4. Functional description and device compo-
sition
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/212°F
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 Structure and operation of the device
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 (W) 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 12 % 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).
Risk of skin burns!
During operation and for at least 10 mins afterwards the steam
nozzle is hot!
Do not touch!
Page 14
Risk of scalding!
During operation hot steam discharges from the nozzle.
Avoid direct contact with the visible steam cloud.
Due to foaming within the cylinder caused by contamination hot
water may trickle from the nozzle.
Keep clear!
Rotating parts!
During operation the cross-flow fan rotates.
Do not touch or block the fan during operation.

4.1.1 Fitting measures
Wall Distances [mm/inch]
Page 16
Please note
Wall Mounting
The steam humidifier must be installed vertically in order to function properly. Positioning should be such that draught effects are
avoided. The minimum mounting height is 0.15m/ 5.9 inch above
floor level. However, in order to avoid the risk of scalding a
mounting height of 2m/79 inch is recommended.
Risk of foot injuries!
Unit can drop during mounting by a single person.
Helping hand of a second person is required.
» Position the steam humidifier in the planned location,
adjust with spirit level and mark position of hanging
bolts. See also "Equipment Dimensions".
» Hang the unit onto bolts screwed into the marked posi-
tion.
4.2 Unit Installation Check
Please check the installation using the following list:
Does unit hang vertically?
Are wall distances to the unit within the range
Is the unit installed in such a way that draught effects
are avoided?
Are all bolts and clamps tightened?
