With a steady-state boiling water, so-called saturated steam is formed, that is, a steam-water mix-
ture, a «fog», in which part of the water remains in an unevaporated, micro-droplet, suspended
state. Such steam is condensed not only on the skin of a person who has not even managed to
sweat, but also in the respiratory organs, causing a feeling of short of breathing, «suocation».
«Light steam» is really materially light steam, due to the absence of suspended, microscopic, heavy
drops of water. Such a steam is considered to be the right one for the bath and is appreciated by
its experts. To determine the overall comfort of the microclimate in the steam room, there is a com-
plex theoretical relationship between temperature and humidity, this relationship is not linear, it
is impossible to remember it. And, probably it is not necessary. Each person has the right to deter-
mine this ratio in accordance with his own personal preferences.
Single additions of water even on rather hot stones of a typical electric heater leads only to insig-
nicant short-term increases in humidity of the steam room and fundamentally do not solve the
problem of creating a general, long-term and comfortable temperature and humidity regime.
A prolonged and frequent pouring of stones with water leads to their accelerated cooling and,
accordingly, to a decrease in the quality of the steam. Moreover, such intensive watering without a
doubt reduces the electrical safety of the product in use.
In view of the foregoing, the LLC «Inzhkomtsentr VVD» developed, designed and produced steam
thermal electric heaters of various electrical power and modications, the construction of which
not only to determine the parameters of the temperature and humidity conditions, but also pro-
vides the technical ability to do this easily, simply and conveniently . The basis of these products is
a fundamentally new electric generator of superheated steam (EGSS).
INTRODUCTION

5
By installing in your Bathhouse (exactly THE Bathhouse, and not the sauna) a steam-thermal elec-
tric heater of sucient power, and it is determined by the previous-known ratio of parameters –
one kW per cubic meter, you get a real opportunity to control the temperature in the steam room
in automatic mode in accordance with the set parameters on the control panel (CP), and humidity
in the manual mode, also set on the CP. The duration of the steam mode generation ensures the
humidity level in the room in accordance with your personal feelings and preferences.
The absence of any particularly complex automatic devices, the general simplicity and safety of
the steam generation scheme guarantee the reliability and stability of the entire system. And the
presence in the design of the steam-thermal heater of the zone of a standard electric heater, deco-
rated with heating elements and stones for steam formation, gives the user possibility of obtaining
typical emissions of steam in the «adding» mode.
Our Company also produces autonomous electric superheated steam generators (AESSG) from
2.25 to 18 kW in various cases and designs depending on power, with a temperature of superheat-
ed steam at the outlet from 300 to 330 °С. AESSGs can be installed in ready-made equipped and
designed baths and saunas in addition to the electric or wood-burning stoves already installed in
the steam rooms to ensure comfortable humidity parameters. In this case, their operation is pro-
vided through an individual control panel with the «ON-OFF» function.
When AESSG is installed in steam rooms autonomously, stable temperature and humidity ratios are
ensured, both in the «Russian bath» modes and at lower and higher temperature conditions, at the
user’s request, including the soft, low temperature and high humidity, delicate Turkish bath mode
called «Hamam».

6
The temperature is set, as in typical electric heater, using an external control panel, and the humid-
ity corresponding to this temperature is provided by the AESSG technical parameters set by the
manufacturer.
An additional opportunity to gain saturated steam in the operating mode ensures eective aroma-
tization of steam rooms and steaming brooms when installing a phyto-isolation device or a broom
steamer, also produced by LLC «Inzhkomtsentr».

1.4.4.1 Design of superheated steam generator.
Through a heat-insulated water tank (no. 3 in Fig. 3, 4), a box-section channel is laid (no. 4, Fig. 3, 4),
in which tubular heating elements (no. 6, Fig. 3, 4) are installed. Water is heated up to its boiling
due to heat transfer through channel walls, from tubular heating elements to water. In the channel
steam ducts are installed (no. 5, Fig. 3, 4), through which steam is transferred to a lower channel
part, where it is mixed with air, which incomes from the bottom. Due to convective streams, the air-
steam mixture ows upwards, is heated to 300-330 °С and released to the room through a nozzle
(no. 7, Fig. 3, 4). The tank is lled and re-lled with water automatically, through a valve on a back
of the enclosure. (no. 2, Fig. 3, 4).
1.4.4.2 Design of stone heating unit.
The stone heating unit is a heat-insulated steel tank (no. 9, Fig. 3, 4), in which tubular heating elements
(no. 10, Fig. 3, 4) are installed. A steam-generating stone is laid into the tank. At the top, a heat
insulated door(s) is available (no. 8, Fig 3, 4), which allows either using of some heat for room heating
(the door(s) is/are open) or using all the heat for heating of the stone mass (the door(s) is/are closed).
The tubular heating elements are installed on a foundation (no. 11, Fig. 3, 4), which is equipped with
bimetal thermostats (no. 12, Fig. 3, 4), which cut the power of tubular heating elements after reaching
of a certain temperature inside the tank.
1.4.5 CP design.
The CP consists of two functional units: control panel and power unit. The CP appearance is shown
in Fig. 5.

14
1.4.5.1 The control panel includes:
• Digital temperature and humidity meter
• Temperature control with control range +30 to +125 °С
• Three separated control circuits for tubular heating elements of the
steam generator
• One control circuit for tubular heating elements, which heat stones
(air)
The control panel provides:
• Delay of Electric heater switching on up to 24 hours with a
15-minute interval
• Automatic complete switching o of the Electric heater after
6 hours, during which CP elements were not touched (factory
settings)

1.4.5.2 The control unit includes a plastic case with a text LCD (2 lines, 16 characters each) and control
buttons in its front panel. Inside the control unit, electronic components are installed, which execute
the Electric heater operation algorithm. The electronic components of the control unit are mounted on
a PCB. The control unit is equipped with a temperature and humidity sensor, which is installed beyond
the control unit, in the sweating room. The temperature sensor is connected to the control unit with an
own 5-meter cable.
1.4.5.3 The power unit consists of a plastic case, which includes electromagnetic relays, which switch
Electric heater power circuits, and the CP power unit. The power unit elements are mounted on a
board.
1.4.6 Connection diagrams of EH and CP for dierent Electric heater models are provided in Fig. 6.
EH and CP are connected using high-temperature wires with a corresponding section and screw
terminals, which are located in the CP power unit and in the EH.
1.4.7 Water is supplied to the Electric heater from an external water supply system. Water is supplied
and drained via supply hose and drain nipple (no. 1, Fig. 3, 4) in the back Electric heater panel, under
a removable case.
1.5 Instrumentation
1.5.1 The temperature and relative humidity in a sweating room are controlled using a measuring
device in the CP.
