A Word about Water Quality
The mode of operation of all electrode steam humidifiers is based on the fact that water contains
minerals and is therefore conductive.
• "normal" tap water is ideal.
• but what is "normal" tap water exactly?
Users of HygroMatik units in the most diverse areas consider their tap water "normal."
HygroMatik typically defines "normal" as feed water with a conductivity between 200 and 500 µS/
cm (microSiemens per centimeter) at 15° C.
Some areas, however, are supp lied with tap water whose quality is outside the parameters specified by HygroMatik. If the HygroMatik steam humidifier's control is not adjusted correctly in these
areas, the unit cannot perform optimally. For example, the electrodes could wear out particularly
quickly or the steam production could be too low.
The operational parameters set by HygroMatik in the factory are intended for normal tap water.
However, they can very easily be reprogrammed to fit the special requirements of a particular
area. In addition, it is possible to install a plastic star in the cylinder in order to increase the life
span of the electrodes or to provide a flushing mechanism to extend maintenance intervals.
Because of this you should monitor your new unit during initial operation. Make sure that it has
been properly installed and is operating to your satisfaction.
Consult your HygroMatik specialists. We will test the quality of your water and advise you on
installation and initial operation. Your HygroMatik steam humidifier will be carefully adapted to
your particular application.
Warning, Hazardous Voltage: All work to be performed by trained personnel only.
All electrical installation and servicing of the electrical components of this unit to be
performed by qualified electricians only. Disconnect power supply before installation
and servicing!

4. Operation and Installation
4.1 Mode of Operation
The HygroMatik steam humidifier utilizes the conductivity normally present in tap water for steam production. Electrodes
inside an enclosed steam cylinder are immersed directly into the
tap water. They are connected to the alternating current.
The conductivity of the water generates an electric current
between the electrodes. In this way, the electric power supplied
is converted directly into heat without energy loss.
The amperage is a function of the available voltage, the
immersed electrode surface area, the average distance between
the electrodes and the water conductivity. The steam output of
the humidifier is determined by electric power usage, which is
regulated by increasing or decreasing the immersed surface
area of the electrodes.
Concurrently, a self-regulating control keeps conductivity within
a specified range.
The steam produced has a temperature of about 100°C with
minimal excess pressure ("pressureless steam"). It is largely
free of minerals and germ-free. Mineral deposits typically remain
behind in the cylinder.
4.2 Installation and Operation
By pressing the control switch („Pos. I”) the humidifier is turned
on. When the controller specifies an increase in humidity, the
main contactor is switched on and the electrodes (48) are supplied with power. The water inlet solenoid valve (25) feeds water
into the steam cylinder (16+19).
As soon as the electrodes are immersed, the current begins to
flow. The water is now heated. When the pre-selected output is
reached, the control turns off the solenoid valve and interrupts
the water supply.
After a short heating up period, the water between the electrodes begins to boil and vaporize. The vaporization lowers the
water level in the steam cylinder, reducing the output provided.
The inlet solenoid valve, equipped with a fine mesh filter, intermittently admits fresh water.
Humidifier power usage is continuously monitored. With a cold
start-up, the nominal current increases to 125% in order to
achieve quick-start output parameters. This activates the electronic overflow limiter which causes a partial draining of the cylinder. This reduces the immersed surface area of the electrodes,
lowering power usage.

The concentration of dissolved salts increases over time, which
can lead to a rise in the conductivity of the water. If this continues, conductivity may increase until a short circuit occurs. This
could damage the unit, but in any case would significantly
reduce the life span of the electrodes.
For this reason, regular, periodic blow-downs of some of the
concentrated water are very important. Following this procedure
as recommended provides stable cylinder water conductivity as
well as minimal water loss for the expected service life of the cylinder.
Water blow-down is performed by a blow-down pump (32). The
functioning of the blow-down pump is continuously monitored
during operation. If the pump is damaged, the steam humidifier
shuts down.
With normal water quality, the blow-down loss rate is between
7% and 15% of the amount of steam produced. The steam cylinder requires complete drainage every 3-8 days, regardless of
the water quality.
Mineral deposits settle in the open area below the electrodes
and are removed through periodic maintenance. The blow-down
pump itself has wide openings and can flush out smaller pieces
of mineral deposit. This extends the service life of the unit and
reduces the required maintenance interval.
During blow-downs, water flows from the pump into the drainage
system.
A sensor electrode (10) monitors the maximum
water capacity
of the cylinder. When the water level reaches the sensor electrode, the water supply is interrupted. This can occur when the
water has low conductivity or when the electrodes are worn out.
In the case of low water conductivity, however, this state usually
lasts only a short time. The built-in control and the large area
electrodes combine to produce a rapid rise in conductivity by
increasing the concentration of the water.
The steam cylinder consists of a top (16) and lower (19) part
joined with a cylinder flange. The seal between the cylinder and
cylinder base (37), as well as between the top and lower part of
the cylinder, is maintained using an o-ring (35+17).
For maintenance the cylinder can be drained by pressing the
control switch „Pos.II”.

5.1 Steam Humidifier Operating Environment
Note: When selecting the installation site for the steam humidi-
fier, note that:
• Ambient temperature must be between +5° and +40° C.
Relative humidity must not exceed 80% RH.
• An Installation in a closed room requires aeration and if
neccessary temperature conditioning in order to reach
the above mentioned environmental conditions.
• The minimum clearances indicated in the diagram
below must be observed; these are necessary to
ensure adequate ventilation for the housing.
• HygroMatik humidifiers are not suitable for direct outdoor installation.
• The steam humidifier should be installed as close as
possible to the steam manifold. Optimal performance is
guaranteed only with short lengths of steam and condensate hose
.
• Hoses must be laid at a consistent 5-10% incline to prevent sagging and kinking
.
• The rear panel of the steam humidifier heats up during
operation (to a maximum of 60°C).
Take care that the
construction on which the unit is mounted is not made
of temperature-sensitive material.

5.3 Absorption Distance BN
The "absorption distance" (BN) is defined as the distance from
the steam feed to where the steam is completely absorbed in the
treated air. Inside the absorption distance, steam is visible as
mist in the air stream.
Condensation may collect on anything installed inside the
absorption distance.
Although steam outside the absorption distance (B
N
) is com-
pletely absorbed, it is not yet evenly diffused in the duct. If you
plan to install any parts or devices inside the absorption distance, such as sensors or elbows, we recommend increasing
the absorption distance using the formulae below. The absorption distances required for certain installed fittings are distinguished by separate symbols and calculated as a multiplier of
the absorption distance B
N
.
The absorption distance has no fixed value, but depends on
many factors. These are depicted in the absorption distance
nomogram below.
5.3.1 Determining the Absorption Distance
To determine the absorption distance, the following parameters
are required:
• Air humidity before humidification x
1
in g/kg.
• Air temperature after humidification t
2
in °C (with steam
humidifiers the change in air temperature due to humidification may be disregarded t
1
or t2).
• Specific increase in humidity x in g/kg (can be determined in the h,x diagram)
• quantity of steam introduced in kg/h.
• air speed w
L
in m/s in air duct
• Total length l
D
of the steam manifold installed in the air
duct

Length ID of the usable steam manifold depends on the dimensions of the air duct. The length of the absorption distance can
be reduced by using multiple steam manifolds (also see section
on the steam manifold).
Method:
Graphically determine absorption distance B
N
using the absorp-
tion distance nomogram (also see Section „Absorption Distance
Nomogramm“). Enter the value of the parameters enumerated
above into the respective quadrants. The resulting point of intersection indicates the value of the desired absorption distance
B

.
