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 con-
ductivity normally present in tap water for
steam production. Electrodes inside an
enclosed steam cylinder are immersed
directly into the tap water. They are con-
nected to the alternating current. The con-
ductivity 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 typ-
ically remain behind in the cylinder.
4.2 Mechanical Construction
The FlexLine humidifiers are designed for
wall mounting. For maintainance purposes,
the steam cylinders are separable in the mid-
dle.
Starting with the manufacturing date of 11/
2018, the steam humidifiers FLE50/65/100/
130 make use of a modified steam cylinder
that are separable in the upper part of the
wall. When replacing the steam cylinder, the
new cylinders with the designation „CY45/2“
may be incorporated in the older units as
well. With the steam cylinder modification
also the electrodes have changed. The new
electrodes only fit in the new steam cylinders.
The cylinders CY45/2 allow for unit operation
without a cylinder star even in case of high
conductivity of the cylinder water.
