service life.
During the production of demineralized drinking water, the STULZ UltraWater reverse osmosis system
removes
● 95% of all dissolved solids (minerals)
● 99% of all bacteria and viruses, and a high proportion of organic substances
● 99% of chloride
from the water.
The STULZ UltraWater is designed to demineralize drinking water, not produce drinking
water!
Depending on the untreated water, this water treatment system removes at least 95% of all salt
and minerals from the water. If this system is used in applications with little or no outside air supply
(e.g. equipment rooms) in combination with STULZ UltraSonic humidifying systems, it is essential
to prevent salt/minerals from being brought into the room via the air humidifying system and depos-
iting themselves on surfaces. For this purpose we urgently recommend the downstream use of a
deionization system (e.g. STULZ ion exchanger SD2800 – K85802).

If two solutions with different ion concentrations – aqueous solutions with different salt content – are sepa-
rated by a semi-permeable membrane, the solutions attempt to equalise the concentration. This attempt
results in ions from the aqueous solution, with the higher concentration trying to “migrate” to the side of the
semi-permeable membrane the lower concentration solution.
This concentration equalisation cannot occur in this way, as the membrane is impermeable for the ions.
Thus, the water molecules, which can penetrate the membrane, ow from the side with the lower concen-
trate to the side with the higher concentration to achieve the equalisation. This process continues until
the concentration equalisation of the ions on both sides has been achieved or so-called osmotic pressure
has become established on the high concentration side. This osmotic pressure is less than 2 bar in drink-
ing water and increases as the different in concentration rises. This process is known as osmosis and, in
nature, is responsible for regulating the water balance in cells.
The bursting of cherries is described below as a clear example of osmosis.
The starting point is a ripe cherry, whose skin is wet with water after a rain shower.
The rain water on the skin of the cherry represents a liquid with lower concentration of dissolved particles.
The cherry juice inside the cherries represents a liquid with high concentration due to the dissolved sugar.
The cherry juice attempts to equalise the concentration with the rain water and wants to diffuse towards
this water. However, this is prevented by the semi-permeable membrane, which retains the sugar mol-
ecules because of their size.
This results in a process in which the water molecules ow from outside into the inside of the cherry and
the pressure in the cherry increases until it can no longer expand and nally bursts.
As the name suggests, reverse osmosis is the converse of the osmosis process.
Tap water represents the side with high ion concentration and is forced towards the pure water with the low
concentration by application of an external pressure.
This externally applied pressure must be higher than the osmotic pressure. This is the only way in which
the water molecules can migrate against their natural osmotic direction into the area with lower concentra-
tion and the substances dissolved in the tap water cannot pass through the semi-permeable membrane
because of their size. Therefore, almost exclusively water molecules remain on the pure water side. The
substances remaining on the membrane must be continuously discharged to prevent clogging of the mem-
brane.

Reverse osmosis technology
If two solutions with dierent ion concentrations – aqueous solutions with dierent salt content – are separate
by a semi-permeable membrane, the solutions attempt to equalise the concentration. This attempt results in
ions from the aqueous solution with the higher concentration trying to “migrate” to the side of the semi-perme -
able membrane with the lower concentration solution.
This concentration equalisation cannot occur in this way, as the membrane is impermeable for the ions.Thus,
the water molecules, which can penetrate the membrane, flow from the side with the lower concentrate to the
side with the higher concentration to achieve the equalisation. This process continues until the concentration
equalisation of the ions on both sides has been achieved or so-called osmotic pressure has become estab -
lished on the high concentration side.This osmotic pressure is less than 2 bar in drinking water and increases
as the dierent in concentration rises. This process is known as osmosis and, in nature, is responsible for
regulating the water balance in cells.

Removes gaseous substances, e.g. chlorine and particles > 5µm.
Stage 2 TFC membrane (thin lm composite) 2 years 2 years
Removes hardness elements and other minerals, such as lead,
copper, chromium, mercury, sodium, cadmium, uoride, nitrites,
nitrates, selenium and organic substances with a high and
medium molecular weight, such as pesticide and drug residues.
Stage 3 Combination lter
(asymmetrical composite material) 12 months 12 months
Removes gaseous substances, e.g. chlorine, particles and odors.
1) At rates of up to 150 l/h. If the untreated water contains chlorine (concentration >0.1 mg/l), this reduces the lter service life by up to 50%!
2) The lter service life may be shorter or even longer in isolated cases, depending on the local conditions.
Regular visual inspections must be performed.
Note:
We recommend performing test measurements to determine conductivity over a longer period,
so that the cycle times can be ascertained for your particular application. For this purpose, we
recommend installing a measuring branch pipe in the device outlet.
