4. Operation and Device Construction
4.1 Mode of Action
The Imersion Heater Principle
One to three heater elements (Pos. 8 in the exploded view,
please see cover foldout) are placed in a closed cylinder and
connected to alternating current. The cylinder is filled with tap
water, fully demineralized water or partially softened water. Heat
generated by the heater element increases water temperature to
approx. 100°C.
When fully demineralized water is used, the feed water is practically free of minerals. This ensures long life for the cylinder and
heater elements since virtually no mineral deposits can settle or
build up. Fully demineralized water minimizes the number of service / maintenance checks.
When tap water is used, some of the minerals dissolved in the
water will settle in the cylinder as solids of various compositions.
Most of these scale deposits are removed by periodic flushing or
use of a heavy-duty blow-down pump. See section "Servicing
During Operation with Tap Water".
The generated steam has a temperature of about 100°C and
minimal positive pressure ("pressureless” steam). It is virtually
demineralized and germ-free.
Page 13
4.2 Installation and Method of Operation
By pressing the control switch („Pos. I”) the humidifier is turned
on. When the hygrostat or controller signals a demand for
humidification, the inlet solenoid valve (14) opens. The solenoid
valve is designed for pressures from 100 x 10
3
to 100 x 104 Pas-
cals (1 to 10 bar).
Water is fed into the cylinder.
The water level in the cylinder must be maintained within a spec-
ified range. If the water level is too high, the ellbow acts as a
safety overflow for water drainage. If the water level is too low, it
could cause the heater element (8) to overheat. Therefore,
power supply to the heater element is shut off when water levels
are too low.
The cylinder water level is controlled by a level control (27). The
level control consists of a stainless steel cylinder with two float
switches and three reed contacts. The float switches indicate the
water level in the steam cylinder: "Dry Run", "Humidification"
and "Max. Level". The control capsule is pressure-equalized.
At the standard setting, the inlet solenoid valve (14) opens when
the water level remains below “humidification” level for 10 seconds. The water level then rises again to “humidification” level.
The steam cylinder consists of a top (16) and lower (9) part
joined with a cylinder flange. The seal between the cylinder and
cylinder base (11), as well as between the top and lower part of
the cylinder, is maintained using an o-ring.
Page 14
General survey
The heater elements are equipped with a mechanical high temperature safety. This mechanism provides a redundant safety
system in the event of excessively low water levels (“Dry Run”).
The cylinder water is periodically flushed out with a heavy-duty
blow-down pump (10).
Steam is fed into air-conditioning ducts through special steam
hoses and steam manifolds. Under normal conditions, this
steam has virtually no heating effect on the air to be humidified.
Accumulated condensate can be returned to the steam cylinder
via a condensate hose.
Direct room humidification (without ducts) is performed using fan
units (with blower and nozzle). The steam generator is connected to the fan unit with steam and condensate hoses.
Steam lines in steam bath cabins employ special steam hoses
and piping (if required). Accumulated condensate is normally
routed into the steam cabin. At a relative humidity of 100%, the
supplied steam is used to heat up the steam bath. The mou nting
location of the humidifier must always be outside of the steam
cabin.
Page 15
For maintenance purposes, the cylinder water may be drained
by pressing and holding the control switch in the „II“ position.
Risk of electrical shock!
Hazardous electrical high voltage.
In case of leakage from the humidifier, switch off the unit and
eliminate leakage.
Risk of scalding!
During blow down hot water with a temperature of about 95°C is
being drained. Avoid any contact with skin.
4.3 Internal Output Setting
Continuous control of the HeaterCompact Type steam humidifier
is achieved by proportional control of the heater element s. In this
way the humidifier can be proportionally operated across the
entire output range of 5% - 100% nominal capacity.
Page 16
5. Installation
Installation of this unit to be accomplished only by qualified
personnel (persons with completed training in the plumbing
field and in the field of electrical installation work, respectively) !
Obey all safety notes and warnings present on the unit.
Risk of electrical shock!
Hazardous electrical voltage.
During installation the unit must be disconnected from power
supply.
HygroMatik accepts no liability for damage due to faulty installation.
Attaching or installing additional components is permitted only
with the written consent of the manufacturer, or else the warranty is void.
Risk of foot injuries!
Unit may drop during mounting involving a single person.
Helping hand of a second person is required.
5.1 Steam Humidifier - environmental conditi-
ons
When selecting the location for steam humidifier installation, be
aware of the following:
• Ambient temperature must be between +5 and +40 °C
• Observe clearances specified in the diagrams below to
ensure adequate ventilation
• An Installation in a closed room requires aeration and if
neccessary temperature conditioning in order to reach the
above mentioned environmental conditions
• HygroMatik humidifiers are not suitable for direct outdoor
installation
Please note
Page 17
• Install the steam humidifier as close as possible to the
steam manifold. Use only short lengths of steam and condensate hose to ensure optimal performance
• The back surface of the steam humidifier heats up during
operation (to max. 70°C). Take care that the construction
on which the unit is mounted is not made of temperaturesensitive material
• Place the steam humidifier so that the unit is easily accessible with sufficient space to perform maintenance
• The unit’s protection class is IP20

5.1.2 Fitting Measures
Wall clearance
When determining the steam humidifier positioning, make use of
existing water connections (feed and drain).
Wall Mounting
To function properly, the steam humidifier must be installed vertically.
Measures for drills for wall mounting please see table (measures
d and e) in chapter „Equipment Dimensions”.If there is no suitable wall, it is recommended that the equipment is installed on
brackets which can be embedded in the floor.

5.2 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. Within the absorption distance, steam is visible as
mist in the air stream.
Condensation may occur on anything installed within 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.
5.2.1 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

Page 22
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

.
