4. Functional Description and Device Composition
4.1 Mode of Action
Making use of the frictional heat caused
by current flow in a water tank
The HygroMatik 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 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 Mechanical construction
The MiniSteam humidifiers are designed for
wall mounting. For maintainance purposes,
the steam cylinders are separable in the middle.
Page 10
4.3 Operating sequence
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)
steam cylinder (16)
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 period of heating up, the water
between the electrodes starts boiling and
then vaporizes. The vaporization lowers the
water level in the steam cylinder, reducing
the output provided. To compensate for that,
fresh water is fed into the steam cylinder
every now and then by opening the intake
solenoid valve.
Humidifier power usage is continuously monitored. With a cold start-up, the nominal current increases to 113% 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.
*)
feeds water into the
*)
.
With normal water quality the blow-down loss
rate lies between 7 and 15 % of the amount
of steam produced. Depending on water
quality, a full steam cylinder blow-down is run
every 3 to 8 days.
Mineral deposits settle in the open area
below the electrodes and are removed
through periodic maintenance. The blowdown 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.
On blow-down, water flows from the pump
into the drainage system.
For maintainence purposes, the cylinder
water may be pumped out by pressing and
holding the control switch in the „II“ position.
Monitoring max. level
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 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 blowdown pump 32)
*)
. The functioning of the
blow-down pump is continuously monitored
during operation. If the pump is damaged, the
steam humidifier shuts down.

5. Mechanical installation
Risk of foot injuries!
Prevent unit from dropping during installation!
Helping hand of a second person is advisable.
Risk of electrical shock!
Hazardous electrical voltage.
During installation, the unit must be disconnected from power supply.
5.1 Environment parameters to be met
• By design, HygroMatik steam humidi-
fiers are not qualified for outdoor installation (electronical components and
water-bearing parts may be damaged)
• Ambient temperature must lie between
+5 and +40 °C (+41 and +104 °F) in
order to protect the unit electronics
against damage; frost may damage the
steam cylinder, the solenoid valve and
pump, as well as make hoses burst
• Installation in a closed room requires
aeration and, eventually, temperature
conditioning in order to meet the a.m.
environmental conditions
• Relative humidity must not exceed
80 % r.h., since values beyond may
lead to electronic malfunction or
damage
• The steam humidifier rear panel heats
up during operation to a maximum of
70 °C (158 °F). Take care that the construction on which the unit is to be
mounted is not made of temperaturesensitive material
• Protection class IP20
5.2 Mounting recommendations
• Mount the unit on a stable, preferably
solid wall offering the bearing capacity
required (s. unit technical specifications), using the mounting material supplied with the unit. If such a wall is not
at hand, the unit may be attached to a
stand bracket firmly bolted to the floor
• The minimum clearances indicated in
the below figures must be observed in
order to ensure adequate unit ventilation and allow for unobstructed access
in case of maintenance
• The steam humidifier should be mounted in a position so that draught effects
are avoided. Minimum mounting height
above floor is 150 cm (59 inch). In
order to keep out of harm‘s way of scalding in the nozzle area with steam
emission with a temperature of 100 °C
(212 °F), however, it is recommended
that the steam humidifier is positioned
in a height of 2.0 m (79 inch).
• Make use of existing water connections
for supply and draining
• Hoses must be laid at a consistent 5 to
10 % incline/decline; sagging and kinking prevention is a must
3OHDVHQRWH
In order to achieve equal electrode depth of
immersion, plumb and level installation of the
HygroMatik humidifier is required.
